Frequently Asked Questions
Answers to common questions from community members
How do I get started with Kubernetes?
Answer: Start with the official Kubernetes documentation at kubernetes.io/docs. Set up a local environment using Minikube, Kind, or Docker Desktop. Follow the "Getting Started" guide on this site for installation steps. Practice basic commands like kubectl create, get, describe, and logs.
What's the difference between kubectl and helm?
Answer: kubectl is the Kubernetes command-line tool for managing clusters and resources directly. Helm is a package manager for Kubernetes that uses charts (bundles of YAML templates) to simplify deployments. Use kubectl for direct management; use Helm for packaging and distribution.
How do I debug a failing Pod?
Answer: Use these commands:
kubectl describe pod <name> (check events)
kubectl logs <name> (check application logs)
kubectl exec -it <name> -- /bin/sh (shell into container)
Check the "Troubleshooting & Debugging" page for detailed guidance.
What are the security best practices?
Answer: Key practices: Use RBAC to restrict permissions, enforce network policies, scan container images for vulnerabilities, use secrets management tools, run containers as non-root, enable Pod Security Policies, implement audit logging, and keep Kubernetes updated. See the "Cluster Security & RBAC" page for detailed guidance.
How do I scale my application?
Answer: Use Horizontal Pod Autoscaling (HPA) to automatically scale based on CPU/memory or custom metrics. Use Vertical Pod Autoscaling (VPA) for right-sizing resource requests. Use Cluster Autoscaling to add/remove nodes. See the "Cost Optimization" page for implementation examples.
Should I use a service mesh?
Answer: Service meshes (Istio, Linkerd) add advanced networking, security, and observability. They're valuable for complex microservices architectures, but add operational overhead. Start without one; adopt if you need traffic splitting, mutual TLS, or distributed tracing. See "Advanced Topics" for comparison.
What's the proper way to update a Deployment?
Answer: Use rolling updates (default) for zero-downtime deployments, blue-green deployments for atomic switches, or canary deployments for gradual rollout. Update the Deployment spec; the rolling update controller handles the rest. Use readiness/liveness probes for health checks during updates.
How do I handle stateful applications?
Answer: Use StatefulSets for ordered, stable pod identities and persistent storage. Use persistent volumes (PV) and persistent volume claims (PVC) for data durability. Consider managed databases (AWS RDS, Cloud SQL) for production workloads. See "Real-World Examples" for database deployment patterns.
Contributing to Kubernetes
How to contribute to the open-source project
Ways to Contribute
- Code: Fix bugs, implement features, improve performance. Start with issues labeled "good first issue" or "help wanted".
- Documentation: Write guides, fix typos, improve clarity. Documentation is crucial for all skill levels.
- Testing: Write tests, report bugs, test new features on different environments.
- Community: Answer questions in Slack/forums, lead local meetups, speak at conferences.
- SIGs: Join Special Interest Groups (SIGs) focusing on specific areas: API machinery, cluster management, network, security, storage, etc.
Steps to Contribute Code
- Setup: Fork the kubernetes/kubernetes repository on GitHub
- Branch: Create a feature branch from main:
git checkout -b my-feature - Code: Make changes following the contribution guidelines and code style
- Tests: Add/update tests to ensure your changes work correctly
- Commit: Write clear, descriptive commit messages
- Push: Push to your fork:
git push origin my-feature - PR: Open a Pull Request with detailed description of changes
- Review: Respond to reviewer feedback and make requested changes
- Merge: Your PR is merged when approved
