Eclipse Che devfile registry

This repository holds meta.yaml files that refer to the samples with Devfiles.

Here is an example meta.yaml file:

---
displayName: Python
description: Python Stack with Python 3.8
tags: ["Community", "Centos", "Python", "pip"]
icon: /images/python.svg
links:
  v2: https://github.com/che-samples/python-hello-world/tree/main

Here are all the supported values:

---
# the name of the stack
displayName: Python
# the description of the stack
description: Python Stack with Python 3.8
# the list of tags that will be used to search for the devfile
tags: ["Community", "Centos", "Python", "pip"]
# the path to the icon of the stack
icon: /images/python.svg
links:
  # The link to the repository of the project that contains the devfile.yaml with schemaVersion 2.x.y
  v2: https://github.com/che-samples/python-hello-world/tree/main

The contents of the devfile registry are published to GitHub pages on every commit. Furthermore, every version is also published to GitHub pages at release time. As an example the 7.31.2 version of the devfile registry was published here.

All published versions of the devfile registry explicitly use plugins from the che-plugin-registry by specifying the registryUrl field.

Build registry container image

This repository contains a build.sh script at its root that can be used to build the registry:

Usage: ./build.sh [OPTIONS]
Options:
    --help
        Print this message.
    --tag, -t [TAG]
        Docker image tag to be used for image; default: 'next'
    --registry, -r [REGISTRY]
        Docker registry to be used for image; default 'quay.io'
    --organization, -o [ORGANIZATION]
        Docker image organization to be used for image; default: 'eclipse'
    --offline
        Build offline version of registry, with all artifacts included
        cached in the registry; disabled by default.
    --rhel
        Build using the rhel.Dockerfile (UBI images) instead of default

By default, the built registry will be tagged quay.io/eclipse/che-devfile-registry:next, and will be built with offline mode disabled.

This script listens to the BUILDER variable, and will use the tool specified there to build the image. For example:

BUILDER=buildah ./build.sh

will force the build to use buildah. If BUILDER is not specified, the script will try to use podman by default. If podman is not installed, then buildah will be chosen. If neither podman nor buildah are installed, the script will finally try to build with docker.

Note that the Dockerfiles in this repository utilize multi-stage builds, so Docker version 17.05 or higher is required.

Offline and airgapped registry images

Using the --offline option in build.sh will build the registry to contain zip files for all projects referenced, which is useful for running Che in clusters that may not have access to GitHub. When building the offline registry, the docker build will

1. Clone all git projects referenced in devfiles, and
2. git archive them in the /resources path, making them available to workspaces.

When deploying this offline registry, it is necessary to set the environment variable CHE_DEVFILE_REGISTRY_URL to the URL of the route/endpoint that exposes the devfile registry, as devfiles need to be rewritten to point to internally hosted zip files.

Deploy the registry to OpenShift

You can deploy the registry to Openshift as follows:

  oc new-app -f deploy/openshift/che-devfile-registry.yaml \
             -p IMAGE="quay.io/eclipse/che-devfile-registry" \
             -p IMAGE_TAG="next" \
             -p PULL_POLICY="Always"

Kubernetes

You can deploy Che devfile registry on Kubernetes using helm. For example if you want to deploy it in the namespace kube-che and you are using minikube you can use the following command.

NAMESPACE="kube-che"
DOMAIN="$(minikube ip).nip.io"
helm upgrade --install che-devfile-registry \
    --debug \
    --namespace ${NAMESPACE} \
    --set global.ingressDomain=${DOMAIN} \
    ./deploy/kubernetes/che-devfile-registry/

You can use the following command to uninstall it.

helm delete --purge che-devfile-registry
