Starting up with Kubernetes

If you are starting up with Kubernetes or working with it then it is for you.
Someone is digging into Kubernetes concepts, tools, and best practices – so you don’t have to.

Here are 20 must-know updates and tips to get started with Kubernetes:

  1. Always start with kubectl – it's your gateway to the cluster.

  2. Use Minikube or Kind to practice Kubernetes locally.

  3. Master the YAML syntax – it's everywhere in Kubernetes.

  4. Learn the difference between Deployments, StatefulSets, and DaemonSets.

  5. Namespace everything to avoid conflicts in multi-team setups.

  6. Use ConfigMaps and Secrets to separate configuration from code.

  7. Set up resource requests/limits to prevent pod starvation.

  8. Understand Kubernetes Services – ClusterIP, NodePort, and LoadBalancer.

  9. Learn about Ingress for HTTP routing into your cluster.

  10. Use liveness and readiness probes to manage container health.

  11. Avoid storing credentials in plain YAML files – use Secrets instead.

  12. Familiarize yourself with Helm for managing application releases.

  13. Explore Kustomize for environment-specific configuration.

  14. Use metrics-server for resource monitoring.

  15. Set up Role-Based Access Control (RBAC) for secure operations.

  16. Start with a simple CNI plugin like Flannel for networking.

  17. Use Kubernetes Dashboard cautiously – it's great for beginners but can expose your cluster.

  18. Experiment with auto-scaling – both HPA (pods) and Cluster Autoscaler (nodes).

  19. Regularly clean up unused resources like pods, services, and images.

  20. Document everything – Kubernetes has a steep learning curve.

Save this one for your reference.
