kubernetes-manifests

Kubernetes manifests are YAML files that define container deployments. Write manifests specifying Pods, Deployments, Services, and ConfigMaps with resource requests, limits, labels, and selectors to orchestrate your containers across a cluster.

Validate manifests using kubectl dry-run to simulate deployment without applying changes, and kubeconform to check YAML against Kubernetes API schemas. Both catch syntax errors and invalid resource specifications early.

Yes. ConfigMaps store non-sensitive configuration data and Secrets store sensitive data like credentials. Both are defined as manifest resources and referenced by Pods and Deployments for configuration injection.

Specify resource requests and limits in manifest containers to control CPU and memory allocation. Add liveness and readiness probes to monitor container health and enable automatic restarts or traffic rerouting.

Labels are key-value pairs attached to resources for organization and querying. Selectors in Services and Deployments use labels to match and group Pods, enabling dynamic service discovery and pod management.

No. After validation, deploy manifests using kubectl apply to push configurations to your Kubernetes cluster. This creates or updates the defined resources—Deployments, Services, ConfigMaps, and Secrets—in one operation.
