NAME

       docker-image-push - Upload an image to a registry

SYNOPSIS

       docker image push [OPTIONS] NAME[:TAG]

DESCRIPTION

       Use  docker  image  push  to  share your images to the Docker Hub ⟨https://hub.docker.com⟩
       registry or to a self-hosted one.

       Refer to docker-image-tag(1) for more information about valid image and tag names.

       Killing the docker image push process, for example by pressing CTRL-c while it is  running
       in a terminal, terminates the push operation.

       Registry credentials are managed by docker-login(1).

EXAMPLES

Pushing a new image to a registry

       First  save the new image by finding the container ID (using docker container ls) and then
       committing it to a new image name.  Note that  only  a-z0-9-_.  are  allowed  when  naming
       images:

              # docker container commit c16378f943fe rhel-httpd

       Now, push the image to the registry using the image ID. In this example the registry is on
       host named registry-host and listening on port 5000. To do this, tag the  image  with  the
       host name or IP address, and the port of the registry:

              # docker image tag rhel-httpd registry-host:5000/myadmin/rhel-httpd:latest
              # docker image push registry-host:5000/myadmin/rhel-httpd:latest

       Check that this worked by running:

              # docker image ls

       You should see both rhel-httpd and registry-host:5000/myadmin/rhel-httpd listed.

   Push all tags of an image
       Use the -a (or --all-tags) option to push all tags of a local image.

       The  following  example  creates  multiple tags for an image, and pushes all those tags to
       Docker Hub.

              $ docker image tag myimage registry-host:5000/myname/myimage:latest
              $ docker image tag myimage registry-host:5000/myname/myimage:v1.0.1
              $ docker image tag myimage registry-host:5000/myname/myimage:v1.0
              $ docker image tag myimage registry-host:5000/myname/myimage:v1

       The image is now tagged under multiple names:

              $ docker image ls

              REPOSITORY                          TAG        IMAGE ID       CREATED      SIZE
              myimage                             latest     6d5fcfe5ff17   2 hours ago  1.22MB
              registry-host:5000/myname/myimage   latest     6d5fcfe5ff17   2 hours ago  1.22MB
              registry-host:5000/myname/myimage   v1         6d5fcfe5ff17   2 hours ago  1.22MB
              registry-host:5000/myname/myimage   v1.0       6d5fcfe5ff17   2 hours ago  1.22MB
              registry-host:5000/myname/myimage   v1.0.1     6d5fcfe5ff17   2 hours ago  1.22MB

       When pushing with the --all-tags option, all tags of the registry-host:5000/myname/myimage
       image are pushed:

              $ docker image push --all-tags registry-host:5000/myname/myimage

              The push refers to repository [registry-host:5000/myname/myimage]
