Action Cable debuted at RailsConf 2015 and is now part of Rails 5. Built on top of WebSockets it provides real time communication with your backend server.
In this step we setup a custom domain name to point at our Elastic Beanstalk environment and configure it to use SSL.
In the previous step we deployed our Rails application from the command line to Elastic Beanstalk. In this step we setup CircleCI to deploy our application directly out to Elastic Beanstalk when code is pushed to GitHub.
In this fourth step we create a new Rails application, scaffold a model and deploy the application out to Elastic Beanstalk from the command line. We connect this application up to our RDS instance and show that it connects successfully with the dev database.
In this third step we create an RDS instance running Postgres in our VPC using our private subnets. We connect to the database using our Bastion server and create dev and production databases.
