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


oc adm migrate image-references [Options]


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.



Migrate objects in all namespaces. Defaults to true.


If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.


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

-f, --filename=[]

Filename, directory, or URL to docker-compose.yml file to use


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


Resource types to migrate. Passing --filename will override this flag.


When using the default or custom-column output format, don't print headers (default print headers).

-o, --output=""

Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [ ⟨http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns⟩], golang template [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩] and jsonpath template [ ⟨http://kubernetes.io/docs/user-guide/jsonpath⟩].

-a, --show-all=true

When printing, show all resources (false means hide terminated pods.)


When printing, show all labels as the last column (default hide labels column)


If non-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.


Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩].


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

Options Inherited from Parent Commands


Username to impersonate for the operation


Group to impersonate for the operation, this flag can be repeated to specify multiple groups.


Path to the file container Azure container registry configuration information.


Default HTTP cache directory


Path to a cert file for the certificate authority


Path to a client certificate file for TLS


Path to a client key file for TLS


The name of the kubeconfig cluster to use


Path to the config file to use for CLI requests.


The name of the kubeconfig context to use


The Google Cloud Platform Service Account JSON Key to use for authentication.


If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure


Require server version to match client version

-n, --namespace=""

If present, the namespace scope for this CLI request


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.


The address and port of the Kubernetes API server


Bearer token for authentication to the API server


The name of the kubeconfig user to use


Print version information and quit
