Red Hat build of MicroShift

Create an image set configuration file

You must create an ImageSetConfiguration YAML file to specify both the Operators to mirror and the configuration settings for the oc-mirror plugin. Edit the contents of the file so that the entries are compatible with both MicroShift and the Operator you plan to use.

oc mirror v2 uses a cache system instead of metadata. The cache system prevents the need to start the entire mirroring process over when a single step fails. Instead, you can troubleshoot the failed step and the process does not re-mirror images that existed before the failure.

Prerequisites

You created a container image registry credentials file. For more information, see the following reference:
- Configuring credentials that allow images to be mirrored

Procedure

Create and edit the ImageSetConfiguration YAML for MicroShift by using the following example as a guide:
Example edited MicroShift image set configuration file
```
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v2alpha1
mirror:
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.20
    packages:
    - name: amq-broker-rhel9
      channels:
      - name: 7.13.x
  additionalImages:
   - name: quay.io/rh_ee_aguidi/multi-platform-container:latest
   - name: quay.io/rh_ee_aguidi/empty-image:latest
```
where:

mirror.operators.catalog

Specifies the Operator catalog to retrieve images from.

mirror.operators.packages.name

Specifies the Operator packages to include in the image set. Remove this field to retrieve all packages in the catalog.

mirror.operators.packages.channels.name

Specifies only certain channels of the Operator packages to include in the image set. You must always include the default channel for the Operator package even if you do not use the bundles in that channel. You can find the default channel by running the following command: oc mirror list operators --catalog=<catalog_name> --package=<package_name>.

mirror.additionalImages

Specifies any additional images to include in the image set. If you do not need to specify additional images, delete this field.

The platform field, related fields, and Helm are not supported by MicroShift.
Save the updated file as ImageSetConfiguration.yaml.

Next steps

Use the oc-mirror plugin to mirror an image set directly to a target mirror registry.
Configure CRI-O.
Apply the catalog sources to your node.
