Exec Solutions
Solution 1 - Exec
cd is a built-in shell command, you can't set it as the command to run. You have to use:
docker exec -i compassionate_mclean bash -c "cd /root/python && python myscript.py"
If you want to see the output make sure to add the -i flag as shown above. In this case however, you can simply run python as your entrypoint:
docker exec -i compassionate_mclean python /root/python/myscript.py
Solution 2 - Exec
You can't do that, you can do either docker exec -it my_container /bin/bash and then issue several commands with this interactive sessions, or docker exec -d my_container touch myfile if you just want to create a file, see the examples at https://docs.docker.com/reference/commandline/cli/#examples_3
Solution 3 - Exec
If u execute docker container exec --help , it will show the options and method to execute the command Usage: docker container exec [OPTIONS] CONTAINER COMMAND [ARG...]
U have to use docker container exec -it [container_name] bash
Once u are in bash then u can execute any command you wish. Doing CD wont work.
