Prerequisites

• kubectl installed and configured.

• Access to the Kubernetes cluster via kubeconfig.

• Permissions to interact with the required resources.

• Optional: Helm installed for managing applications.

Ways to Access Kubernetes Resources

There are multiple methods to access Kubernetes resources, each suited for different use cases:

1. Using kubectl

kubectl is the primary CLI tool for interacting with Kubernetes resources.

a) View Resources

• List all pods:

  1kubectl get pods -n <namespace>

• Describe a specific pod:

  1kubectl describe pod <pod-name> -n <namespace>

• Get logs from a pod:

  1kubectl logs <pod-name> -n <namespace>

• Execute commands inside a running pod:

  1kubectl exec -it <pod-name> -n <namespace> -- /bin/sh

Common Kubernetes Resources

• Pods: The smallest deployable units.

• Services: Expose applications running on pods.

• Deployments: Manage replica sets and rollouts.

• ConfigMaps & Secrets: Store configuration and sensitive information.

• PersistentVolumes & PersistentVolumeClaims: Manage storage.

• Namespaces: Isolate resources within a cluster.

• Ingress: Route external traffic into the cluster.

Troubleshooting

• kubectl command fails: Ensure kubectl is authenticated and has access to the cluster

• Permission denied errors: Verify your role-based access control (RBAC) settings
