The docker exec command runs a new command in a running container. The command started using docker exec only runs while the container's primary process ( PID 1 ) is running, and it is not restarted if the container is restarted. COMMAND will run in the default directory of the container.
For containers that are stopped, you can also start the container using the Docker start command and then run the Docker exec command.
Docker Run vs Docker Exec! This is a fairly common question – but has a simple answer! In short, docker run is the command you use to create a new container from an image, whilst docker exec lets you run commands on an already running container!
A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
You need to allocate a pseudo-TTY with the -t option along with interactive or -i option. Try this:
$ docker exec -ti <container-id> sh -c "ls -l"
