One popular option for installing Kubernetes is through minikube, which creates a local Kubernetes cluster for different environments. Tests scripts and examples for the clickhouse-operator
are based on using minikube
to set up the Kubernetes environment.
The following guide demonstrates how to install minikube that support the clickhouse-operator
for the following operating systems:
