Dockerize Rails 7 with ActionCable, Webpacker, Stimulus, Elasticsearch, Sidekiq

Docker-Rails

Simple Rails 7.0 application to demonstrate using Docker for production deployment. The application is a very simple kind of CMS (content management system) allowing to manage posts. Beside the boring CRUD functionality it has some non-default features.

This project aims to build a lean Docker image for use in production. Therefore it's based on the official Alpine Ruby image, uses multi-stage building and some optimizations that I described in my blog. This results in an image size of ~80MB.

Features

• Auto refresh via ActionCable: If a displayed post gets changed by another user/instance, it refreshes automatically using the publish/subscribe pattern
• Full text search via OpenSearch and the Searchkick gem to find post content (with suggestions)
• Autocompletion with autocompleter
• Editing HTML content with the WYSIWYG JavaScript editor Trix
• Uploading images directly to S3 with the Shrine gem and jQuery-File-Upload
• Background jobs with ActiveJob and the Sidekiq gem (to handle full text indexing, image processing and ActionCable broadcasting)
• Cron scheduling with Sidekiq-Cron to handle daily data updates from Wikipedia
• Permalinks using the FriendlyId gem
• Infinitive scrolling (using the Kaminari gem and some JavaScript)
• User authentication with the Clearance gem
• Sending HTML e-mails with Premailer and the Really Simple Responsive HTML Email Template
• Admin dashboards with Blazer gem
• JavaScript with Stimulus
• Bundle JavaScript libraries with Yarn

Why?

This project demonstrates my way of building Rails applications. The techniques used to build the app should not be considered as "best practice", maybe there are better ways to build. Any feedback would be appreciated.

Multi container architecture

There is an example docker-compose.production.yml. The whole stack is divided into multiple different containers:

• app: Main part. It contains the Rails code to handle web requests (by using the Puma gem). See the Dockerfile for details. The image is based on the Alpine variant of the official Ruby image and uses multi-stage building.
• worker: Background processing. It contains the same Rails code, but only runs Sidekiq
• db: PostgreSQL database
• opensearch: Full text search engine
• redis: In-memory key/value store (used by Sidekiq, ActionCable and for caching)
• backup: Regularly backups the database as a dump via CRON to an Amazon S3 bucket

Check it out!

To start up the application in your local Docker environment:

git clone https://github.com/ledermann/docker-rails.git
cd docker-rails
docker-compose build
docker-compose up

Wait some minutes while the database will be prepared by fetching articles from Wikipedia. Then, navigate your browser to http://[DOCKER_HOST]:[DOCKER_PORT].

Sign in to the admin account:

• Username: [email protected]
• Password: secret

Enjoy!

Tests / CI

On every push, the test suite (including RuboCop checks) is performed via GitHub Actions. If successful, a production image is built and pushed to GitHub Container Registry.

Production deployment

The Docker image build includes precompiled assets only (no node_modules and no sources). The spec folder is removed and the Alpine packages for Node and Yarn are not installed.

The stack is ready to host with traefik or nginx proxy and letsencrypt-nginx-proxy-companion.

Demo

A demo installation is set up on https://docker-rails.ledermann.dev.

docker-rails's Issues

Logo Design/Docker-Rails

Hey, I examined that your project has no logo design yet. If you interested I can design a logo for Docker-Rails. We can improve it together if you have an idea or want to add/remove something on design. I'm waiting your feedbacks, have a nice day! (it is not advertisement or something, I want to contribute on your project)

Is there a missing "copy . /app" in Dockerfile?

I'm not sure if I'm doing something completely wrong. I've closed this repo and tried to run it, but I get the error below.
Looking at the Dockerfile, I don't see a copy command to get the rails app into docker. I've added this to my own app, which seems to be working. But in this example app (which I really appreciate btw it's incredibly fast to build) doesn't seem to work.

what/where is URL to access app locally?

git clone https://github.com/ledermann/docker-rails.git
cd docker-rails
docker-compose build
docker-compose up

Um, out of the box, what is the URL... e.g., what/where is DOCKER_HOST?

