Test Docker

The container that obliges good development practices with Docker containers

Support testing Dockerfiles (static code analysis), Images (unit tests), Containers (functional tests) - mostly using Ruby / RSpec plus Dockerlint

Usage

To test this container using this container:

docker-compose up

To build ... have anothet compose file?

How to reuse

Clone the repository

1. Update the Dockerfile to be your Dockerfile
2. Run docker-compose up, it will probably fail
3. Update the image_spec.rb this is your unit testing - don't add tests that need the container to be running
4. Update the container_spec.rb this is your runtime functional testing
5. If your container does work and then stops, ...
6. If your container runs as a daemon, ...
