OC ADM MIGRATE(1)

NAME

oc adm migrate image-references - Update embedded Docker image references

SYNOPSIS

oc adm migrate image-references [OPTIONS]

DESCRIPTION

Migrate references to Docker images

This command updates embedded Docker image references on the server in place. By default it will update image streams and images, and may be used to update resources with a pod template (deployments, replication controllers, daemon sets).

References are changed by providing a mapping between a source registry and name and the desired registry and name. Either name or registry can be set to ' *' to change all values. The registry value "docker.io" is special and will handle any image reference that refers to the DockerHub. You may pass multiple mappings - the first matching mapping will be applied per resource.

The following resource types may be migrated by this command:

    • buildconfigs

    • daemonsets

    • deploymentconfigs

    • images

    • imagestreams

    • jobs

    • pods

    • replicationcontrollers

    • secrets (docker)

Only images, imagestreams, and secrets are updated by default. Updating images and image streams requires administrative privileges.

OPTIONS

--all-namespaces=true
    Migrate objects in all namespaces. Defaults to true.

--confirm=false
    If true, all requested objects will be migrated. Defaults to false.

-f, --filename=[]
    Filename, directory, or URL to docker-compose.yml file to use

--from-key=""
    If specified, only migrate items with a key (namespace/name or name) greater than or equal to this value

--include=[imagestream,image,secrets]
    Resource types to migrate. Passing --filename will override this flag.

-o, --output=""
    Output the modified objects instead of saving them, valid values are 'yaml' or 'json'

--to-key=""
    If specified, only migrate items with a key (namespace/name or name) less than this value

--log-flush-frequency=0
    Maximum number of seconds between log flushes

--match-server-version=false
    Require server version to match client version

-n, --namespace=""
    If present, the namespace scope for this CLI request

--request-timeout="0"
    The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.

EXAMPLE

      # Perform a dry-run of migrating all "docker.io" references to "myregistry.com"
      oc adm migrate image-references docker.io/*=myregistry.com/*

      # To actually perform the migration, the confirm flag must be appended
      oc adm migrate image-references docker.io/*=myregistry.com/* --confirm

      # To see more details of what will be migrated, use the loglevel and output flags
      oc adm migrate image-references docker.io/*=myregistry.com/* --loglevel=2 -o yaml

      # Migrate from a service IP to an internal service DNS name
      oc adm migrate image-references 172.30.1.54/*=registry.openshift.svc.cluster.local/*

      # Migrate from a service IP to an internal service DNS name for all deployment configs and builds
      oc adm migrate image-references 172.30.1.54/*=registry.openshift.svc.cluster.local/* --include=buildconfigs,deploymentconfigs
