Install

Convinced by Onyxia? Let's see how you can get your own instance today!

Oneliner

If you are already familiar with Kubernetes and Helm, here's how you can get an Onyxia instance up and running in just a matter of seconds.

With this minimal configuration, you'll have an Onyxia instance operating in a degraded mode, which lacks features such as authentication, S3 explorer, secret management, etc. However, you will still retain the capability to launch services from the catalog.

Whether you are a Kubernetes veteran or a beginner with cloud technologies, this guide aims to guide you through the instantiation and configuration of an Onyxia instance with it's full range of features enabled. Let's dive right in! 🤿

First let's make sure we have a suitable deployment environement to work with!

Kubernetes

Provision a Kubernetes cluster

First you'll need a Kubernetes cluster. If you have one already you can skip and directly go to the Onyxia instalation section.

Hashicorp maintains great tutorials for terraforming Kubernetes clusters on AWS, GCP or Azure.

Pick one of the three and follow the guide.

You can stop after the configure kubectl section.

Ingress controller

Let's install ingress-ngnix on our newly created cluster:

The following command is for AWS.

For GCP use this command.

For Azure use this command.

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.2.0/deploy/static/provider/aws/deploy.yaml

DNS

Let's assume you own the domain name my-domain.net, for the rest of the guide you should replace my-domain.net by a domain you actually own.

Now you need to get the external address of your cluster, run the command

kubectl get services -n ingress-nginx

and write down the External IP assigned to the LoadBalancer.

Depending on the cloud provider you are using it can be an IPv4, an IPv6 or a domain. On AWS for example, it will be a domain like xxx.elb.eu-west-1.amazonaws.com.

If you see <pending>, wait a few seconds and try again.

Once you have the address, create the following DNS records:

datalab.my-domain.net CNAME xxx.elb.eu-west-1.amazonaws.com. 
*.lab.my-domain.net   CNAME xxx.elb.eu-west-1.amazonaws.com.

If the address you got was an IPv4 (x.x.x.x), create a A record instead of a CNAME.

If the address you got was ans IPv6 (y:y:y:y:y:y:y:y), create a AAAA record.

https://datalab.my-domain.net will be the URL for your instance of Onyxia. The URL of the services created by Onyxia are going to look like: https://<something>.lab.my-domain.net

You can customise "datalab" and "lab" to your liking, for example you could chose onyxia.my-domain.net and *.kub.my-domain.net.

SSL

In this section we will obtain a TLS certificate issued by LetsEncrypt using the certbot commend line tool then get our ingress controller to use it.

If you are already familiar with certbot you're probably used to run it on a remote host via SSH. In this case you are expected to run it on your own machine, we'll use the DNS chalenge instead of the HTTP chalenge.

brew install certbot #On Mac, lookup how to install certbot for your OS

#Because we need a wildcard certificate we have to complete the DNS callange.  
sudo certbot certonly --manual --preferred-challenges dns

# When asked for the domains you wish to optains a certificate for enter:
#   datalab.my-domain.net *.lab.my-domain.net

The obtained certificate needs to be renewed every three month.

To avoid the burden of having to remember to re-run the certbot command periodically you can setup cert-manager and configure a DNS01 challenge provider on your cluster but that's out of scope for Onyxia.

You may need to delegate your DNS Servers to one of the supported DNS service provider.

Now we want to create a Kubernetes secret containing our newly obtained certificate:

DOMAIN=my-domain.net
sudo kubectl create secret tls onyxia-tls \
    -n ingress-nginx \
    --key /etc/letsencrypt/live/datalab.$DOMAIN/privkey.pem \
    --cert /etc/letsencrypt/live/datalab.$DOMAIN/fullchain.pem

Lastly, we want to tell our ingress controller to use this TLS certificate, to do so run:

kubectl edit deployment ingress-nginx-controller -n ingress-nginx

This command will open your configured text editor, go to containers -> args and add:

      - --default-ssl-certificate=ingress-nginx/onyxia-tls
      - --watch-ingress-without-class

If you are on a Mac or Window computer you can install Docker desktop then enable Kubernetes.

WARNING: If you are folowing this installating guide on an Apple Sillicon Mac, be aware that many of the services that comes by default with Onyxia like Jupyter RStudio and VSCode won't run because we do not yet compile our datacience stack for the ARM64 architecture. If you would like to see this change please sumit an issue about it.

Docker desktop isn't available on Linux, you can use Kind instead.

Port Forwarding

You'll need to forward the TCP ports 80 and 443 to your local machine. It's done from the administration panel of your domestic internet Box. If you're on a corporate network you'll have to test onyxia on a remote Kubernetes cluster.

DNS

Let's assume you own the domain name my-domain.net, for the rest of the guide you should replace my-domain.net by a domain you actually own.

Get your internet box routable IP and create the following DNS records:

datalab.my-domain.net A <YOUR_IP>
*.lab.my-domain.net   A <YOUR_IP>

If you have DDNS domain you can create CNAME instead example:

datalab.my-domain.net CNAME jhon-doe-home.ddns.net.
*.lab.my-domain.net   CNAME jhon-doe-home.ddnc.net.

https://datalab.my-domain.net will be the URL for your instance of Onyxia.

The URL of the services created by Onyxia are going to look like: https://xxx.lab.my-domain.net

You can customise "datalab" and "lab" to your liking, for example you could chose onyxia.my-domain.net and *.kub.my-domain.net.

