The docker create command creates a writeable container layer over the
specified image and prepares it for running the specified command. The
container ID is then printed to STDOUT. This is similar to docker run -d
except the container is never started. You can then use the
docker start <container_id> command to start the container at any point.
This is useful when you want to set up a container configuration ahead of time
so that it is ready to start when you need it. The initial status of the
new container is created.
Please see the run command section and the Docker run reference for more details.
Examples
$ docker create -t -i fedora bash
6d8af538ec541dd581ebc2a24153a28329acb5268abe5ef868c1f1a261221752
$ docker start -a -i 6d8af538ec5
bash-4.2#
As of v1.4.0 container volumes are initialized during the docker create phase
(i.e., docker run too). For example, this allows you to create the data
volume container, and then use it from another container:
$ docker create -v /data --name data ubuntu
240633dfbb98128fa77473d3d9018f6123b99c454b3251427ae190a7d951ad57
$ docker run --rm --volumes-from data ubuntu ls -la /data
total 8
drwxr-xr-x 2 root root 4096 Dec 5 04:10 .
drwxr-xr-x 48 root root 4096 Dec 5 04:11 ..
Similarly, create a host directory bind mounted volume container, which can
then be used from the subsequent container:
$ docker create -v /home/docker:/docker --name docker ubuntu
9aa88c08f319cd1e4515c3c46b0de7cc9aa75e878357b1e96f91e2c773029f03
$ docker run --rm --volumes-from docker ubuntu ls -la /docker
total 20
