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] 195be5f8be1d: Pushed latest: digest: sha256:edafc0a0fb057813850d1ba44014914ca02d671ae247107ca70c94db686e7de6 size: 4527 195be5f8be1d: Layer already exists v1: digest: sha256:edafc0a0fb057813850d1ba44014914ca02d671ae247107ca70c94db686e7de6 size: 4527 195be5f8be1d: Layer already exists v1.0: digest: sha256:edafc0a0fb057813850d1ba44014914ca02d671ae247107ca70c94db686e7de6 size: 4527 195be5f8be1d: Layer already exists v1.0.1: digest: sha256:edafc0a0fb057813850d1ba44014914ca02d671ae247107ca70c94db686e7de6 size: 4527