SSL

In this section we will obtain a TLS certificate issued by LetsEncrypt using the certbot commend line tool.

brew install certbot #On Mac, lookup how to install certbot for your OS

# Because we need a wildcard certificate we have to complete the DNS callange.  
sudo certbot certonly --manual --preferred-challenges dns

# When asked for the domains you wish to optains a certificate for enter:
#   datalab.my-domain.net *.lab.my-domain.net

The obtained certificate needs to be renewed every three month.

You may need to delegate your DNS Servers to one of the supported DNS service provider.

Now we want to create a Kubernetes secret containing our newly obtained certificate:

# First let's make sure we connect to our local Kube cluser
kubectl config use-context docker-desktop

kubectl create namespace ingress-nginx
DOMAIN=my-domain.net
sudo kubectl create secret tls onyxia-tls \
    -n ingress-nginx \
    --key /etc/letsencrypt/live/datalab.$DOMAIN/privkey.pem \
    --cert /etc/letsencrypt/live/datalab.$DOMAIN/fullchain.pem

Ingress controller

We will install ingress-nginx in our cluster, although any other ingress controller would be suitable as well. The configuration will be set up to handle all ingress objects, including those without a specified class, and to utilize our SSL certificate for our wildcard certificate. This approach ensures a straightforward SSL termination managed by the reverse proxy for both *.lab.my-domain.net and datalab.my-domain.net, eliminating any further concerns regarding SSL setup.

cat << EOF > ./ingress-nginx-values.yaml
controller:
  extraArgs:
    default-ssl-certificate: "ingress-nginx/onyxia-tls"
  watchIngressWithoutClass: true
EOF

helm install ingress-nginx ingress-nginx \
    --repo https://kubernetes.github.io/ingress-nginx \
    --version 4.9.1 \
    --namespace ingress-nginx \
    -f ./ingress-nginx-values.yaml

Now that we have a Kubernetes cluster ready to use let's levrage ArgoCD and GitOps practices to deploy and monitor the core services of our Onyxia Datalab.

GitOps

Let's install ArgoCD to manage and monitor our Onyxia Datalab deployment!

At this stage of this installation process we assumes that:

You have a Kubernetes cluster and kubectl configured
datalab.my-domain.net and *.lab.my-domain.net's DNS are pointing to your cluster's external address. my-domain.net being a domain that you own.
Your ingress-nginx is set up with a default TLS certificate that covers both datalab.my-domain.net and *.lab.my-domain.net, processing all ingress objects, .

We can proceed with manually installing various services via Helm to set up the datalab. However, it's more convenient and reproducible to maintain a Git repository that outlines the required services that we need for our datalab, allowing to handle the deployment for us.

To clarify, using ArgoCD is merely an approach that we recommend, but it is by no means a requirement. Feel free to manually helm install the different services using the values.yaml from !

Let's install ArgoCD on the our cluster.

Now you have to get the password that have been automatically generated to protect ArgoCD's admin console. Allow some time for ArgoCD to strart, you can follow the progress by running kubectl get pods and making sure that all pod are ready 1/1. After that running this command will print the password:

You can now login to https://argocd.lab.my-domain.net using:

username: admin
password: <the output of the previous command (without the % at the end)>

Now that we have an ArgoCD we want to connect it to a Git repository that will describe what services we want to be running on our cluster.

Let's fork the onyxia-ops GitHub repo and use it to deploy an Onyxia instance!

At this point you should have a very bare bone Onyxia instance that you can use to launch services.

What's great, is that now, if you want to update the configuration of your Onyxia instance you only have to commit the change to your GitOps repo, ArgoCD will takes charge of restarting the service for you with the new configuration. To put that to the test try to modify your Onyxia configuration by setting up a global alert that will be shown as a banner to all users!

After a few seconds, if you reload https://datalab.my-domain.net you should see the message!

Next step is to see how to enable your user to authenticate themselvs to your datalab!

User authentication

Using Keycloak to enable user authentication

Let's setup Keycloak to enable users to create account and login to our Onyxia.

Note that in this instalation guide we make you use Keycloak but you can use any identity server that is Open ID Connect compliant.

Deploying Keycloak

We're going to install Keycloak just like we installed Onyxia.

Before anything open apps/keycloak/values.yaml in your onyxia-ops repo and . Also write down the keycloak.auth.adminPassword, you'll need it to connect to the Keycloak console.

Try to remember, when you update Onyxia in apps/onyxia/Chart.yaml to also update the Onyxia theme in apps/keycloak/values.yaml.

Configuring Keycloak

You can now login to the administration console of https://auth.lab.my-domain.net/auth/ and login using username: keycloak and password: <the one you've wrote down earlier>.

