As we can see the cluster name is minikube.

4. kubectl config use-context <context-name>

To switch to a different context as specified in the config file.

5. kubectl config set-cluster <cluster-name> –server=<server> –certificate-authority=<path-to-ca-cert>

Here e2e is our new cluster.

6. kubectl config set-credentials <user-name> –client-certificate=<path-to-client-cert> –client-key=<path-to-client-key>

The container is a package that comprises code and libraries that are to be executed. Now to automate the deployment of Containers we need Kubernetes or K8s. Kubernetes or K8s is an open source that is used for the deployment of containers. It is a container orchestration platform that is used to automate the deployment of containers. They help to manage, schedule, and scale the applications. Kubernetes should be confused with cloud services. They are basically integrated with cloud services in order to generate comprehensive solutions.

If we go through the structure, Kubernetes basically makes use of clusters. Inside clusters there exists nodes or physical machines. Inside those physical machines are pods. Inside pods, there exist containers.
