# push ```markdown Usage: docker push [OPTIONS] NAME[:TAG] Push an image or a repository to a registry Options: --disable-content-trust Skip image verification (default true) --help Print usage ``` Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com) registry or to a self-hosted one. Refer to the [`docker tag`](tag.md) reference for more information about valid image and tag names. Killing the `docker 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](login.md). ## EXAMPLES ### Pushing a new image to a registry First save the new image by finding the container ID (using [`docker ps`](ps.md)) and then committing it to a new image name. Note that only `a-z0-9-_.` are allowed when naming images: ```bash $ docker 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: ```bash $ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd $ docker push registry-host:5000/myadmin/rhel-httpd ``` Check that this worked by running: ```bash $ docker images ``` You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd` listed.
