Kubernetes - Verifying Kubernetes and kubectl Configuration

Step 1: Validate kubeconfig

kubectl is the Kubernetes command-line tool for managing your Kubernetes clusters. If you do not have kubectl, please download it from here: Install Tools

Ensure that it is installed by running the following command:

kubectl version --client

You should see an output displaying the kubectl version. If you do not have kubectl installed, follow these instructions to install it for your operating system.

Step 2: Validate kubeconfig

The kubeconfig file contains the necessary information to authenticate with your Kubernetes cluster. You can verify that the current context is set correctly by running:

kubectl config current-context

The command will return the name of the current context that kubectl is configured to use. Ensure that this context corresponds to the correct Kubernetes cluster where you intend to deploy Scopear. If the context is incorrect, you can switch it using:

kubectl config use-context <your-context-name>

You can list all available contexts with the following:

kubectl config get-contexts

Step 3: Verify Cluster Connectivity

To ensure that kubectl can connect to your cluster, use the following command to list all nodes in the cluster:

kubectl get nodes

This should return a list of nodes, confirming that kubectl is configured correctly and can communicate with your Kubernetes cluster.

Step 4: Check Cluster Permissions

Make sure you have the necessary permissions to deploy resources in the cluster. You can test this by attempting to create a simple resource, such as a namespace:

kubectl create namespace test-namespace

If you have sufficient permissions, the namespace will be created successfully. After verification, you can delete the namespace with:

kubectl delete namespace test-namespace
