This book is about GitOps and Kubernetes, and as such, you’ll need a container registry to publish the containers built throughout the book (see Recipe 2.1).
Also, a Git service is required to implement GitOps methodologies; you’ll learn how to register to public Git services like GitHub or GitLab (see Recipe 2.2).
Finally, it would be best to have a Kubernetes cluster to run the book examples. Although we’ll show you how to install Minikube as a Kubernetes cluster (see Recipe 2.3), and the book is tested with Minikube, any Kubernetes installation should work as well.
Let’s prepare your laptop to execute the recipes provided in this book.
2.1 Registering for a Container Registry
Problem
You want to create an account for a container registry service so you can store generated containers.
Solution
You may need to publish some containers into a public container registry as you work through this book.
Use Docker Hub (docker.io) to publish containers.
If you already have an account with docker.io, you can skip the following steps.
Otherwise, keep reading to learn how to sign up for an account.
Discussion
Visit DockerHub to sign up for an account.
