docker run <IMAGE> <MULTIPLE COMMANDS>

docker docker-image

To run multiple commands in docker, use /bin/bash -c and semicolon ;

docker run image_name /bin/bash -c "cd /path/to/somewhere; python a.py"

In case we need command2 (python) will be executed if and only if command1 (cd) returned zero (no error) exit status, use && instead of ;

docker run image_name /bin/bash -c "cd /path/to/somewhere && python a.py"

docker docker-image

You can do this a couple of ways:

Use the -w option to change the working directory:
-w, --workdir="" Working directory inside the container
https://docs.docker.com/engine/reference/commandline/run/#set-working-directory--w

Pass the entire argument to /bin/bash:

docker run image /bin/bash -c "cd /path/to/somewhere; python a.py"

docker docker-image

You can also pipe commands inside Docker container, bash -c "<command1> | <command2>" for example:

docker run img /bin/bash -c "ls -1 | wc -l"

But, without invoking the shell in the remote the output will be redirected to the local terminal.
