Add a --readonly flag to allow the container's root filesystem to be mounted as readonly. This can be used in combination with volumes to force a container's process to only write to locations that will be persisted. This is useful in many cases where the admin controls where they would like developers to write files and error on any other locations.

NAME
docker-create - Create a new container
SYNOPSIS
docker create [-a|--attach[=[]]] [--add-host[=[]]] [-c|--cpu-shares[=0]] [--cap-add[=[]]] [--cap-drop[=[]]] [--cidfile[=CIDFILE]] [--cpuset[=CPUSET]] [--device[=[]]] [--dns-search[=[]]] [--dns[=[]]] [-e|--env[=[]]] [--entrypoint[=ENTRYPOINT]] [--env-file[=[]]] [--expose[=[]]] [-h|--hostname[=HOSTNAME]] [--help] [-i|--interactive[=false]] [--ipc[=IPC]] [--link[=[]]] [--lxc-conf[=[]]] [-m|--memory[=MEMORY]] [--mac-address[=MAC-ADDRESS]] [--name[=NAME]] [--net[="bridge"]] [-P|--publish-all[=false]] [-p|--publish[=[]]] [--pid[=[]]] [--privileged[=false]] [--read-only[=false]] [--restart[=RESTART]] [--security-opt[=[]]] [-t|--tty[=false]] [-u|--user[=USER]] [-v|--volume[=[]]] [--volumes-from[=[]]] [-w|--workdir[=WORKDIR]] IMAGE [COMMAND] [ARG...]
OPTIONS
-a, --attach=[] Attach to STDIN, STDOUT or STDERR.
--add-host=[] Add a custom host-to-IP mapping (host:ip)
-c, --cpu-shares=0 CPU shares (relative weight)
--cap-add=[] Add Linux capabilities
--cap-drop=[] Drop Linux capabilities
--cidfile="" Write the container ID to the file
--cpuset="" CPUs in which to allow execution (0-3, 0,1)
--device=[] Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc:rwm)
--dns-search=[] Set custom DNS search domains (Use --dns-search=. if you don't wish to set the search domain)
--dns=[] Set custom DNS servers
-e, --env=[] Set environment variables
--entrypoint="" Overwrite the default ENTRYPOINT of the image
--env-file=[] Read in a line delimited file of environment variables
--expose=[] Expose a port or a range of ports (e.g. --expose=3300-3310) from the container without publishing it to your host
-h, --hostname="" Container host name
--help Print usage statement
-i, --interactive=true|false Keep STDIN open even if not attached. The default is false.
--ipc="" Default is to create a private IPC namespace (POSIX SysV IPC) for the container 'container:<name|id>': reuses another container shared memory, semaphores and message queues 'host': use the host shared memory,semaphores and message queues inside the container. Note: the host mode gives the container full access to local shared memory and is therefore considered insecure.
--link=[] Add link to another container in the form of name:alias
--lxc-conf=[] (lxc exec-driver only) Add custom lxc options --lxc-conf="lxc.cgroup.cpuset.cpus = 0,1"
-m, --memory="" Memory limit (format: , where unit = b, k, m or g)
--mac-address="" Container MAC address (e.g. 92:d0:c6:0a:29:33)
--name="" Assign a name to the container
--net="bridge" Set the Network mode for the container 'bridge': creates a new network stack for the container on the docker bridge 'none': no networking for this container 'container:<name|id>': reuses another container network stack 'host': use the host network stack inside the container. Note: the host mode gives the container full access to local system services such as D-bus and is therefore considered insecure.
-P, --publish-all=true|false Publish all exposed ports to random ports on the host interfaces. The default is false.
-p, --publish=[]
Publish a container's port, or a range of ports, to the host
format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort
Both hostPort and containerPort can be specified as a range of ports.
When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range. (e.g., -p 1234-1236:1234-1236/tcp)
(use 'docker port' to see the actual mapping)
--pid=host Set the PID mode for the container host: use the host's PID namespace inside the container. Note: the host mode gives the container full access to local PID and is therefore considered insecure.
--privileged=true|false Give extended privileges to this container. The default is false.
--read-only=true|false Mount the container's root filesystem as read only.
--restart="" Restart policy to apply when a container exits (no, on-failure[:max-retry], always)
--security-opt=[] Security Options
-t, --tty=true|false Allocate a pseudo-TTY. The default is false.
-u, --user="" Username or UID
-v, --volume=[] Bind mount a volume (e.g., from the host: -v /host:/container, from Docker: -v /container)
--volumes-from=[] Mount volumes from the specified container(s)
-w, --workdir="" Working directory inside the container