Create a realm called "datalab" (or something else), go to Realm settings
1. On the tab General
  1. User Profile Enabled: On
2. On the tab login
  1. User registration: On
  2. Forgot password: On
  3. Remember me: On
3. On the tab email, we give an example with AWS SES, if you don't have a SMTP server at hand you can skip this by going to Authentication (on the left panel) -> Tab Required Actions -> Uncheck "set as default action" Verify Email. Be aware that with email verification disable, anyone will be able to sign up to your service.
  1. From: noreply@lab.my-domain.net
  2. Host: email-smtp.us-east-2.amazonaws.com
  3. Port: 465
  4. Authentication: enabled
  5. Username: **************
  6. Password: ***************************************
  7. When clicking "save" you'll be asked for a test email, you have to provide one that correspond to a pre-existing user or you will get a silent error and the credentials won't be saved.
4. On the tab Themes
  1. Login theme: onyxia-web (you can also select the login theme on a per client basis)
  2. Email theme: onyxia-web
5. On the tab Localization
  1. Internationalization: Enabled
  2. Supported locales: <Select the languages you wish to support>
6. On the tab Session.
  1. SSO Session Idle:
  2. SSO Session Max:
  3. SSO Session Idle Remember Me:
  4. SSO Session Max Remember Me: 14 days
Create a client with client ID "onyxia"
1. Root URL: https://datalab.my-domain.net/
2. Valid redirect URIs: https://datalab.my-domain.net/*
3. Web origins: *
4. Login theme: onyxia-web
In Authentication (on the left panel) -> Tab Required Actions enable and set as default action Therms and Conditions.

Now you want to ensure that the username chosen by your users complies with Onyxia requirement (only alphanumerical characters) and define a list of email domain allowed to register to your service.

Go to Realm Settings (on the left panel) -> Tab User Profile (this tab shows up only if User Profile is enabled in the General tab and you can enable user profile only if you have started Keycloak with -Dkeycloak.profile=preview) -> JSON Editor.

Now you can edit the file as suggested in the following DIFF snippet. Be mindful that in this example we only allow emails @gmail.com and @hotmail.com to register you want to edit that.

{
  "attributes": [
    {
      "name": "username",
      "displayName": "${username}",
      "validations": {
        "length": {
          "min": 3,
          "max": 255
        },
+       "pattern": {
+         "error-message": "${lowerCaseAlphanumericalCharsOnly}",
+         "pattern": "^[a-z0-9]*$"
+       },
        "username-prohibited-characters": {}
      }
    },
    {
      "name": "email",
      "displayName": "${email}",
      "validations": {
        "email": {},
+       "pattern": {
+         "pattern": "^[^@]+@([^.]+\\.)*((gmail\\.com)|(hotmail\\.com))$"
+       },
        "length": {
          "max": 255
        }
      }
    },
...

Now our Keycloak server is fully configured we just need to update our Onyxia deployment to let it know about it.

Updating the Onyxia configuration

In your GitOps repo you now want to update your onyxia configuration.

git clone https://github.com/<your-github-org>/onyxia-ops
cd onyxia-ops
cd apps/onyxia
mv values-keycloak-enabled.yaml values.yaml
git commit -am "Enable keycloak"
git push

Here is the DIFF of the onyxia configuration:

Now your users should be able to create account, log-in, and start services on their own Kubernetes namespace.

Next step in the installation proccess it to enable all the S3 related features of Onyxia:

Data (S3)

Enable S3 storage via MinIO S3

Onyxia uses AWS Security Token Service API to obtain S3 tokens on behalf of your users. We support any S3 storage compatible with this API. In this context, we are using MinIO, which is compatible with the Amazon S3 storage service and we demonstrate how to integrate it with Keycloak.

Creating the 'minio' Keycloak client

Before configuring MinIO, let's create a new Keycloak client (from the previous existing "datalab" realm).

Deploying MinIO

Before deploying MinIO on the cluster let's set, in the MinIO configuration file, the OIDC client secret we have copied in the previous step.

git clone https://github.com/<your-github-org>/onyxia-ops
cd onyxia-ops
cd apps/minio
# In the values.yaml file replace `$KEYCLOAK_MINIO_CLIENT_SECRET` by the value
# you have copied in the previous step.
git commit -am "Set minio OIDC client secret"
git push

Once you've done that you can deploy MinIO!

Creating the 'onyxia-minio' Keycloak client

Before configuring the onyxia region to create tokens we should go back to Keycloak and create a new client to enable onyxia-web to request token for MinIO. This client is a little bit more complex than other if you want to manage durations (here 7 days) and this client should have a claim name policy and with a value of stsonly according to our last deployment of MinIO.

Updating the Onyxia configuration

Now let's update our Onyxia configuration to let it know that there is now a S3 server available on the cluster.

git clone https://github.com/<your-github-org>/onyxia-ops
cd onyxia-ops
cd apps/onyxia
mv values-minio-enabled.yaml.yaml values.yaml
git commit -am "Enable MinIO"
git push

Diff of the changes applied to the Onyxia configuration:

Congratulation, all the S3 related features of Onyxia are now enabled in your instance! Now if you navigate to your Onyxia instance you should have My Files in the left menu.

Next step in the installation process is to setup Vault to provide a way to your user so store secret and also to provide something that Onyxia can use as a persistance layer for user configurations.

Vault

Let's use hashicorp Vault for storing the user secrets.

Vault is also used by Onyxia as the persistance layer for all saved configuration. If you don't have a vault all user settings are stored in the local storage.

Onyxia-web use vault as a storage for two kinds of secrets : 1. secrets or information generate by Onyxia to store differents values (ui preferences for example) 2. user secrets Vault must be configured with JWT or OIDC authentification methods.

As vault needs to be initialized with a master key, it can't be directly configured with all parameters such as oidc or access policies and roles. So first step we create a vault with dev mode (do not use this in production and do your initialization with any of the recommanded configuration : shamir, gcp, another vault)

Create a client called "vault"

Root URL: https://vault.lab.my-domain.net/
Valid redirect URIs: https://vault.lab.my-domain.net/*
Web origins: *

Theme and branding

Customize your Onyxia instance with your assets and your colors, make it your own!

