Procedure

An OpenShift template to deploy the plug-in registry is available in the openshift/ directory of the GitHub repository.

To deploy the plug-in registry using the OpenShift template, run the following command:

NAMESPACE=<namespace-name>  (1)
IMAGE_NAME="my-plug-in-registry"
IMAGE_TAG="latest"
oc new-app -f openshift/che-plugin-registry.yml \
 -n "$\{NAMESPACE}" \
 -p IMAGE="$\{IMAGE_NAME}" \
 -p IMAGE_TAG="$\{IMAGE_TAG}" \
 -p PULL_POLICY="IfNotPresent"

1	If installed using chectl, the default Che namespace is `default`. The OperatorHub installation method deploys Che to the users current namespace.

The devfile registry has an OpenShift template in the deploy/openshift/ directory of the GitHub repository. To deploy it, run the command:
```
NAMESPACE=<namespace-name>  (1)
IMAGE_NAME="my-devfile-registry"
IMAGE_TAG="latest"
oc new-app -f openshift/che-devfile-registry.yml \
 -n "$\{NAMESPACE}" \
 -p IMAGE="$\{IMAGE_NAME}" \
 -p IMAGE_TAG="$\{IMAGE_TAG}" \
 -p PULL_POLICY="IfNotPresent"
```
1 If installed using chectl, the default Che namespace is default. The OperatorHub installation method deploys Che to the users current namespace.

Check if the registries are deployed successfully on OpenShift.

To verify that the new plug-in is correctly published to the plug-in registry, make a request to the registry path /v3/plugins/index.json (or /devfiles/index.json for the devfile registry).

$ URL=$(oc get -o 'custom-columns=URL:.spec.rules[0].host' \
  -l app=che-plugin-registry route --no-headers)
$ INDEX_JSON=$(curl -sSL http://${URL}/v3/plugins/index.json)
$ echo ${INDEX_JSON} | grep -A 4 -B 5 "\"name\":\"my-plug-in\""

 "publisher":"my-org",
 "links": \{"self":"/v3/plugins/my-org/my-plug-in/latest" }
}

Verify that the Che server points to the URL of the registry. To do this, compare the value of the CHE_WORKSPACE_PLUGIN__REGISTRY__URL parameter in the che ConfigMap (or CHE_WORKSPACE_DEVFILE__REGISTRY__URL for the devfile registry):

$ oc get \
  -o "custom-columns=URL:.data['CHE_WORKSPACE_PLUGINREGISTRYURL']" \
  --no-headers cm/che
URL
http://che-plugin-registry-che.192.168.99.100.nip.io/v3

with the URL of the route:

$ oc get -o 'custom-columns=URL:.spec.rules[0].host' \
  -l app=che-plugin-registry route --no-headers
che-plugin-registry-che.192.168.99.100.nip.io

If they do not match, update the ConfigMap and restart the Che server.

$ oc edit cm/che
(...)
$ oc scale --replicas=0 deployment/che
$ oc scale --replicas=1 deployment/che

When the new registries are deployed and the Che server is configured to use them, the new plug-ins are available in the Plugin view of a workspace and the new stacks are displayed in the New Workspace tab of the user dashboard.
