docker-exec - Run a command in a running container
SYNOPSIS
docker exec [-d|--detach[=false]] [--help] [-i|--interactive[=false]] [-t|--tty[=false]] [-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 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
OPTIONS
-d, --detach=true|false Detached mode: run command in the background. The default is false.
--help Print usage statement
-i, --interactive=true|false Keep STDIN open even if not attached. The default is false.
-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.
