pull

Usage: docker pull [OPTIONS] NAME[:TAG] | [REGISTRY_HOST[:REGISTRY_PORT]/]NAME[:TAG]

Pull an image or a repository from the registry

  -a, --all-tags                Download all tagged images in the repository
  --disable-content-trust=true  Skip image verification
  --help                        Print usage

Most of your images will be created on top of a base image from the Docker Hub registry.

Docker Hub contains many pre-built images that you can pull and try without needing to define and configure your own.

It is also possible to manually specify the path of a registry to pull from. For example, if you have set up a local registry, you can specify its path to pull from it. A repository path is similar to a URL, but does not contain a protocol specifier (https://, for example).

To download a particular image, or set of images (i.e., a repository), use docker pull:

$ docker pull debian
# will pull the debian:latest image and its intermediate layers
$ docker pull debian:testing
# will pull the image named debian:testing and any intermediate
# layers it is based on.
$ docker pull debian@sha256:cbbf2f9a99b47fc460d422812b6a5adff7dfee951d8fa2e4a98caa0382cfbdbf
# will pull the image from the debian repository with the digest
# sha256:cbbf2f9a99b47fc460d422812b6a5adff7dfee951d8fa2e4a98caa0382cfbdbf
# and any intermediate layers it is based on.
# (Typically the empty `scratch` image, a MAINTAINER layer,
# and the un-tarred base).
$ docker pull --all-tags centos
# will pull all the images from the centos repository
$ docker pull registry.hub.docker.com/debian
# manually specifies the path to the default Docker registry. This could
# be replaced with the path to a local registry to pull from another source.
# sudo docker pull myhub.com:8080/test-image

Killing the docker pull process, for example by pressing CTRL-c while it is running in a terminal, will terminate the pull operation.
