oc-set-image-lookup - Man Page
Change how images are resolved when deploying applications
Synopsis
oc set image-lookup [Options]
Description
Use an image stream from pods and other objects
Image streams make it easy to tag images, track changes from other registries, and centralize access control to images. Local name lookup allows an image stream to be the source of images for pods, deployments, replica sets, and other resources that reference images, without having to provide the full registry URL. If local name lookup is enabled for an image stream named 'mysql', a pod or other resource that references 'mysql:latest' (or any other tag) will pull from the location specified by the image stream tag, not from an upstream registry.
Once lookup is enabled, simply reference the image stream tag in the image field of the object. For example:
$ oc import-image mysql:latest --confirm $ oc set image-lookup mysql $ oc run mysql --image=mysql
will import the latest MySQL image from the DockerHub, set that image stream to handle the "mysql" name within the project, and then launch a deployment that points to the image we imported.
You may also force image lookup for all of the images on a resource with this command. An annotation is placed on the object which forces an image stream tag lookup in the current namespace for any image that matches, regardless of whether the image stream has lookup enabled.
$ oc run mysql --image=myregistry:5000/test/mysql:v1 $ oc tag --source=docker myregistry:5000/test/mysql:v1 mysql:v1 $ oc set image-lookup deploy/mysql
Which should trigger a deployment pointing to the imported mysql:v1 tag.
Experimental: This feature is under active development and may change without notice.
