Kubernetes

Apply manifests to your cluster using kubectl apply -f and verify rollout status with kubectl rollout status. This ensures your deployments, pods, and resources are created correctly and reach the desired state across your cluster.

RBAC (role-based access control) restricts user and service account permissions in Kubernetes through Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings. Define these resources in YAML manifests to enforce least-privilege access and cluster hardening.

Use kubectl logs, kubectl describe, and kubectl exec to inspect pod behavior and diagnose failures. Verify readiness and liveness probes, resource requests and limits, and check events across namespaces to isolate cluster and deployment problems.

Enforce non-root execution, configure secure kubeconfig handling, apply network policies, set explicit resource requests and limits, use consistent labeling, and implement RBAC patterns. These practices harden clusters across cloud and on-prem environments.

Use kubectl namespace commands and manifest labels to segment resources and control access. Organize deployments, services, and configurations by namespace to isolate workloads and apply RBAC policies at namespace and cluster scope.

Yes, network policies define ingress and egress rules for pod-to-pod communication. Declare them in YAML manifests and apply with kubectl to restrict traffic flow and enforce zero-trust networking within your cluster.
