How do i tag a docker image?



  • Man page for docker tag: http://bit.ly/2lUQFOm
    Man page for docker image ls: http://bit.ly/2j3PXxc

    Tagging makes things easy to search and identify them from other images.

    To tag a docker image, run the following command. The /env/dev/zookeeper, is part of the registry path, the 3.3.6 is the tag.

    $ docker tag zookeeper localhost:5000/env/dev/zookeeper:3.3.6
    

    Run a docker image list. "docker image list" does the same. Here you can see the registry and the tag

    $ docker image ls
    REPOSITORY                         TAG                 IMAGE ID            CREATED             SIZE
    zookeeper                          latest              c22925343447        44 hours ago        144MB

    registry                           2                   a07e3f32a779        15 days ago          33.3MB
