oc-mirror is an OpenShift Client (oc) plugin that manages OpenShift release, operator catalog, helm charts, and associated container images for mirror registries that support OpenShift environments.

Please join us for our oc-mirror weekly community meeting Thursdays at 12pm EST https://zoom.us/j/99871298397?pwd=eHYrYlQxTDJaOTQ2bDl3VXlRMjFpUT09 . Retrieve the meeting passcode from the first comment in the following issue: openshift#349 .

The mirror registry reg.mirror.com is used in this example. Replace this value with a real registry host, or create a docker.io/library/registry:2 container locally.\

DISCLAIMER: oc-mirror is not compatible with Quay below version 3.6.

Example configurations can be found in the docs here

1. Download pull secret and place at ~/.docker/config.json¹.
   • Your mirror registry secret must have both push and pull scopes.
2. Build:

   make build

IMPORTANT: Backends must be configured to utilize the lifecycle management features of oc-mirror. Examples are below.

apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
archiveSize: 1
storageConfig:
  local:
    path: /home/user/workspace

apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
storageConfig:
  registry:
    imageURL: localhost:5000/metadata:latest
    skipTLS: true

• List updates since the last oc-mirror run

  ./bin/oc-mirror list updates --config imageset-config.yaml

1. List all available release payloads for a version of OpenShift (defaults to stable)

   ./bin/oc-mirror list releases --version=4.9

2. List all available channels to query for a version of OpenShift

   ./bin/oc-mirror list releases --channels --version=4.9

3. List all available release payloads for a version of OpenShift in a specified channel

   ./bin/oc-mirror list releases --channel=fast-4.9

1. List all available catalogs for a version of OpenShift

   ./bin/oc-mirror list operators --catalogs --version=4.9

2. List all available packages in a catalog

   ./bin/oc-mirror list operators --catalog=catalog-name

3. List all available channels in a package

   ./bin/oc-mirror list operators --catalog=catalog-name --package=package-name

4. List all available versions in a channel

   ./bin/oc-mirror list operators --catalog=catalog-name --package=package-name --channel=channel-name

• Create then publish to your mirror registry:

  ./bin/oc-mirror --config imageset-config.yaml file://archives
  ./bin/oc-mirror --from /path/to/archives docker://reg.mirror.com

• Publish mirror to mirror

  ./bin/oc-mirror --config imageset-config.yaml docker://localhost:5000

• Get information on your imageset using describe

  ./bin/oc-mirror describe /path/to/archives

• List updates since last run for releases and operators

  ./bin/oc-mirror list updates --config imageset-config.yaml

For configuration and options, see the expanded overview and usage docs.

¹ For this example, the create and publish steps are run on the same machine. Therefore your ~/.docker/config.json or ${XDG_RUNTIME_DIR}/containers/auth.json should contain auth config for both release/catalog source images and your mirror registry.

See the config spec for an in-depth description of fields.

Note: The imageset-config.yaml is only used during bundle creation.
