Onyxia API

This is the server part of the Onyxia datalab, it interacts with your container orchestrator (Kubernetes) to deploy users services.
Deployable services are listed and configured inside catalogs.
Default catalogs are from InseeFrlab : Interactive services, Databases, Automation but more catalogs (including your own) can be added.

Quick start

Onyxia-api is usually run as a component within the Onyxia stack. See Onyxia helm chart and docs.onyxia.sh for installation instruction.

Running Onyxia-API standalone

Using docker

docker run -p 8080:8080 inseefrlab/onyxia-api

Using Java / maven (from sources)

git clone https://github.com/InseeFrLab/onyxia-api.git
cd onyxia-api
mvn spring-boot:run

Usage

Once Onyxia is started, browse to http://localhost:8080 to get started with the OpenAPI documentation.

Onyxia API dependency to Helm

Onyxia-API makes system calls to helm using the helm-wrapper Java library.
helm is bundled in the Onyxia API Docker image, see current version bundled here : Dockerfile.
If running Onyxia API locally you need to have helm available in the PATH.

Onyxia Helm format extension

Onyxia's catalogs are based on the Helm chart format and especially the values.schema.json (see https://helm.sh/docs/topics/charts/#schema-files) file used to populate the personalization tabs displayed by the UI.
Onyxia is fully interoperable with the Helm chart format which means you can use any helm chart repository as a onyxia catalog. But you probably want to use one that includes values.schema.json files (those files are optional in helm).
Onyxia extends this format to enhance it and provide more customization tools in the UI.

An example of such extension can be found here, see x-onyxia.
