Eclipse Che plugin registry

This repository holds ready-to-use plugins for different languages and technologies.

Building and publishing third party VSIX extensions for plugin registry

See: https://github.com/redhat-developer/codeready-workspaces/blob/master/devdoc/building/build-vsix-extension.adoc

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: 'nightly'
    --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'
    --latest-only
        Build registry to only contain 'latest' meta.yamls; default: 'false'
    --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

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 all referenced extension artifacts (i.e. all .theia and .vsix archives). The offline version of the plugin registry is useful in network-limited scenarios, as it avoids the need to download plugin extensions from the outside internet.

Deploy the registry to OpenShift

You can deploy the registry to Openshift as follows:

  oc new-app -f deploy/openshift/che-plugin-registry.yml \
             -p IMAGE="quay.io/eclipse/che-plugin-registry" \
             -p IMAGE_TAG="nightly" \
             -p PULL_POLICY="Always"

Run Eclipse Che plugin registry on Kubernetes

You can deploy Che plugin 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-plugin-registry \
    --debug \
    --namespace ${NAMESPACE} \
    --set global.ingressDomain=${DOMAIN} \
    ./kubernetes/che-plugin-registry/

You can use the following command to uninstall it.

helm delete --purge che-plugin-registry

Run the registry

docker run -it  --rm  -p 8080:8080 quay.io/eclipse/che-plugin-registry:nightly

1 - Category must be equal to one of the following: "Editor", "Debugger", "Formatter", "Language", "Linter", "Snippet", "Theme", "Other"

2 - firstPublicationDate is not required to be present in YAML, as if not present, it will be generated during Plugin Registry dockerimage build

3 - latestUpdateDate is not required to be present in YAML, as it will be generated during Plugin Registry dockerimage build

4 - extensions starting with relative:extension are resolved relative to the path of index.json -- e.g. v3. This is primarily to support an offline or airgapped instance of the plugin registry. See Offline and airgapped registry images for details.

Note that the spec section above comes from the older che-plugin.yaml spec. The endpoints, containers, and workspaceEnv are passed back to Che server and are used to define the sidecar that is added to the workspace.

At the moment, some of these fields (that are related to plugin viewer) are validated during the Plugin Registry dockerimage build.

CI

The following CentOS CI jobs are associated with the repository:

• master - builds CentOS images on each commit to the master branch and pushes them to quay.io.
• nightly - builds CentOS images and pushes them to quay.io on a daily basis from the master branch. The nightly version of the plugin registry is used by default by the nightly version of the Eclipse Che, which is also built on a daily basis by the all-che-docker-images-nightly CI job.
• release - builds CentOS and corresponding RHEL images from the release branch. CentOS images are public and pushed to quay.io. RHEL images are also pushed to quay.io, but to the private repositories and then used by the "Hosted Che" plugin registry - https://che-plugin-registry.openshift.io/.
• release-preview - builds CentOS and corresponding RHEL images from the release-preview branch and automatically updates "Hosted Che" staging plugin registry deployment based on the new version of images - https://che-plugin-registry.prod-preview.openshift.io/. CentOS images are public and pushed to quay.io. RHEL images are also pushed to quay.io, but to the private repositories.
