minikube

These days I’m learning how to develop Kubernetes operators in Go. Although I had developed programs in Go before, I never did that to extend Kubernetes. For this, a running cluster is required. So, I needed a Kubernetes cluster. The best option for this was to create a local one. Using a local Kubernetes cluster as development environment saves costs and reduces workload and time. Fortunately I have experience managing single node clusters with different distros.

Minikube is a tool to run Kubernetes locally as a single-node cluster, which is very useful for learning and developing. A regular Kubernetes installation needs at least three hosts. The first one will be the Kubernetes Master, the cluster manager. The rest will be Kubernetes Nodes, which are responsible for running the workloads. Installing kubectl There is a tool called kubectl for managing Kubernetes clusters. We will install it before, and Minikube installation process will configure it correctly.
