# run a command inside a docker container
docker run --rm node ls

# run multiple commands inside a docker container
docker run --rm node bash -c "ls && pwd"

# pipe commands from stdin
echo "ls && pwd" | docker run --rm -i node bash

# pipe commands from script
cat myscript.sh | docker run --rm -i node bash

# do it with docker-compose (drop the "-i" since it will read from STDIN by default)
cat myscript.sh | docker-compose run --rm my-service bash
