도커 Container 내부에서 명령어 실행

Usage:

 docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

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. If the underlying image has a custom directory specified with the WORKDIR directive in its Dockerfile, this will be used instead.

 

COMMAND should be an executable, a chained or a quoted command will not work.

Example: docker exec -ti my_container "echo a && echo b" will not work, but docker exec -ti my_container sh -c "echo a && echo b" will.
