Run a process in a running container.
|
|
|
|
The command started using `docker exec` will only run while the container's primary
|
|
process (`PID 1`) is running, and will not be restarted if the container is restarted.
|
|
|
|
If the container is paused, then the `docker exec` command will wait until the
|
|
container is unpaused, and then run
|
|
|
|
# CAPABILITIES
|
|
|
|
`privileged` gives the process extended
|
|
[Linux capabilities](http://man7.org/linux/man-pages/man7/capabilities.7.html)
|
|
when running in a container.
|
|
|
|
Without this flag, the process run by `docker exec` in a running container has
|
|
the same capabilities as the container, which may be limited. Set
|
|
`--privileged` to give all capabilities to the process.
|
|
|
|
# USER
|
|
`user` sets the username or UID used and optionally the groupname or GID for the specified command.
|
|
|
|
The followings examples are all valid:
|
|
--user [user | user:group | uid | uid:gid | user:gid | uid:group ]
|
|
|
|
Without this argument the command will be run as root in the container.
