Catalog selection by name

When a catalog is added to a cluster, a label is created by using the value of the metadata.name field of the catalog custom resource (CR). In the CR of an extension, you can specify the catalog name by using the spec.source.catalog.selector.matchLabels field.

The value of the matchLabels field uses the following format:

Example label derived from the metadata.name field

apiVersion: olm.operatorframework.io/v1
kind: ClusterExtension
metadata:
  name: <example_extension>
  labels:
    olm.operatorframework.io/metadata.name: <example_extension>
...

The <example_extension> value is the label derived from the metadata.name field and automatically added when the catalog is applied.

The following example resolves the <example_extension>-operator package from a catalog with the openshift-redhat-operators label:

Example extension CR

apiVersion: olm.operatorframework.io/v1
kind: ClusterExtension
metadata:
  name: <example_extension>
spec:
  namespace: <example_namespace>
  serviceAccount:
    name: <example_extension>-installer
  source:
    sourceType: Catalog
    catalog:
      packageName: <example_extension>-operator
      selector:
        matchLabels:
          olm.operatorframework.io/metadata.name: openshift-redhat-operators
