Kubernetes Recipes

5 steps|10 min|health, monitoring, cluster

Run comprehensive health checks on your Kubernetes cluster to verify node status, component health, and system pod readiness.

$ kubectl get nodes -o wide

4 steps|5 min|logs, debugging, streaming

Log Aggregation and Streaming

Beginner

Stream and aggregate logs from pods, deployments, and multiple containers using kubectl and label selectors.

$ kubectl logs -f <pod-name>

Namespace Management

5 steps|10 min|namespaces, multi-tenant, quotas

Create, organize, and manage Kubernetes namespaces with resource quotas and limit ranges for multi-tenant clusters.

$ kubectl get namespaces -o custom-columns='NAME:.metadata.name,STATUS:.status.phase,AGE:.metadata.creationTimestamp'

Network Policy Debugging

5 steps|15 min|networking, security, network-policy

Debug and verify Kubernetes network policies to ensure traffic is correctly allowed or blocked between pods and services.

$ kubectl get networkpolicies -n <namespace> -o wide

Pod Debug with Ephemeral Containers

5 steps|10 min|debug, pods, ephemeral

Debug running pods using ephemeral debug containers, especially useful for distroless images that lack debugging tools.

$ kubectl debug -it <pod-name> --image=busybox --target=<container-name>

4 steps|5 min|pods, debugging, status

Pod Status Analyzer

Beginner

Quickly diagnose common pod failure states including CrashLoopBackOff, ImagePullBackOff, Pending, and OOMKilled.

$ kubectl get pods -o custom-columns='NAME:.metadata.name,STATUS:.status.phase,RESTARTS:.status.containerStatuses[0].restartCount,REASON:.status.containerStatuses[0].state.waiting.reason'

RBAC Auditing Workflow

5 steps|15 min|rbac, security, audit

Audit Role-Based Access Control (RBAC) permissions to identify overly permissive roles and verify least-privilege access.

$ kubectl get clusterroles -o custom-columns='NAME:.metadata.name,RULES:.rules[*].verbs'

Resource Optimization Audit

4 steps|10 min|resources, optimization, cost

Audit resource requests and limits across your cluster to find over-provisioned or under-provisioned workloads.

$ kubectl top pods --all-namespaces --sort-by=memory

Rollout Management

5 steps|15 min|deployments, rollout, rollback

Manage deployment rollouts including monitoring progress, pausing, resuming, and rolling back to previous versions.

$ kubectl rollout status deployment/<deployment-name>

Secret Rotation Automation

5 steps|15 min|secrets, security, rotation

Manage and rotate Kubernetes secrets safely, including creating, updating, and verifying secret propagation to pods.

$ kubectl get secrets -n <namespace> -o custom-columns='NAME:.metadata.name,TYPE:.type,AGE:.metadata.creationTimestamp'
