NAME

docker-exec - Run a command in a running container

SYNOPSIS

docker exec [-d|--detach[=false]] [-i|--interactive[=false]] [-t|--tty[=false]] 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. This runs the new process in the background.

-i, --interactive=true|false When set to true, keep STDIN open even if not attached. The default is false.

-t, --tty=true|false When set to true Docker can allocate a pseudo-tty and attach to the standard input of the process. This can be used, for example, to run a throwaway interactive shell. The default value is false.
