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:
Always start with
kubectl– it's your gateway to the cluster.Use Minikube or Kind to practice Kubernetes locally.
Master the YAML syntax – it's everywhere in Kubernetes.
Learn the difference between Deployments, StatefulSets, and DaemonSets.
Namespace everything to avoid conflicts in multi-team setups.
Use ConfigMaps and Secrets to separate configuration from code.
Set up resource requests/limits to prevent pod starvation.
Understand Kubernetes Services – ClusterIP, NodePort, and LoadBalancer.
Learn about Ingress for HTTP routing into your cluster.
Use liveness and readiness probes to manage container health.
Avoid storing credentials in plain YAML files – use Secrets instead.
Familiarize yourself with Helm for managing application releases.
Explore Kustomize for environment-specific configuration.
Use metrics-server for resource monitoring.
Set up Role-Based Access Control (RBAC) for secure operations.
Start with a simple CNI plugin like Flannel for networking.
Use Kubernetes Dashboard cautiously – it's great for beginners but can expose your cluster.
Experiment with auto-scaling – both HPA (pods) and Cluster Autoscaler (nodes).
Regularly clean up unused resources like pods, services, and images.
Document everything – Kubernetes has a steep learning curve.
Save this one for your reference.
