YACS on Docker!

[Bad-Science]

Resolves #127 - meets specified acceptance criteria.

Docker images:

• rails: The actual YACS application
• nginx: based off of official nginx image with an added config file
• postgres: official postgres image (9.5)
• redis: official redis image

Docker services:

• web: rails container that runs puma
• worker: rails container that runs crono (jobs worker)
• nginx: container running nginx build for serving static files. uses a reverse proxy to forward requests for non-static files to web
• redis: container running redis image
• postgres: container running postgres image

Still to-do:

• Add SSL config to new nginx and puma configs & disable in development

The services are set up with docker-compose (see docker-compose.yml). The app source on the host is set up as a volume and shared between web, worker and nginx services.

The local setup process is defined in https://github.com/YACS-RCOS/yacs/wiki/Local-Setup and is much easier on mac os and windows than it was prior.

SSL config done with #165

However there not appears to be a bug, nginx does not appear to be passing assets requests to rails in development.

edit: fixed with #188

This is done and has been in production for almost a week with no complaints. Merging and releasing.
