Your Onyxia instance, today
TLDR. Here is how you can get an Onyxia instance running in a matter of seconds.
With this, you will obtain an instance operating in a degraded mode, which lacks features such as authentication, S3 explorer, secret management, etc. However, you will still have the capability to launch services from the catalog.
In this section, we will set up Onyxia from the ground up, along with all the associated technologies. This includes for S3, for OIDC, and for managing secrets.
First you'll need a Kubernetes cluster. If you have one already you can skip this section.
maintains great tutorials for Kubernetes clusters on , or .
Pick one of the three and follow the guide.
You can stop after the .
Ingress controller
Deploy an ingress controller on your cluster:
In this section we assume that:
You have a Kubernetes cluster and kubectl configured
onyxia.my-domain.net and *.lab.my-domain.net are pointing to your cluster's external address. my-domain.net being a domain that you own. You can customise "onyxia" and "lab" to your liking, for example you could chose datalab.my-domain.net and *.kub.my-domain.net.
You have an ingress controller configured with a default TLS certificate for
As of today will only work with .
This will be addressed in the near future.
Through out this guide we make as if everything was instantaneous. In reality if you are testing on a small cluster you will need to wait several minutes after hitting helm install for the services to be ready.
Use kubectl get pods to see if your pods are up and ready.
You can now access https://onyxia.my-domain.net and start services. Congratulations! 🥳
At the moment there is no authentication process, everyone can access our platform and and start services.
Let's setup Keycloak to enable users to create account and login to our Onyxia.
For deploying our Keycloak we use .
You can now login to the administration console of https://auth.lab.my-domain.net and login using the credentials you have defined with KEYCLOAK_USER and KEYCLOAK_PASSWORD.
Create a realm called "datalab" (or something else), go to Realm settings
On the tab General
User Profile Enabled: On
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.
Now our Keycloak server is fully configured we just need to update our Onyxia deployment to let it know about it.
Update the onyxia-values.yaml file that you created previously, don't forget to replace all the occurence of my-domain.net by your actual domain.
Don't forget as well to remplace the terms of services of the by your own terms of services. CORS should be enabled on those .md links (Access-Control-Allow-Origin: *).
Now that you have updated onyxia-values.yaml restart onyxia-web with the new configuration.
Now your users should be able to create account, log-in, and start services on their own Kubernetes namespace.
Onyxia-web use to get token and empowered user with storage features. We support any S3 storage compatible with this API. In this context, we are using , which is compatible with the Amazon S3 storage service and we demonstrate how to integrate it with Keycloak.
Before configuring MinIO, let's create a new client for Keycloak (from the previous existing "datalab" realm).
Create a client called "minio".
Client ID: minio
Client Protocol: openid-connect
Root URL: https://minio.lab.my-domain.net/
Complete the content of client "minio" with the following values.
Access Type: confidential
Valid Redirect URIs (two values are required): https://minio.lab.my-domain.net/* and https://minio-console.lab.my-domain.net/*
Web origins: *
Save the content, a new tab called Credentials must be appear. Navigate to Credentials tab and copy the secret value for the next section.
Navigate to Mappers tab and create a protocol Mapper.
Name: policy
Mapper Type: Hardcoded claim
Complete the content of Mapper "policy" with the following values.
Token Claim Name: policy
Claim value: stsonly
Add to ID token: on
We recommand you to follow for this installation and you must activate OIDC authentification. We will use the official Helm in this tutorial. All Helm configuration values can be found within this .
Replace
COPY_SECRET_FROM_KEYCLOAK_MINIO_CLIENTby the secret value defined into the "minio" Keycloak client (see previous section).
MinIO is now deployed and is accessible on the console url.
By default, there are 16 MinIO containers running. If this number is too large for your Kubernetes cluster, you can limit it by configuring the 'replicas' key.
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 complexe 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.
From "datalab" realm, create a client called "onyxia-minio"
Client ID: onyxia-minio
Client Protocol: openid-connect
Root URL: https://onyxia.my-domain.net/
Complete the content of client "onyxia-minio" with the following values.
Access Type: public
Valid Redirect URIs: https://onyxia.my-domain.net/*
Web origins: *
Save the content and navigate to Mappers tab and create two protocol Mappers.
Create the first Mapper called "policy".
Token Name: policy
Mapper Type: Hardcoded claim
Token Claim Name: policy
Create the second Mapper called "audience-minio".
Token Name: audience-minio
Mapper Type: Audience
_Included Custom Audience _: minio
Add to ID token
S3 storage is configured inside a region in Onyxia api. You have some options to configure this storage and let inform Onyxia web all needed informations how to generate those tokens : keycloak parameters to access storage API, duration of STS tokens, bucket name with a standard prefix and a claim in the user JWT token to generate a unique identifiant for this bucket name, whether Onyxia-web should try to to create this bucket silently or not. There is also options for projects. You should look all options for the version of your need on
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 need 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: *

hosts:

EOF
helm install onyxia onyxia/onyxia -f onyxia-values.yamlFor GCP use this command.
For Azure use this command.
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
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:
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://onyxia.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
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.
Now we want to create a Kubernetes secret containing our newly obtained certificate:
Lastly, we want to tell our ingress controller to use this TLS certificate, to do so run:
This command will open your configured text editor, go to line 56 and add:
If you are on a Mac or Window computer you can install Docker desktop then enable Kubernetes.
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, no luck for you I'm afraid.
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 and create the following DNS records:
If you have DDNS domain you can create CNAME instead example:
https://onyxia.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
SSL
In this section we will obtain a TLS certificate issued by using the commend line tool.
Now we want to create a Kubernetes secret containing our newly obtained certificate:
Ingress controller
We'll install in our cluster but any other ingress controller will do.
User registration: On
Forgot password: On
Remember me: On
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.
From: [email protected]
Host: email-smtp.us-east-2.amazonaws.com
Port: 465
Authentication: enabled

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.
