Introduction

Main purpose of this project is to learn how to create a docker container.

This projects runs smashtest via a docker container.

Additional steps for creating a docker container will be added to this project readme.

Prerequisite

Ensure nodejs is installed. Nodejs installation instructions

How-to Run

1. docker-compose down - to ensure nothing is left over.
2. docker-compose build - to build the container
3. docker-compose up -d - Run's a container with node and smashtest code.
4. docker-compose run --rm testserver npx smashtest - Executes the npx smashtest command against the docker-compose'd container.

How-to Clean-up

NOTE This will delete all containers and images. If you want a more targetted clean up specify each container and image.

1. docker-compose down
2. docker container prune -f
3. docker image prune -f --all

Lessons learnt:

• yml files are very specific with whitespace for name:value and everything else.
• best not to use a latest specified image as it seems docker-compose will always check and download it.
• This maybe obvious but dockerfile and docker-compose have differences understanding what's runnig from which section is important. Eg. When to use them to run/volume map etc matters.
