NAME

docker-exec - Run a command in an active container

SYNOPSIS

docker exec [-d|--detach[=false]] [-i|--interactive[=false]] [-t|--tty[=false]] CONTAINER COMMAND [ARG...]

DESCRIPTION

Run a process in an existing container. The existing CONTAINER needs to be active.

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.
