Eclipse Che plugin registry

Build Eclipse Che plugin registry container image

Most of the time you won't need to rebuild the image because we build quay.io/eclipse/che-plugin-registry:nightly after every commit in master. In case you needed to change the content of the registry (e.g. add or modify some plugins meta.yaml) you can build your own image executing:

docker build --no-cache -t quay.io/eclipse/che-plugin-registry:nightly --target registry .

Where --no-cache is needed to prevent usage of cached layers with plugin registry files. Useful when you change plugin metadata files and rebuild the image.

Note that the Dockerfiles feature multi-stage build, so it requires Docker version 17.05 or higher.

Offline and airgapped registry images

It's possible to build an image for the plugin registry that includes all referenced extension artifacts (i.e. all .theia and .vsix archives). This is done using the same Dockerfile, but performs additional steps to download artifacts and rewrite the plugin meta.yamls to use files cached in v3/resources/.

docker build --no-cache -t quay.io/eclipse/che-plugin-registry:offline --target offline-registry .

Note that support for relative extensions was added in v0.20 of the plugin broker.

Run Eclipse Che plugin registry on OpenShift

You can deploy Che plugin registry on Openshift with command.

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

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 Eclipse Che plugin registry using Docker

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

    - https://github.com/Azure/vscode-kubernetes-tools/releases/download/0.1.17/vscode-kubernetes-tools-0.1.17.vsix # example
    - vscode:extension/redhat.vscode-xml # example
    - https://github.com/redhat-developer/omnisharp-theia-plugin/releases/download/v0.0.1/omnisharp_theia_plugin.theia # example
    - relative:extension/resources/java-0.46.0-1549.vsix # example; see [4]

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.