The full documentation of the available parameter can be found here:

Note that your custom assets are imported into your Onyxia instance via the use of the CUSTOM_RESOURCES parameter, url of a ZIP archive that should contain your assets. An example is given at the top of the .env file.

Onyxia is configured to make the the browser cache assets so they are not re-downloaded each time the user access the app.

If you update some of your asset but keep the same URL, you can force the browser of your users to download the new version by adding a query parameter to the URL. Eample:

HEADER_LOGO: "%PUBLIC_URL%/custom-resources/logo.svg?v=2"

Make sure to checkout the version of this document that matches the Onyxia version that you are deploying. See releases.

Here are two base look that you can use a starting point of your configuration.

Setting up group projects

Enabling a group of users to share the same Kubernetes namespace to work on something together.

The user interface of onyxia enables to create projects for groups of Onyxia users.

Users will be able to dynamically switch from one project to another using a select input in the header.

This select doesn't appear when the user isn't in any group project.

All users of a group project share:

The Kubernetes namespace, in "My Services" you can see everything that's running, including services launched by other person of the group.
Project settings. If a user change a project setting, it affects every member of the group.
Secrets
S3 Bucket (or an S3 subpath)

As of today, new group can only be created by Onyxia instance administrator, on demand and the procedure to create group is not publicly documented yet because we're still actively working on it. However, if you want to enable this feature for your users, reach us, we will guide you through it!

Security consideration

Information about security considerations

1. Autolaunch Feature

The autolaunch feature empowers you to create HTTP links that automatically deploy an environment. This is an invaluable tool for initiating trainings effortlessly. However, exercise caution while using it as it could pose a security risk to the user. Consider disabling this feature if it doesn't suit your requirements or if security is a primary concern.

Disable Autolaunch

2. Group Feature

Onyxia is primarily designed to allocate resources such as a namespace and an S3 bucket to an individual user for work purposes. Additionally, it incorporates a feature that allows multiple users to share access to the same resources within a project. While this can be extremely beneficial for collaboration, be aware that it might be exploited by a malicious user within the group to leverage the privileges of another project member. Always monitor shared resources and maintain proper user access control to prevent such security breaches.

Migration guides

v8 -> v9

tl;dr: Breaking change, defaultConfiguration in region configuration is not allowed anymore and has been replaced by JSONSchemas override using the new api.schemas key from v9 helm chart.

Onyxia v9 allows administrators to define custom JSON schemas, allowing them to override the default schemas provided by the chart. Prior to this change, Onyxia relied on providing default values for specific keys in the region configuration : defaultConfiguration.

Chart owners can now define which properties can be overridden using a JSON Schema.

Here is an example of a Chart that supports JSONSchemas (taken from the default IDE catalog, see this link) :

values.schema.json

"nodeSelector": {
      "type": "object",
      "description": "NodeSelector",
      "default": {},
      "x-onyxia": {
          "hidden": false,
          "overwriteDefaultWith": "region.nodeSelector",
          "overwriteSchemaWith": "nodeSelector.json"
      }
    }

The overwriteDefaultWith attribute was the old method for overriding, instructing Onyxia to use the "defaultConfiguration" from the Region. This method is no longer supported in v9, though it can still be used for catalog compatibility with v8.

In v9, overwriteDefaultWith has been replaced by overwriteSchemaWith, which offers more flexibility due to the capabilities of JSON Schemas. Default schemas are bundled with Onyxia-API and will be used if no override is provided. You can find these default schemas here: Onyxia-API Schemas.

To override a schema, use the new schemas key from the v9 Helm chart and provide the list of schemas you want to override. For more details, refer to the documentation: Onyxia v9 Catalog.

Onyxia v9 will fail to start with error message :

FATAL : Setting defaultConfiguration in region is no longer supported and has been replaced by JSONSchema support. See migration guide at https://docs.onyxia.sh/admin-doc/migration-guides/v8-greater-than-v9

if you don't remove the defaultConfiguration from the region configuration.

v7 -> v8

You can now have comments, trailing comas and single quotes in your region and catalog parameters! See .

In this release, the Onyxia S3 integration has been completely revamped!

This is the DIFF you have to apply to your Onyxia configuration assuming you have a typical MinIO integration configured:

v6 -> v7

In this major version a lot of the parameters of the webapp have been updated/refined. Here is the changes you need to apply to your values.json to migrate smoothly.

The `THEME_ID` parameter has been removed.

Onyxia is now fully customizable instead of just letting you pick within a handful of predefined themes.

If you where using the `france` theme:

If you where using the `ultraviolet` theme:

If you where using the `verdant` theme:

Header parameters

Links in the header and the left bar

Assets must now be bundled

Keycloak Theme

v5 -> v6

The only breaking change in this release is the split of Onyxia service account into two separate service accounts : one for the API (which usually requires high permission to deploy services) and one for the WEB pod (qui usually should not have any permissions tied to it). Due to this change, the global serviceAccount values key was duplicated in both web.serviceAccount and api.serviceAccount. See:

and

Example of change :

onyxia-values.yaml

onyxia:
-  serviceAccount:
-    create: true
-    clusterAdmin: true
   api:
+    serviceAccount:
+      create: true
+      clusterAdmin: true
   web:
+    serviceAccount:
+      create: true

v4 -> v5

The primary breaking change in this release pertains to Keycloak configuration. With this update, you're no longer limited to using Keycloak; any OIDC-compliant identity provider is now supported. To accommodate this new feature, you'll need to make some adjustments to the configuration of your Onyxia instance.

