docker pull
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.
