- How to get your Rails app ready for production. Once ready, you will provision machines, create a cluster, deploy the app, and scale its resources to meet its changing needs using Docker's own tools.
- You will then work to get your Dockerized setup to cooperate with JavaScript, utilising both the standard asset pipeline and webpacker, Rails' newest approach for integrating modern JavaScript front ends.
- Learn the Docker fundamentals you need to know to get you off the ground
- Get your hands dirty making and running the real Rails app
- Learn how Compose allows adding multiple services
- Learn to integrate a frontend option with your Rails app
- Use Docker to deploy the Rails app to Cloud