On Mac, neither 127.0.0.1:3000 nor localhost:3000 do not work.

When running Docker-compose up, it does show Listening on http://0.0.0.0:3000 but I do not see what DOCKER_HOST is expected to access locally via browser.

An in-range update of react is breaking the build 🚨

There have been updates to the react monorepo:

• • The dependency react was updated from 16.5.2 to 16.6.0.

• The dependency react-dom was updated from 16.5.2 to 16.6.0.

🚨 View failing branch.

This version is covered by your current version range and after updating it in your project the build failed.

This monorepo update includes releases of one or more dependencies which all belong to the react group definition.

react is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.

How run Rspec (and scaffolding)

This cool a multi-stage Dockerize Rails app you have created. But after doing a quick smoke-test docker build . then docker-compose up browsing the app, then ^C to quit, I am now trying to get past some of the magic obscuring the most basic workflows.

It's probably my lack of experience with multi-stage builds, but anything rspec-related does not seem accessible the usual way:

How does one invoke rspec locally, and, invoke scaffolding to create rspec tests instead of /app/test?

docker-compose run --rm app rspec

gives:

Error response from daemon: OCI runtime create failed: container_linux.go:367: starting container process caused: exec: "rspec": executable file not found in $PATH: unknown
ERROR: 1

or

docker-compose run --rm app rails g scaffold Foo title:string body:text status:string

fails when tries to create spec in test folder stead of rspec folder:

      invoke  active_record
      create    db/migrate/20210518034404_create_foos.rb
      create    app/models/foo.rb
      invoke    test_unit
/usr/local/lib/ruby/3.0.0/fileutils.rb:253:in `mkdir': Permission denied @ dir_s_mkdir - /app/test (Errno::EACCES)

Direct upload to S3

Hot reloading of JavaScript

Does this project support hot reloading of assets via the webpack dev server? If yes, does it come out of the box?

Running in Development

Not sure it's an issue. I don't have Rails installed locally and I'm facing this error when I change Gemfile and run docker-compose run app bundle install

There was an error while trying to write to /usr/local/bundle/config. It is likely that you need to grant write permissions for that path.

What's the proper way to deal with this and use in dev mode?

Yarn is missing in the app-container in develop branch?

I followed the Readme, with the following commands.

git clone https://github.com/ledermann/docker-rails.git
cd docker-rails
docker-compose build
docker-compose up

However when accessing http://[DOCKER_HOST]:[DOCKER_PORT], this error is printed.

app_1            | F, [2020-05-06T08:44:05.781549 #56] FATAL -- : [ba24857e-394d-4191-b134-27e8dce2f648]

app_1            | 1. You want to set webpacker.yml value of compile to true for your environment
app_1            |    unless you are using the `webpack -w` or the webpack-dev-server.
app_1            | 2. webpack has not yet re-run to reflect updates.

app_1            | Your manifest contains:
app_1            | {

So found in the master branch that I need to run

 docker-compose run app yarn install

However Yarn does not exists in the app-container.

Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"yarn\": executable file not found in $PATH": unknown

So what I did to solve this was

docker-compose exec -u root app run apk add yarn
docker-compose exec app sh
yarn install

But still no luck, after restarting the server.

Switching to the master branch, and running the setup, works fine.

Feature request: Add support for running the project in a development container in VS Code

vscode has the ability to add a configuration that will allow you to run your rails environment in a development container: https://code.visualstudio.com/docs/remote/create-dev-container
It would be great to add support for that.

Some low-effort gems you could add

This is a great idea! It's hard to find simple, production-ready implementations of rails tools in the wild. This is quite refreshing.

Have you considered adding these gems: 'searchjoy', 'pghero', 'friendly_id', 'bootsnap', or 'oj'?

Development

In docker, the idea is to mantain more or less the same dockerfiles (or docker-compose) between development and production enviroments. In the case of development, what's your recommendation?

For example, a proper .dev with RAILS_ENV=production, eliminate NGINX (Puma or Unicorn is enough). What about logging?

Thanks for sharing your work!
