The 78 container ID is then printed to `STDOUT`. This is similar to `docker run -d` 79 except the container is never started. You can then use the 80 `docker start <container_id>` command to start the container at any point. 81 82 This is useful when you want to set up a container configuration ahead of time 83 so that it is ready to start when you need it. The initial status of the 84 new container is `created`. 85 86 Please see the [run command](run.md) section and the [Docker run reference](run.md) for more details. 87 88 ## Examples 89 90 $ docker create -t -i fedora bash 91 6d8af538ec541dd581ebc2a24153a28329acb5268abe5ef868c1f1a261221752 92 $ docker start -a -i 6d8af538ec5 93 bash-4.2# 94 95 As of v1.4.0 container volumes are initialized during the `docker create` phase 96 (i.e., `docker run` too). For example, this allows you to `create` the `data` 97 volume container, and then use it from another container: 98 99 $ docker create -v /data --name data ubuntu 100 240633dfbb98128fa77473d3d9018f6123b99c454b3251427ae190a7d951ad57 101 $ docker run --rm --volumes-from data ubuntu ls -la /data 102 total 8 103 drwxr-xr-x 2 root root 4096 Dec 5 04:10 . 104 drwxr-xr-x 48 root root 4096 Dec 5 04:11 .. 105 106 Similarly, `create` a host directory bind mounted volume container, which can 107 then be used from the subsequent container: 108 109 $ docker create -v /home/docker:/docker --name docker ubuntu 110 9aa88c08f319cd1e4515c3c46b0de7cc9aa75e878357b1e96f91e2c773029f03 111 $ docker run --rm --volumes-from docker ubuntu ls -la /docker 112 total 20 113 drwxr-sr-x 5 1000 staff 180 Dec 5 04:00 . 114 drwxr-xr-x 48 root root 4096 Dec 5 04:13 .. 115 -rw-rw-r-- 1 1000 staff 3833 Dec 5 04:01 .ash_history 116 -rw-r--r-- 1 1000 staff 446 Nov 28 11:51 .ashrc 117 -rw-r--r-- 1 1000 staff 25 Dec 5 04:00 .gitconfig 118 drwxr-sr-x 3 1000 staff 60 Dec 1 03:28 .local 119 -rw-r--r-- 1 1000 staff 920 Nov 28 11:51 .profile 120 drwx--S--- 2 1000 staff 460 Dec 5 00:51 .ssh 121 drwxr-xr-x 32 1000 staff 1140 Dec 5 04:01 docker
