docker build -t infra-101-best-ever .

Rebuilding the docker image to reflect code changes is time consuming. You can bypass this by mounting the local file system to the docker container using the -v flag:

docker run --rm -v $(pwd):/app infra-101-best-ever npm install

Running tests:

docker run --rm -v $(pwd):/app infra-101-best-ever npm test

A makefile can simplify invoking the above commands.

• make build: Build docker image for app
• make shell: Open interactive shell for docker container
• make test: Run tests in docker container
• make start: Start app in docker container
