17 Migrate references to Docker images
18 This command updates embedded Docker image references on the server in
21 place. By default it will update image streams and images, and may be
22 used to update resources with a pod template (deployments, replication
23 controllers, daemon sets).
24 References are changed by providing a mapping between a source registry
27 and name and the desired registry and name. Either name or registry can
28 be set to ' *' to change all values. The registry value "docker.io" is
29 special and will handle any image reference that refers to the Docker‐
30 Hub. You may pass multiple mappings - the first matching mapping will
31 be applied per resource.
32 The following resource types may be migrated by this command:
35 · buildconfigs
37 · daemonsets
39 · deploymentconfigs
41 · images
43 · imagestreams
45 · jobs
47 · pods
49 · replicationcontrollers
51 · secrets (docker)
53 Only images, imagestreams, and secrets are updated by default. Updating
55 images and image streams requires administrative privileges.

61 Migrate objects in all namespaces. Defaults to true.
62 --allow-missing-template-keys=true
65 If true, ignore any errors in templates when a field or map key is

67 formats.
