Subject: [PATCH] Set up GitHub Actions (#72)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add GitHub Actions config

* Add extra dependencies and use environment variable for DB config

Moved the env vars up to outside of the postgres service so this might not work

* Pass environment variables for Postgres credentials to Postgres container

* Pass service ports to application

Have a suspicion that Redis one won't work as justask.yml is probably not using ERB

* Add database.yml.postgres with port

* Cache gems; pass Redis URL as env var

* Add host to DB config

* Pass DB credentials for db:setup

* Use 127.0.0.1 instead of localhost to force TCP; Use bundler config without instead of --without

* I can't read 🗑

* 🤔

* 💻🔨 I have no idea what I'm doing…

* Testing env defined outside steps

* Move templated vars down

* Add build badge
