12.4.17.2.2. Configuring storage for the image registry in non-production clusters

You must configure storage for the Image Registry Operator. For non-production clusters, you can set the image registry to an empty directory. If you do so, all images are lost if you restart the registry.

Procedure

  1. To set the image registry storage to an empty directory: 

    $ oc patch configs.imageregistry.operator.openshift.io cluster --type merge --patch '{"spec":{"storage":{"emptyDir":{}}}}'
    警告

    Configure this option for only non-production clusters.

    If you run this command before the Image Registry Operator initializes its components, the oc patch command fails with the following error: 

    Error from server (NotFound): configs.imageregistry.operator.openshift.io "cluster" not found

    Wait a few minutes and run the command again.

  2. Ensure that your registry is set to managed to enable building and pushing of images.

    • Run: 

      $ oc edit configs.imageregistry/cluster

      Then, change the line 

      managementState: Removed

      to 

      managementState: Managed
