Deploy microservices using kubectl manifests that define Deployments, Services, and resource requests. Apply templates to your cluster, configure liveness and readiness probes for health checks, and verify Pod status with kubectl get pods and kubectl logs to confirm successful rollout.

Diagnose Pod failures by running kubectl describe pod, kubectl logs, and kubectl get events to review recent cluster activity. Check resource requests, limits, probe configurations, and service connectivity. These troubleshooting steps isolate whether the failure stems from resource constraints, misconfiguration, or application errors.

Helm streamlines Kubernetes deployments by templating manifests and managing releases. Use helm install to deploy charts, helm upgrade to apply configuration changes, and helm rollback to revert to previous versions, automating the full lifecycle from development through production.

Yes. kubectl provides commands to inspect Pod resources, node status, and events. Collect logs with kubectl logs, monitor resource allocation against requests and limits, and verify service exposure and network policies are correctly configured for your workload scaling requirements.

Liveness probes restart Pods that become unresponsive; readiness probes remove Pods from load balancers until they are healthy. Both are critical patterns in Kubernetes manifests to ensure only healthy Pods receive traffic and failed instances are automatically recovered.

Scale microservices by defining resource requests, limits, and replica counts in Deployment manifests. Kubernetes distributes Pods across nodes based on these constraints. Use kubectl scale or update the manifest replicas field, then verify Pod distribution with kubectl get pods across nodes.
