    Skopeo is a command line tool for working with remote image registries.

    Skopeo doesn’t require a daemon to be running while performing its operations.
    In particular, the handy skopeo command called copy will ease the whole image
    copy operation. The copy command will take care of copying the image from
    internal.registry to production.registry. If your production registry requires
    credentials to login in order to push the image, skopeo can handle that as well.

  workspaces:
    - name: images-url
  params:
    - name: srcImageURL
      description: URL of the image to be copied to the destination registry
      type: string
      default: ""
    - name: destImageURL
      description: URL of the image where the image from source should be copied to
      type: string
      default: ""
    - name: srcTLSverify
      description: Verify the TLS on the src registry endpoint
      type: string
      default: "true"
    - name: destTLSverify
      description: Verify the TLS on the dest registry endpoint
      type: string
      default: "true"
