Docker-multirun NPM

docker-multirun

Run a docker container via docker-run multiple times. Works like docker-compose by keeping the container and reusing the volumes.

There are many cases where you run a task repeatedly, but do not want to throw away the whole container. One frequent task is running tests in a docker container. You want to keep the installed node_modules files and then run the tests multiple times.

docker-multirun is like docker-run, but reuses the volumes of the already-existing container. This way, generated files from the previous run are kept. This behavior is also known from docker-compose.
