Update help line to allow 90 characters instead of 80 The trust flag pushes out the help description column wider, requiring more room to display help messages. Signed-off-by: Derek McGowan <derek@mcgstyle.net> (github: dmcgowan)

# 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=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](https://hub.docker.com) registry.
|
|
|
|
[Docker Hub](https://hub.docker.com) 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
