4.8. Tagging images

Procedure

1. List all images:

   $ podman images
   REPOSITORY                           TAG     IMAGE ID      CREATED      SIZE
   registry.redhat.io/ubi10/ubi          latest  3269c37eae33  7 weeks ago  208 MB

2. Assign the myubi name to the registry.redhat.io/ubi10/ubi image using one of the following options:

   • The image name:

     $ podman tag registry.redhat.io/ubi10/ubi myubi

   • The image ID:

     $ podman tag 3269c37eae33 myubi

     Both commands give you the same result.

3. List all images:

   $ podman images
   REPOSITORY                           TAG     IMAGE ID      CREATED       SIZE
   registry.redhat.io/ubi10/ubi          latest  3269c37eae33  2 months ago  208 MB
   localhost/myubi                      latest  3269c37eae33  2 months ago  208 MB

   Notice that the default tag is latest for both images. You can see all the image names are assigned to the single image ID 3269c37eae33.

4. Add the 10 tag to the registry.redhat.io/ubi10/ubi image using either:

   • The image name:

     $ podman tag registry.redhat.io/ubi10/ubi myubi:10

   • The image ID:

     $ podman tag 3269c37eae33 myubi:10

     Both commands give you the same result.