You don't need to specify the issuerURI in multiple locations as we have done here. If you're using just one identity server (You have only one Keycloak server for example), you can set the issuerURI solely in api->env->oidc.issuer-uri.

onyxia-values.yaml

onyxia:
   web:

Migrating to the new helm repo

Previously, the Helm chart of Onyxia was hosted on the inseefrlab/helm-charts repo and has now been moved to inseefrlab/onyxia. As a result you would now install Onyxia like this:

In the following we assume the current version of Onyxia is 4.1.4 but you are encorging to use the latest version instead. .

If you use ArgoCD for deploying onyxia:

You no longer need to manually manage the version of and , now, if you want to update Onyxia, you just update the chart version number.

For the Keycloak theme, the version is now synchronized with the Onyxia version.

Also note that, the theme will now appear as "onyxia" in the dropdown. Previously it was "onyxia-web"

The Web Application

The TypeScript App that runs in the browser.

This is the documentation for .

You have a video here where we guide you through the setup of the dev environnement:

Technical stack

Technologies at play in Onyxia-web

To find your way in Onyxia, the best approach is to start by getting a surface-level understanding of the libraries that are leveraged in the project.

Modules marked by 🐔 are our own.

tsafe 🐔

We also heavily rely on tsafe. It's a collection of utilities that help write cleaner TypeScript code. It is crutial to understand at least assert, id, Equals and symToStr to be able to contribute on the codebase.

For working on what the end user 👁

Anything contained in the src/ui directory.

Onyxia-UI 🐔

The UI toolkit used in the project, you can find the setup of onyxia-UI in onyxia-web here: src/ui/theme.tsx.

MUI integration

Onyxia-UI is fully compatible with MUI.

Onyxia-UI offers a library of reusable components but you can also use MUI components in the project, their aspect will automatically be adapted to blend in with the theme.

🔡 Linking onyxia-ui in onyxia-web

To release a new version of Onyxia-UI. You just need to bump the package.json's version and push. The CI will automate publish a new version on NPM.

If you want to test some changes made to onyxia-ui in onyxia-web before releasing a new version of onyxia-ui to NPM you can link locally onyxia-ui in onyxia-web.

cd ~/github
git clone https//github.com/InseeFrLab/onyxia
cd onyxia/web
yarn install

cd ~/github/onyxia #This is just a suggestion, clone wherever you see fit.
git clone https://github.com/InseeFrLab/onyxia-ui ui
cd ui
yarn install
yarn build
yarn link-in-web
npx tsc -w

# Open a new terminal
cd ~/github/onyxia/web
yarn start

Now you can make changes in ~/github/onyxia/ui/and see the live updates.

If you want to install/update some dependencies, you must remove the node_modules, do you updates, then link again.

tss-react 🐔

The library we use for styling.

Rules of thumbs when it comes to styling:

Every component should accept an optional classNameprop it should always overwrite the internal styles.
A component should not size or position itself. It should always be the responsibility of the parent component to do it. In other words, you should never have height, width, top, left, right, bottom or margin in the root styles of your components.
You should never have a color or a dimension hardcoded elsewhere than in the theme configuration. Use theme.spacing() (ex1, ex2, ex3) and theme.colors.useCases.xxx.

screen-scaler 🐔

Onyxia is mostly used on desktop computer screens. It's not worth the effort to create a fully flege responsive design for the UI. screen-scaler enables us to design for a sigle canonical screen size. The library take charge of scaling/shrinking the image. depending on the real size of the screen. It also asks to rotate the screen when the app is rendered in protrait mode.

Storybook

It enables us to test the graphical components in isolation. See sources.

To launch Storybook locally run the following command:

yarn storybook

vite-envs 🐔

We need to be able to do:

docker run --env OIDC_URL="https://url-of-our-keycloak.fr/auth" InseeFrLab/onyxia-web

Then, somehow, access OIDC_URL in the code like process.env["OIDC_URL"].

In theory it shouldn't be possible, onyxia-web is an SPA, it is just static JS/CSS/HTML. If we want to bundle values in the code, we should have to recompile. But this is where cra-envs comes into play.

It enables to run onyxia-web again a specific infrastructure while keeping the app docker image generic.

Checkout the helm chart:

  web:
    replicaCount: 2
    env:
      MINIO_URL: https://minio.lab.sspcloud.fr
      VAULT_URL: https://vault.lab.sspcloud.fr
      OIDC_URL: https://auth.lab.sspcloud.fr/auth
      OIDC_REALM: sspcloud
      TITLE: SSP Cloud

All the accepted environment variables are defined here: .env. They are all prefixed with REACT_APP_ to be compatible with create-react-app. Default values are defined in this file.
Only in development (yarn start) .env.local is also loaded and have priority over .env
Then, in the code the variable can be accessed like this.

Please try not to access the environment variable to liberally through out the code. In principle they should only be accessed here. We try to keep things pure as much as possible.

powerhooks 🐔

It's a collection general purpose react hooks. Let's document the few use cases you absolutely need to understand:

Avoiding useless re-render of Components

For the sake of performance we enforce that every component be wrapped into React.memo(). It makes that a component only re-render if one of their prop has changed.

