Docker suite for development

NOTE: This exists only for local development. If you're interested in using Docker for a production setup, visit the docs instead.

Objective

The purpose of this docker suite for local development is to isolate all the dev dependencies in a docker environment. The containers have a host volume mounted inside for the entire app directory. This helps us to not do a full docker build for every single local change, only restarting the docker environment is enough.

Setting up a dev suite

To spin up a local suite of

PostgreSQL
Mailhog
Node.js frontend app
Golang backend app

Setup DB

make init-dev-docker

Start frontend and backend apps

make dev-docker

Visit http://localhost:8080 on your browser.

Tear down

This will tear down all the data, including DB.

make rm-dev-docker

See local changes in action

Backend: Anytime you do a change to the Go app, it needs to be compiled. Just run make dev-docker again and that should automatically handle it for you.
Frontend: Anytime you change the frontend code, you don't need to do anything. Since yarn is watching for all the changes and we have mounted the code inside the docker container, yarn server automatically restarts.
