Kubernetes Tutorials
Kubernetes provides a comprehensive curriculum for container orchestration and cloud - native applications. Our tutorials cover Kubernetes concepts, deployment strategies, and scaling techniques, suitable for both beginners and experienced DevOps professionals. With free labs and real - world examples, you'll gain practical experience in managing containerized applications. Our K8s playground allows you to experiment with Kubernetes configurations in a simulated environment.

Troubleshoot Kubernetes Pods and Containers
Diagnose image, startup, and multi-container failures with Pod conditions, events, logs, previous logs, and kubectl exec.
Kubernetes
Secure Kubernetes Access with RBAC
Apply least-privilege Kubernetes RBAC with ServiceAccounts, Roles, RoleBindings, impersonation, and kubectl auth can-i.
Kubernetes
Improve Kubernetes Reliability with Health Probes
Use startup, readiness, and liveness probes plus graceful termination to make Kubernetes application health observable and actionable.
Kubernetes
Configure Kubernetes Apps with ConfigMaps and Secrets
Configure Kubernetes applications with ConfigMaps and Secrets through environment variables, mounted files, and controlled updates.
Kubernetes
Manage Kubernetes Resources and Autoscaling
Configure CPU and memory requests and limits, inspect metrics, and autoscale a Kubernetes Deployment with HPA.
Kubernetes
Route Kubernetes Traffic with Ingress
Route host- and path-based HTTP traffic through the prepared ingress-nginx controller to multiple Kubernetes Services.
Kubernetes
Control Kubernetes Traffic with Network Policies
Apply default-deny and selective Kubernetes NetworkPolicies using Pod and namespace labels, then verify allowed and blocked traffic.
Kubernetes
Inspect Kubernetes Resources with kubectl
Build a precise Kubernetes inspection workflow using namespaces, selectors, structured output, ownership data, and events.
Kubernetes
Run Kubernetes Jobs and CronJobs
Run finite and scheduled Kubernetes work with Jobs, parallel completions, CronJobs, history controls, and safe reruns.
Kubernetes
Deploy Node Services with Kubernetes DaemonSets
Deploy and update a Kubernetes DaemonSet while learning node eligibility, controller ownership, and one-Pod-per-node behavior.
Kubernetes
Run Stateful Applications with Persistent Storage
Use StorageClasses, PersistentVolumeClaims, headless Services, and StatefulSets to preserve data and stable Pod identity.
Kubernetes
Schedule Kubernetes Pods on Specific Nodes
Control Kubernetes Pod placement with node labels, nodeSelector, required and preferred affinity, taints, and tolerations.
Kubernetes
Troubleshooting Workloads
In this lab, you will learn how to troubleshoot Kubernetes workloads by debugging a failing Pod. You will deploy a Pod with a configuration error, identify the issue using status checks and events, and fix it to restore the workload.
KubernetesLinux
Secrets and ConfigMaps
In this lab, you will learn how to manage configuration and sensitive data in Kubernetes using ConfigMaps and Secrets. You will decouple configuration from code and securely inject secrets into Pods.
KubernetesLinuxCybersecurity
Understanding Pods
In this lab, you will learn the fundamental concept of Kubernetes Pods by creating, deploying, and inspecting a simple Nginx Pod.
KubernetesLinux
RBAC Authorization
In this lab, you will learn how to secure a Kubernetes cluster using Role-Based Access Control (RBAC). You will create Roles and RoleBindings to define permissions and assign them to users.
KubernetesLinuxCybersecurity
Deployments for Scaling
In this lab, you will learn how to create a Kubernetes Deployment, manage replicas, and observe self-healing capabilities.
KubernetesLinux
Interacting with Pods
In this lab, you will learn debugging basics in Kubernetes by interacting with running Pods. You will view logs, execute commands inside containers, and forward ports.
