Refer to the [`docker image tag`](tag.md) reference 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. Progress bars are shown during docker push, which show the uncompressed size. The actual amount of data that's pushed will be compressed before sending, so the uploaded size will not be reflected by the progress bar. Registry credentials are managed by [docker login](login.md). ### Concurrent uploads By default the Docker daemon will push five layers of an image at a time. If you are on a low bandwidth connection this may cause timeout issues and you may want to lower this via the `--max-concurrent-uploads` daemon option. See the [daemon documentation](dockerd.md) for more details. ## Examples ### Push a new image to a registry First save the new image by finding the container ID (using [`docker container ls`](ps.md)) and then committing it to a new image name. Note that only `a-z0-9-_.` are allowed when naming images: ```console $ docker container commit c16378f943fe rhel-httpd:latest ``` 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: ```console $ docker image tag rhel-httpd:latest registry-host:5000/myadmin/rhel-httpd:latest $ docker image push registry-host:5000/myadmin/rhel-httpd:latest ``` Check that this worked by running: ```console $ 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. ```console $ 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: ```console $ 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: ```console $ 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 ```
