Learn KUBERNETES with Real Code Examples

Install Kubernetes via kubeadm, minikube, or kind for local clusters

Set up cluster control plane and worker nodes

Configure kubectl CLI for cluster access

Deploy test pods and services

Validate cluster health and networking

Install kubectl CLI

Set up local cluster via minikube/kind or cloud provider

Deploy test workloads

Configure networking, storage, and RBAC

Monitor cluster health and logs

YAML manifests for deployments, services, configmaps, secrets

Helm charts for templated applications

Kustomize overlays for environment-specific customization

RBAC manifests for access control

Storage and volume definitions

kubectl get pods - list pods

kubectl apply -f <manifest> - deploy configuration

kubectl delete -f <manifest> - remove resources

kubectl logs <pod> - inspect logs

kubectl describe <resource> - get detailed info

Dashboard supports multiple languages

YAML manifests are language-agnostic

Logging and monitoring tools support UTF-8

Custom messages can be localized

Documentation available in multiple languages

Cluster accessible via kubectl, API, and dashboard

RBAC controls user and service account access

Namespaces provide logical separation

Ingress exposes selected services externally

CNI plugins manage networking for accessibility

Primarily API and CLI driven

Optional web dashboards like Kubernetes Dashboard

Can integrate with Grafana for visual monitoring

UI reflects cluster resources and status

Custom dashboards possible via API or third-party tools

Pods manage container runtime state

Deployments manage replica and update state

ConfigMaps and Secrets store configuration state

Controllers enforce desired state

Namespaces isolate resources and state per team/project

PersistentVolumes and PersistentVolumeClaims manage storage

ConfigMaps store non-sensitive configuration

Secrets store sensitive data

StatefulSets manage stateful applications

Volume mounts provide persistent storage for pods