However if you use inline functions or useCallback as callbacks props your components will re-render every time anyway:

We always use useConstCallback for callback props. And useCallbackFactory for callback prop in lists.

Measuring Components

It is very handy to be able to get the height and the width of components dynamically. It prevents from having to hardcode dimension when we don’t need to. For that we use useDomRect``

Keycloakify 🐔

It's a build tool that enables to implement the login and register pages that users see when they are redirected to Keycloak for authentication.

If the app is being run on Keycloak the kcContext isn't undefined and it means shat we should render the login/register pages.

If you want to test, uncomment this line and run yarn start. You can also test the login pages in a local keycloak container by running yarn keycloak. All the instructions will be printed on the console.

The keycloak-theme.jar file is automatically build and uploaded as a GitHub release asset by the CI.

type-routes

The library we use for routing. It's like react-router but type safe.

i18nifty 🐔

For internalization and translation.

Vite

For working on 🧠 of the App

Anything contained in the src/core directory.

clean-architecture 🐔

The framework used to implement strict separation of concern betwen the UI and the Core and high modularity of the code.

There is a snake game (the classic nokia game) example for helping you understand the clean architecture framework.

oidc-spa 🐔

For everything related to user authentication.

EVT 🐔

EVT is an event management library (like RxJS is).

A lot of the things we do is powered under the hood by EVT. You don't need to know EVT to work on onyxia-web however, in order to demystify the parts of the codes that involve it, here are the key ideas to take away:

If we need to perform particular actions when a value gets changed, we useStatefullEvt.
We use Ctxto detaches event handlers when we no longer need them. (See line 108 on this playground)
In React, we use the useEvt hook to work with DOM events.

Architecture

Main rules

src/ui contains the React application, it's the UI of the app.
src/core contains the 🧠 of the app.
- Nothing in the src/core directory should relate to React. A concept like react hooks for example is out of scope for the src/core directory.
- src/core should never import anything from src/ui, even types.
- It should be possible for example to port onyxia-web to Vue.js or React Native without changing anything to the src/core directory.
- The goal of src/core is to expose an API that serves the UI.
- The API exposed should be reactive. We should not expose to the UI functions that returns promises, instead, the functions we expose should update states and the UI should react to these states updates.

Architecture

Whenever we need to interact with the infrastructure we define a port in src/core/port. A port is only a type definition. In our case the infrastructure is: the Keycloak server, the Vault server, the Minio server and a Kubernetes API (Onyxia-API).
In src/core/adapters are the implementations of the ports. For each port we should have at least two implementations, a dummy and a real one. It enabled the app to still run, be it in degraded mode, if one piece of the infrastructure is missing. Say we don’t have a Vault server we should still be able to launch containers.
In src/lib/usecases we expose APIs for the UI to consume.

The following framework is the backbone of onyxia-web, if you can familiarize yourself with it it will make working with onyxia-web much easyer.

In practice

Let's say we want to create a new page in onyxia-web where users can type in a repo name and get the current number of stars the repo has on GitHub.

UPDATE: This video remain relevant but please not that the clean archi setup have been considerably improved in latest releases. A dedicated repo have been created to explain it in detail.

Main take-way is that app have been renamed ui and lib have been renamed core.

You might wonder why some values, instead of being redux state, are returned by thunks functions.

For example, it might seem more natural to do:

const { isUserLoggedIn } = useCoreState(state => state.userAuthentication);

Instead of what we actually do, which is:

const { userAuthenticationThunks } = useThunks();
const isUserLoggedIn = userAuthenticationThunks.getIsUserLoggedIn();

However the rule is to never store as a redux state, values that are not susceptible to change. Redux states are values that we observe, any redux state changes should trigger a re-render of the React components that uses them. Conversely, there is no need to observe a value that will never change. We can get it once and never again, get it in a callback or wherever.

But, you may object, users do login and logout, isUserLoggedIn is not a constant!

Actually, from the standpoint of the web app, it is. When a user that isn't authenticated click on the login button, it is being redirected away. When he returns to the app everything is reloaded from scratch.

Now let's say we want the search to be restricted to a given GitHub organization. (Example: InseeFrLab.) The GitHub organization should be specified as an environment variable by the person in charge of deploying Onyxia. e.g.:

  web:
    env:
      MINIO_URL: https://minio.lab.sspcloud.fr
      VAULT_URL: https://vault.lab.sspcloud.fr
      OIDC_URL: https://auth.lab.sspcloud.fr/auth
      OIDC_REALM: sspcloud
      TITLE: SSP Cloud
      ORG_NAME: InseeFrLab #<==========

If no ORG_NAME is provided by the administrator, the app should always show 999 stars for any repo name queried.

Another example: Recording user's GitLab token

Currently users can save their GitHub Personal access token in their Onyxia account but not yet their GitLab token. Let's see how we would implement that.

How to deal with project switching

The easy action to take when the user selects another project is to simply reload the page (windows.location.reload()). We want to avoid doing this to enable what we call "hot projet swiping":

To implement this behavior you have to leverage the evtAction middleware from clean-redux. It enabled to register functions to be run when certain actions are dispatched.

Unlike the other video, the following one is voiced. Find the relevant code here.

The REST API

The backend REST API in Java

This is the documentation for InseeFrLab/onyxia -> api/.

