Setup guide

To start your Phoenix app:

• Install dependencies with mix deps.get
• Add the necessary variables to your environment
• Create and migrate your database with mix ecto.create && mix ecto.migrate
• Start Phoenix endpoint with mix server

Deploy

We're using edeliver. We're using cold deploys, not upgrades. The deployment process is done using the following commands:

• mix edeliver build release
• mix edeliver deploy release production
• mix edeliver restart production
• mix edeliver migrate production

Note that trying to stop the api from edeliver won't be too successfull as systemd will notice its absence and restart it immediatly.

We try to preserve our deps' built files. If you need to clean those for some reason, run GIT_CLEAN_PATHS=. mix edeliver build release.
