14.2. Starting a Container
Execute the following steps to start the container.
- Execute the following command to run the container:
docker run -d --privileged=true --net=host --name <container-name> -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z <image name>
# docker run -d --privileged=true --net=host --name <container-name> -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z <image name>Copy to Clipboard Copied!

/mnt/brick1is the mountpoint of the brick in the atomic host and:/mnt/container_brick1is the mountpoint of the brick in the container.- -d option starts the container in the detached mode.
For example:docker run -d --privileged=true --net=host --name glusternode1 -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z rhgs3/rhgs-server-rhel7
# docker run -d --privileged=true --net=host --name glusternode1 -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z rhgs3/rhgs-server-rhel7 5ac864b5abc74a925aecc4fe9613c73e83b8c54a846c36107aa8e2960eeb97b4Copy to Clipboard Copied!

- SELinux labels are automatically reset to
svirt_sandbox_file_tso that the container can interact with the Atomic Host directory. - In the above command, the following ensures that the gluster configuration are persistent.
-v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd -v /var/log/glusterfs:/var/log/glusterfs
-v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd -v /var/log/glusterfs:/var/log/glusterfsCopy to Clipboard Copied! Toggle word wrap Toggle overflow
- If you want to use snapshot then execute the following command:
docker run -d --privileged=true --net=host --name <container-name> -v /dev:/dev -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z <image name>
# docker run -d --privileged=true --net=host --name <container-name> -v /dev:/dev -v /run -v /etc/glusterfs:/etc/glusterfs:z -v /var/lib/glusterd:/var/lib/glusterd:z -v /var/log/glusterfs:/var/log/glusterfs:z -v /sys/fs/cgroup:/sys/fs/cgroup:ro -v /mnt/brick1:/mnt/container_brick1:z <image name>Copy to Clipboard Copied!
