x-onyxia

Onyxia's JSON Schema extention

Onyxia defines a custom extension to the JSON Schema spec. It adds Onyxia-specific properties under a reserved key: x-onyxia.

The main use case is per-user defaults based on identity. For example, you can inject the right Git and S3 credentials for each user.

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.

The onyxia user profile

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

export type XOnyxiaParams = {
    /**
     * This is where you can reference values from the onyxia context so that they
     * are dynamically injected by the Onyxia launcher.
     *
     * Examples:
     * "overwriteDefaultWith": "user.email" ( You can also write "{{user.email}}" it's equivalent )
     * "overwriteDefaultWith": "{{project.id}}-{{k8s.randomSubdomain}}.{{k8s.domain}}"
     * "overwriteDefaultWith": [ "a hardcoded value", "some other hardcoded value", "{{region.oauth2.clientId}}" ]
     * "overwriteDefaultWith": { "foo": "bar", "bar": "{{region.oauth2.clientId}}" }
     *

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}}"
  }
}

overwriteListEnumWith

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

Example of select form field in the onyxia launcher

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}}"
  }
}

overwriteSchemaWith
