# 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.
