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](/reference/commandline/run) section and the [Docker run reference](
|
||
|
/reference/run/) 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
|
||
|
drwxr-sr-x 5 1000 staff 180 Dec 5 04:00 .
|
||
|
