In this book I'll show you all of the things you need to successfully deploy a Rails API application using Kubernetes. This technology was created by Google and quickly became one of the most used containerization solution with big customers like Ebay and The New York Times.

  • Dockerize this application by using Docker and Docker Compose (AVAILABLE)
  • Write templates to run this application with Kubernetes (AVAILABLE)
  • Write templates to run Jobs your application may require (migrations) (AVAILABLE)
  • Test these template on a local cluster with Minikube (AVAILABLE)
  • Create a Kubernetes cluster in AWS (AVAILABLE)
  • Run your templates in the AWS cluster (AVAILABLE)
  • Create AWS Volumes for persisting your container's data (AVAILABLE)
  • Inspecting and troubleshooting problems in the cluster
  • Run updates to your code with the new concept of "deployments" (AVAILABLE)
  • Automatize the the whole deployment procces with Jenkins (AVAILABLE)
