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]
