Usage: docker pull [OPTIONS] NAME[:TAG] | [REGISTRY_HOST[:REGISTRY_PORT]/]NAME[:TAG]
Pull an image or a repository from the registry -a, --all-tags=false Download all tagged images in the repository --disable-content-trust=true Skip image verification
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
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),
$ 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
docker pull -a and
--disable-content-trust=true are currently unsupported.

The first status line from a
docker pull shows a UUID:
$ docker pull busybox latest: Pulling from busybox (67c12cfb-f717-4bc6-b3a9-b558becf4bbb) ...
That UUID is an "request id" for the pull. It can be useful for auditing and internal debugging of sdc-docker.