It's the part of the App that runs in the clusters. It handles the things that can't be done directly from the frontend.

user doc

Getting started with Onyxia

Using Onyxia (as a data scientist)

Start a service

Following is a documentation Onyxia when configured with the default service catalogs :

This collection of charts help users to launch many IDE with various binary stacks (python , R) with or without GPU support. Docker images are built here and help us to give a homogeneous stack.

This collection of charts help users to launch many databases system. Most of them are based on bitnami/charts.

This collection of charts help users to start automation tools for their datascience activity.

This collection of charts helps users to launch tools to visualize and share data insights.

The Onyxia user experience may be very different from one catalog of service to another.

The catalog defines what options are available though Onyxia.

Users can edit various parameters. Onyxia do some assertion based on the charts values schema and the configuration on the instance. For example some identity token can be injected by default (because Onyxia connect users to many APIs).

After launching a service, notes are shown to the user. He can retrieve those notes on the README button. Charts administrator should explain how to connect to the services (url , account) and what happens on deletion.

Now you want to learn how to setup your devloppement environement for day to day usage:

File browser

Users can manage their files on S3. There is no support for rename in S3 so don't be surprise. Onyxia is educational. Any action on the S3 browser in the UI is written in a console with a cli.

User can do the following S3 actions :

download files
upload files
delete files

Of course, in our default catalags there are all the necessary tools to connect to S3.

Our advice is to never download file to your container but directly ingest in memory the data.

Secret browser

Users can mange their secrets on Vault. There is also a cli console.

Onyxia use only a key value v2 secret engine in Vault. Users can store some secrets there and inject them in their services if configured by the helm chart.

Of course, in our default catalags there are all the necessary tools to connect to Vault.

Datascience Trainings and Tutorials

The Onyxia team maintain a catalog of training and tutorials with several practical exercices that can be performed on an Onyxia instance!

By default the when you open the trainings will be open on https://datalab.sspcloud.fr (our onyxia instance) but if you don't have a Datalab acount you can edit the urls of the practical exercises so you can run them on the instance you have access to.

Setting up your dev environment in Onyxia

In this video, we guide you through setting up your development environment in Onyxia. We demonstrate how to automatically clone your Git repository, install any missing dependencies, and open a port for your development server.

You can also find initialization scripts of interactive services here.

I forgot to show in the video that you can setup your GitHub/GitLab username and token in My Account -> External services.

This will enable Onyxia to clone private repos!

Community resources

You can find extra information on how to use Onyxia as a datascientist by checking out the community website of the french statistician workforce. It's in french though.

Want to share something you've done with Onyxia? You can click on "edit this page on GitHub" and submit a pull request!

Catalog of services

Unserstand how Onyxia catalogs work and potentially create your own!

Every Onyxia instance may or may not have it's own catalog. There are four default catalogs :

This collection of charts helps users to launch many IDE with various binary stacks (python , R) with or without GPU support. Docker images are built here and help us to give a homogeneous stack.

This collection of charts helps users to launch many databases system. Most of them are based on bitnami/charts.

GitHub - InseeFrLab/helm-charts-automationGitHub

This collection of charts helps users to start automation tools for their datascience activity.

GitHub - InseeFrLab/helm-charts-datavisualizationGitHub

This collection of charts helps users to launch tools to visualize and share data insights.

You can always find the source of the catalog by clicking on the "contribute to the... " link.

If you take this other instance, it has only one catalog, helm-charts-sill.

Using your own catalogs (helm charts repositories)

If you do not specify catalogs in your onyxia/values.yaml, these are the ones that are used by default: See file.

To configure your onyxia instance to use your own custom helm repositories as onyxia catalogs you need to use the onyxia configuration onyxia.api.catalogs. Let's say we're NASA and we want to have an "Areospace services" catalog on our onyxia instance. Our onyxia configuration would look a bit like this:

onyxia/values.yaml

onyxia:
  web:
    # ...
  api:
    # ...
    catalogs: [
      {
        type: "helm",

        highlightedCharts: ["jupyter-artemis", "rstudio-dragonfly"],
        # Optional. Defines the chart that should be excluded
        excludedCharts: ["a-vendor-locking-chart"],
        # Optional, If defined, displayed in the header of the catalog page:

        },
        # Can be "PROD" or "TEST". If test the catalogs will be accessible if you type the url in the search bar

        restrictions: [
          {
            userAttribute: {
              key: "groups",
              matches: "nasa-engineers"
            }
          }
        ]
      },
       # { ... } another catalog
    ]

Customizing your helm charts for Onyxia

In Onyxia we use the values.schema.json file to know what options should be displayed to the user at the service configuration step and what default value Onyxia should inject.

