The 74 container ID is then printed to `STDOUT`. This is similar to `docker run -d` 75 except the container is never started. You can then use the 76 `docker start <container_id>` command to start the container at any point. 77 78 This is useful when you want to set up a container configuration ahead of time 79 so that it is ready to start when you need it. The initial status of the 80 new container is `created`. 81 82 Please see the [run command](/reference/commandline/run) section and the [Docker run reference]( 83 /reference/run/) for more details. 84 85 ## Examples 86 87 $ docker create -t -i fedora bash 88 6d8af538ec541dd581ebc2a24153a28329acb5268abe5ef868c1f1a261221752 89 $ docker start -a -i 6d8af538ec5 90 bash-4.2# 91 92 As of v1.4.0 container volumes are initialized during the `docker create` phase 93 (i.e., `docker run` too). For example, this allows you to `create` the `data` 94 volume container, and then use it from another container: 95 96 $ docker create -v /data --name data ubuntu 97 240633dfbb98128fa77473d3d9018f6123b99c454b3251427ae190a7d951ad57 98 $ docker run --rm --volumes-from data ubuntu ls -la /data 99 total 8 100 drwxr-xr-x 2 root root 4096 Dec 5 04:10 . 101 drwxr-xr-x 48 root root 4096 Dec 5 04:11 .. 102 103 Similarly, `create` a host directory bind mounted volume container, which can 104 then be used from the subsequent container: 105 106 $ docker create -v /home/docker:/docker --name docker ubuntu 107 9aa88c08f319cd1e4515c3c46b0de7cc9aa75e878357b1e96f91e2c773029f03 108 $ docker run --rm --volumes-from docker ubuntu ls -la /docker 109 total 20 110 drwxr-sr-x 5 1000 staff 180 Dec 5 04:00 . 111 drwxr-xr-x 48 root root 4096 Dec 5 04:13 .. 112 -rw-rw-r-- 1 1000 staff 3833 Dec 5 04:01 .ash_history 113 -rw-r--r-- 1 1000 staff 446 Nov 28 11:51 .ashrc 114 -rw-r--r-- 1 1000 staff 25 Dec 5 04:00 .gitconfig 115 drwxr-sr-x 3 1000 staff 60 Dec 1 03:28 .local 116 -rw-r--r-- 1 1000 staff 920 Nov 28 11:51 .profile 117 drwx--S--- 2 1000 staff 460 Dec 5 00:51 .ssh 118 drwxr-xr-x 32 1000 staff 1140 Dec 5 04:01 docker 119 120
