Development Dockerfile

[doug-fitzmaurice-rowden]

Add a basic docker setup for development

This doesn't keep a copy of the code in the container - it's mounted in at runtime to make testing and iteration quicker. takyctl setup is run automatically on first run to create certificates and config, then the /etc/taky directory is mounted out to the local ./docker directory so the config can be edited.

Usage:

docker-compose build
docker-compose up
