Architecture

We have one Dockerfile which consists of three stages:

1. A Elixir app which compiles, fetches dependencies, ...
2. A node.js app which compiles the assets. It uses libraries from the Elixir app.
3. A production stage which copies the results from (1) and (2) and runs them.

In development we split the Dockerfile up into two separate containers (using the target directive) to continously re-compile the app and its assets.

Both containers share a volume with docker-sync to perfomantly access changed files as well as for the Elixir app to deliver the compiled assets.

Developers can mount more Containers into the stack with a custom docker-compose.user.yml file. It can look like this:

  version: "3.4"

  services:
      adminer:
          image: adminer
          ports:
            - 8080:8080
          environment:
            ADMINER_DEFAULT_SERVER: db
            ADMINER_DESIGN: pepa-linha

Setup

Prerequisites

Install:

• Docker
• Docker-Compose

Development

• Run bin/dev, it will run the three containers specified below. You can access the website by visiting http://localhost:4000.
• Run bin/seed to seed the database.

After the initial start things might be wonky. Just restart the app and you should be fine. There are two cases where you need to interact with Docker directly:

• In some cases the containers won't stop after ctrl + c and keep running in the background (docker ps). If so you need to run docker-compose down manually. The same goes for the tests.

Testing

Unittesting

If you like you can run bin/test up, which will start a separate stack which continuously runs tests agains a test database.

Update

Elixir

• Check for outdated deps with bin/compose run app mix hex.outdated and maybe change version constraints in mix.ex.
• Run bin/compose run app mix deps.update --all
• Check app for errors before commiting

Yarn

• Check for outdated deps with bin/compose run assets yarn outdated and maybe change version constraints in assets/package.json.
• Run bin/compose run assets yarn upgrade
• Check app for errors before commiting

Hosting and Deployment

• Production URL: absolventenfeier.de
• GitHub builds containers for each commit. Master commits will be pushed to Docker Packages.
• Server listens with watchtower for changes and restarts app container.
