NAME
       docker-exec - Run a command in a running container



SYNOPSIS
       docker  exec [-d|--detach] [--detach-keys[=[]]] [--help] [-i|--interac-
       tive] [--privileged] [-t|--tty]  [-u|--user[=USER]]  CONTAINER  COMMAND
       [ARG...]



DESCRIPTION
       Run a process in a running container.


       The  command  started  using  docker  exec will only run while the con-
       tainer'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



OPTIONS
       -d, --detach=true|false
          Detached mode: run command in the background. The default is false.


       --detach-keys=""
         Override the key sequence for detaching a container. Format is a sin-
       gle character [a-Z] or ctrl-<value> where <value> is one of: a-z, @, ^,
       [, , or _.


       --help
         Print usage statement


       -i, --interactive=true|false
          Keep STDIN open even if not attached. The default is false.


       --privileged=true|false
          Give    the     process     extended     <http://man7.org/linux/man-
       pages/man7/capabilities.7.html>   when  running  in  a  container.  The
       default is false.


       Without this flag, the process run by docker exec  in  a  running  con-
       tainer  has  the  same capabilities as the container, which may be lim-
       ited. Set --privileged to give all capabilities to the process.


       -t, --tty=true|false
          Allocate a pseudo-TTY. The default is false.


       -u, --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.


       The  -t  option is incompatible with a redirection of the docker client
       standard input.
