5.2. Managing cluster extensions

Procedure

1. To return a list of extensions that support the AllNamespaces install mode and do not use webhooks, enter the following command:

   $ opm render <catalog_registry_url>:<tag> \
     | jq -cs '[.[] | select(.schema == "olm.bundle" \
     and (.properties[] | select(.type == "olm.csv.metadata").value.installModes[] \
     | select(.type == "AllNamespaces" and .supported == true)) \
     and .spec.webhookdefinitions == null) | .package] | unique[]'

   where:

   catalog_registry_url

   Specifies the URL of the catalog registry, such as registry.redhat.io/redhat/redhat-operator-index.

   tag

   Specifies the tag or version of the catalog, such as v4.21 or latest.

   例 5.1. Example command

   $ opm render \
     registry.redhat.io/redhat/redhat-operator-index:v4.21 \
     | jq -cs '[.[] | select(.schema == "olm.bundle" \
     and (.properties[] | select(.type == "olm.csv.metadata").value.installModes[] \
     | select(.type == "AllNamespaces" and .supported == true)) \
     and .spec.webhookdefinitions == null) | .package] | unique[]'

   例 5.2. Example output

   "3scale-operator"
   "amq-broker-rhel8"
   "amq-online"
   "amq-streams"
   "amq-streams-console"
   "ansible-automation-platform-operator"
   "ansible-cloud-addons-operator"
   "apicast-operator"
   "authorino-operator"
   "aws-load-balancer-operator"
   "bamoe-kogito-operator"
   "cephcsi-operator"
   "cincinnati-operator"
   "cluster-logging"
   "cluster-observability-operator"
   "compliance-operator"
   "container-security-operator"
   "cryostat-operator"
   "datagrid"
   "devspaces"
   ...

2. Inspect the contents of an extension’s metadata by running the following command:

   $ opm render <catalog_registry_url>:<tag> \
     | jq -s '.[] | select( .schema == "olm.package") \
     | select( .name == "<package_name>")'

   例 5.3. Example command

   $ opm render \
     registry.redhat.io/redhat/redhat-operator-index:v4.21 \
     | jq -s '.[] | select( .schema == "olm.package") \
     | select( .name == "openshift-pipelines-operator-rh")'

   例 5.4. Example output

   {
     "schema": "olm.package",
     "name": "openshift-pipelines-operator-rh",
     "defaultChannel": "latest",
     "icon": {
       "base64data": "iVBORw0KGgoAAAANSUhE...",
       "mediatype": "image/png"
     }
