Create an Image Stream
Create an Individual Image Stream with import-image
This command fetches the latest version of an image from a remote repository and updates the image stream tag if it does not match the previous value. It is idempotent, running the command multiple times will not create duplicate entries. When importing an image, only the image metadata is copied, not the image contents. If the image stream does not exist, the image stream is created if --confirm is provided.
oc import-image <imagestream-name>[:tag] \ --from <registry/image> [--confirm]
oc import-image local-redhat-openjdk-18/openjdk18-openshift \ --from=registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift --confirm
Import Image Streams in Bulk
The following procedure will create a set of image streams in the "openshift" project. An example of image stream definition file is available at https://raw.githubusercontent.com/jboss-openshift/application-templates/master/jboss-image-streams.json. A version is also available here: OpenShift JBoss ImageStream Definition Example.
oc login -u system:admin oc create -f ./jboss-image-streams.json -n openshift
The output is similar to:
