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]
