= Applying catalogs and Operators in a disconnected-deployment RHEL for Edge image
|
|
|
|
After you have created a {op-system-ostree} image for a disconnected environment and configured {microshift-short} networking settings for disconnected use, you can configure the namespace and create catalog and Operator custom resources (CR) for running your Operators.
|
|
|
|
.Prerequisites
|
|
* You have a {op-system-ostree} image.
|
|
* Networking is configured for disconnected use.
|
|
* You completed the oc-mirror plugin dry run procedure.
|
|
|
|
.Procedure
|
|
|
|
. Create a `CatalogSource` custom resource (CR), similar to the following example:
|
|
+
|
|
.Example `my-catalog-source-cr.yaml` file
|
|
[source,yaml]
|
|
----
|
|
apiVersion: operators.coreos.com/v1alpha1
|
|
kind: CatalogSource
|
|
metadata:
|
|
name: cs-redhat-operator-index
|
|
namespace: openshift-marketplace <1>
|
|
spec:
|
|
image: registry.example.com/redhat/redhat-operator-index:v4.16

sourceType: grpc

|
<1> The global namespace. Setting the `metadata.namespace` to `openshift-marketplace` enables the catalog to run in all namespaces. Subscriptions in any namespace can reference catalogs created in the `openshift-marketplace` namespace.
|
|
+
|
|
[NOTE]
|
|
====
|
|
The default pod security admission definition for `openshift-marketplace` is `baseline`, therefore a catalog source custom resource (CR) created in that namespace does not require a `spec.grpcPodConfig.securityContextConfig` value to be set. You can set a `legacy` or `restricted` value if required for the namespace and Operators you want to use.
|
|
====
|
|
|
|
. Add the SHA of the catalog index commit to the Catalog Source (CR), similar to the following example:
|
|
+
|
|
.Example namespace `spec.image` configuration

<1> The SHA of the image commit. Use the same SHA you added to the Image Builder blueprint.
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
You must use the SHA instead of a tag in your catalog CR or the pod fails to start.

. Apply the YAML file from the oc-mirror plugin dry run results directory to the cluster by running the following command:
|
|

|
|
[source,terminal]

----
|
|
$ oc apply -f ./oc-mirror-workspace/results-1708508014/catalogSource-cs-redhat-operator-index.yaml

----
|
|
$ oc get catalogsource --all-namespaces
