Minikube Cluster Verification

Minikube Cluster Verification is the process of confirming that the local Kubernetes environment provided by Minikube is running correctly and that the command-line tool kubectl is properly configured to interact with it^[400-devops-06-kubernetes-minikube-01-install.md].

Verification Commands

To ensure the cluster is operational, users typically execute a sequence of status-check commands immediately after starting the cluster^[400-devops-06-kubernetes-minikube-01-install.md].

1. Minikube Status

The primary method for checking the health of the Minikube instance is the minikube status command^[400-devops-06-kubernetes-minikube-01-install.md]. This command verifies the state of the cluster's core components.

A successful verification output should indicate the following statuses: * host: Running^[400-devops-06-kubernetes-minikube-01-install.md] * kubelet: Running^[400-devops-06-kubernetes-minikube-01-install.md] * apiserver: Running^[400-devops-06-kubernetes-minikube-01-install.md] * kubeconfig: Configured^[400-devops-06-kubernetes-minikube-01-install.md]

2. Cluster Information

Users can verify the network endpoints and service discovery using kubectl cluster-info^[400-devops-06-kubernetes-minikube-01-install.md]. This command confirms that the Kubernetes control plane is running and displays the URL where it is accessible^[400-devops-06-kubernetes-minikube-01-install.md]. It also lists the status of critical cluster services, such as CoreDNS^[400-devops-06-kubernetes-minikube-01-install.md].

3. Node Status

The kubectl get nodes command is used to inspect the compute resources within the cluster^[400-devops-06-kubernetes-minikube-01-install.md].

In a standard single-node Minikube setup, the output should show: * NAME: minikube^[400-devops-06-kubernetes-minikube-01-install.md] * STATUS: Ready^[400-devops-06-kubernetes-minikube-01-install.md] * ROLES: control-plane,master^[400-devops-06-kubernetes-minikube-01-install.md]

Verification Context

This verification step usually follows the initialization of the cluster using a start command that defines specific configurations, such as the container runtime (e.g., Docker), CPU count, memory allocation, and network plugins like Flannel^[400-devops-06-kubernetes-minikube-01-install.md].
