The 122 container ID is then printed to `STDOUT`. This is similar to `docker run -d` 123 except the container is never started. You can then use the 124 `docker start <container_id>` command to start the container at any point. 125 126 This is useful when you want to set up a container configuration ahead of time 127 so that it is ready to start when you need it. The initial status of the 128 new container is `created`. 129 130 Please see the [run command](run.md) section and the [Docker run reference](../run.md) for more details. 131 132 ## Examples 133 134 $ docker create -t -i fedora bash 135 6d8af538ec541dd581ebc2a24153a28329acb5268abe5ef868c1f1a261221752 136 $ docker start -a -i 6d8af538ec5 137 bash-4.2# 138 139 As of v1.4.0 container volumes are initialized during the `docker create` phase 140 (i.e., `docker run` too). For example, this allows you to `create` the `data` 141 volume container, and then use it from another container: 142 143 $ docker create -v /data --name data ubuntu 144 240633dfbb98128fa77473d3d9018f6123b99c454b3251427ae190a7d951ad57 145 $ docker run --rm --volumes-from data ubuntu ls -la /data 146 total 8 147 drwxr-xr-x 2 root root 4096 Dec 5 04:10 . 148 drwxr-xr-x 48 root root 4096 Dec 5 04:11 .. 149 150 Similarly, `create` a host directory bind mounted volume container, which can 151 then be used from the subsequent container: 152 153 $ docker create -v /home/docker:/docker --name docker ubuntu 154 9aa88c08f319cd1e4515c3c46b0de7cc9aa75e878357b1e96f91e2c773029f03 155 $ docker run --rm --volumes-from docker ubuntu ls -la /docker 156 total 20 157 drwxr-sr-x 5 1000 staff 180 Dec 5 04:00 . 158 drwxr-xr-x 48 root root 4096 Dec 5 04:13 .. 159 -rw-rw-r-- 1 1000 staff 3833 Dec 5 04:01 .ash_history 160 -rw-r--r-- 1 1000 staff 446 Nov 28 11:51 .ashrc 161 -rw-r--r-- 1 1000 staff 25 Dec 5 04:00 .gitconfig 162 drwxr-sr-x 3 1000 staff 60 Dec 1 03:28 .local 163 -rw-r--r-- 1 1000 staff 920 Nov 28 11:51 .profile 164 drwx--S--- 2 1000 staff 460 Dec 5 00:51 .ssh 165 drwxr-xr-x 32 1000 staff 1140 Dec 5 04:01 docker 166 167 Set storage driver options per container. 168 169 $ docker create -it --storage-opt size=120G fedora /bin/bash 170 171 This (size) will allow to set the container rootfs size to 120G at creation time. 172 User cannot pass a size less than the Default BaseFS Size. This option is only 173 available for the `devicemapper`, `btrfs`, `windowsfilter`, and `zfs` graph drivers. 174 175 ### Specify isolation technology for container (--isolation) 176 177 This option is useful in situations where you are running Docker containers on 178 Windows. The `--isolation=<value>` option sets a container's isolation 179 technology. On Linux, the only supported is the `default` option which uses 180 Linux namespaces. On Microsoft Windows, you can specify these values: 181 182 183 | Value | Description | 184 |-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------| 185 | `default` | Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value if the 186 daemon is running on Windows server, or `hyperv` if running on Windows client. | 187 | `process` | Namespace isolation only. | 188 | `hyperv` | Hyper-V hypervisor partition-based isolation. | 189 190 Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.