[x-onyxia] overwriteDefaultWith

Let's consider a sample of the values.schema.json of the InseeFrLab/helm-charts-interactive-services' Jupyter chart:

values.schema.json

"git": {
    "description": "Git user configuration",
    "type": "object",
    "properties": {
        "enabled": {
            "type": "boolean",
            "description": "Add git config inside your environment",
            "default": true
        },
        "name": {
            "type": "string",
            "description": "user name for git",
            "default": "",
            "x-onyxia": {
                "overwriteDefaultWith": "git.name"
            },
            "hidden": {
                "value": false,
                "path": "git/enabled"
            }
        },
        "email": {
            "type": "string",
            "description": "user email for git",
            "default": "",
            "x-onyxia": {
                "overwriteDefaultWith": "git.email"
            },
            "hidden": {
                "value": false,
                "path": "git/enabled"
            }
        },
        "cache": {
            "type": "string",
            "description": "duration in seconds of the credentials cache duration",
            "default": "",
            "x-onyxia": {
                "overwriteDefaultWith": "git.credentials_cache_duration"
            },
            "hidden": {
                "value": false,
                "path": "git/enabled"
            }
        },
        "token": {
            "type": "string",
            "description": "personal access token",
            "default": "",
            "x-onyxia": {
                "overwriteDefaultWith": "git.token"
            },
            "hidden": {
                "value": false,
                "path": "git/enabled"
            }
        },
        "repository": {
            "type": "string",
            "description": "Repository url",
            "default": "",
            "hidden": {
                "value": false,
                "path": "git/enabled"
            }
        },
        "branch": {
            "type": "string",
            "description": "Brach automatically checkout",
            "default": "",
            "hidden": {
                "value": "",
                "path": "git/repository"
            }
        }
    }
},

And it translates into this:

Note the "git.name", "git.email" and "git.token", this enables onyxia-web to pre fill the fields.

If the user took the time to fill its profile information, onyxia-web knows what is the Git username, email and personal access token of the user.

Here is defined the structure of the context that you can use in the overwriteDefaultWith field:

export type XOnyxiaParams = {

You can also concatenate string values using by wrapping the XOnyxia targeted values in {{}}.

values.shema.json

"hostname": {
  "type": "string",
  "form": true,
  "title": "Hostname",
  "x-onyxia": {
    "overwriteDefaultWith": "{{project.id}}-{{k8s.randomSubdomain}}.{{k8s.domain}}"
  }
}

[x-onyxia] overwriteListEnumWith

This is an option for customizing the options of the forms fields rendered as select.

In your values shema such a field would be defined like:

values.shema.json

"pullPolicy": {
    "type": "string",
    "default": "IfNotPresent",
    "listEnum": [
        "IfNotPresent",
        "Always",
        "Never"
    ]
}

But what if you want to dynamically generate the option? For this you can use the overwriteListEnumWith x-onyxia option. For example if you need to let the user select one of the groups he belongs to you can write:

values.schema.json

"group": {
  "type": "string",
  "default": "",
  "listEnum": [""],
  "x-onyxia": {
    "overwriteDefaultWith": "user.decodedIdToken.groups[0]",
    "overwriteListEnumWith": "user.decodedIdToken.groups"
  }
}

[x-onyxia] overwriteSchemaWith

Certain elements of a Helm chart should be customized for each instance of Onyxia, such as resource requests and limits, node selectors and tolerations. For this purpose, chart developers can use x-onyxia.overwriteSchemaWith to allow administrators to override specific parts of the schema. Our default charts use this specification.

values.shema.json

"nodeSelector": {
    "type": "object",
    "description": "NodeSelector",
    "default": {},
    "x-onyxia": {
        "overwriteSchemaWith": "nodeSelector.json"
    }
}

You can see here the list of default schemas included in the Onyxia API. We also provide examples demonstrating how you can customize your services using our interactive services charts with the provided schemas.

The following node selector schema provided by Onyxia API is a generic definition, which may not provide the best experience for a specific Kubernetes cluster in Onyxia.

nodeSelector.json

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "title": "Node Selector",
    "type": "object",
    "description": "Node selector constraints for the pod",
    "additionalProperties": {
      "type": "string",
      "description": "Key-value pairs to select nodes"
    }
}

As an administrator of Onyxia, you can provide your own schemas to refine and restrict the initial schemas provided in the Helm chart.

node selectors

You can provide this schema to allow your users to choose between SSD or HDD disk types, and A2 or H100 NVIDIA GPUs. Any other values or labels are disallowed, and Onyxia will reject starting a service that does not comply with the provided schema.

nodeSelector.json

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Node Selector",
  "type": "object",
  "properties": {
    "disktype": {
      "description": "The type of disk",
      "type": "string",
      "enum": ["ssd", "hdd"]
    },
    "gpu": {
      "description": "The type of GPU",
      "type": "string",
      "enum": ["A2", "H100"]
    }
  },
  "additionalProperties": false //any other label is disallowed
}

rolebindings for IDE pods

This is the default role for IDE pods in our charts. It is very permissive, and you may want to restrict it to view-only access.

ide/role.json

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "title": "Role",
    "type": "object",
    "properties": {
        "enabled": {
            "type": "boolean",
            "description": "allow your service to access your namespace ressources",
            "default": true
        },
        "role": {
            "type": "string",
            "description": "bind your service account to this kubernetes default role",
            "default": "view",
            "enum": [
                "view",
                "edit",
                "admin"
            ]
        }
    }
}

Here is the refined version

ide/role.json

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "Role",
  "type": "object",
  "properties": {
    "enabled": {
      "type": "boolean",
      "const": true,
      "description": "This value must always be true, allowing your service to access your namespace resources."
    },
    "role": {
      "type": "string",
      "const": "view",
      "description": "This value must always be 'view', binding your service account to this Kubernetes default role.",
    }
  }
}

resources for IDE

You may want to modify the slide bar for resources

ide/resources.json

    "title": "Resources",
    "description": "Your service will have at least the requested resources and never more than its limits. No limit for a resource and you can consume everything left on the host machine.",
