Kubernetes Training from Basic to Advanced | 20+ ISSUE LIST

Discover how Rancher, an open source tool, manages multiple Kubernetes clusters from a single dashboard. Learn to install Rancher with Docker, connect clusters, and monitor pods, nodes, and alerts.

Learn how Rancher streamlines Kubernetes cluster management, including deploying pods with persistent volumes backed by an Azure disk and persistent volume claims, and configuring alerts for production environments.

Explain how private repositories store images and how Kubernetes pulls from private registries or Docker Hub, plus deploying pods via YAML and pushing images to a registry with authentication.

Learn to deploy private repository images by updating deployment manifests, pushing images to the private registry, and resolving image pull back errors with Docker registry secrets.

Learn how persistent volumes, persistent volume claims, and storage classes work together in Kubernetes, using Azure disk as the example, to provision and attach storage for pods.

Create storage class and PVCs, troubleshoot pending PVCs using describe, and understand reclaim policies. Extend PVC sizes by enabling allow volume expansion and updating the storage class.

Master Velero for backup and restoration in Kubernetes by configuring Azure storage, service principal credentials, and plugins, then perform on-prem to Azure managed cluster migration with restore workflows.

Master Velero backup tool workflows in Kubernetes by configuring backup locations, managing storage accounts and buckets, scheduling backups, and performing restoration across namespaces with troubleshooting and permissions guidance.

Discover the AKS cluster upgrade process, including pre and post tasks, using get upgrade, migrating pods to a temporary node, and planning for minimal downtime and backups.

Explore how to upgrade AKS clusters amid quota limits and node scaling. Learn safe pod migration using cordon, drain, and taints, plus handling PDB and memory issues.

Explore how to expose Kubernetes apps outside the cluster using Cluster IP, NodePort, and LoadBalancer, then deploy Nginx ingress controller with Helm and ingress rules.

Install and configure the Nginx ingress controller with helm, define ingress objects, and expose apps (Jenkins, Tomcat) via a load balancer and DNS records in Kubernetes.

Configure an ingress controller with a static IP. Obtain ssl certificate by generating a csr with OpenSSL and loading it as a tls secret for the ingress to enable https.

Learn how the horizontal pod autoscaler automatically scales pods in response to traffic, using threshold-based rules to adjust min and max replicas without manual intervention.

Troubleshoot live Kubernetes production issues by validating image paths and tags in deployment yaml, ensuring private registry access, and creating image pull secrets for Azure container registry authentication.

Troubleshoot image pull back errors in a Kubernetes production environment by inspecting container registry details in Azure Container Registry, validating repository and tag availability, and applying image pull secrets.

Diagnose a downed Kubernetes Tomcat app by checking pod status, image tag validity, service availability, and label-selector alignment, then review logs and fix deployment to restore the URL.

Learn live troubleshooting in a Kubernetes production env by diagnosing pod pending and crash loop backoff, exploring node resource limits, and adjusting deployments to restore web app access.

Diagnose a Kubernetes production issue by tracing a pending PVC caused by node affinity zone conflicts, then align PV and PVC in the same zone.

Troubleshoot Kubernetes production issues by validating YAML, creating the necessary namespace, inspecting pods with describe and logs, and increasing memory limits in the deployment to resolve crash loop back off.

Identify how to delete a PVC stuck in terminating state in a specific namespace by applying a finalizer merge command to permanently remove the associated persistent volume in production Kubernetes.

Learn live Kubernetes troubleshooting by diagnosing a pending pod, using kubectl describe to verify PVCs, and creating the PVC with the correct storage class to resolve the pending state.

Perform live troubleshooting of Kubernetes production pv and pvc issues by diagnosing storage class misconfigurations, such as a standard storage class not found causing pending pvc, and applying fixes.

Diagnose a pod stuck in pending by inspecting the pod manifest, the Nginx PVC, and node affinity issues; fix by recreating PV/PVC and aligning the zone with the storage class.

Learn live Kubernetes troubleshooting in production: validate clusters, check node status, use kubectl to manage pods and the Tomcat namespace, validate and apply yaml files.

Demonstrates live troubleshooting in a Kubernetes production environment, guiding learners from basic to advanced concepts through diagnosing and resolving production issues.

Learn how to extend a Kubernetes persistent volume by resizing the PVC from 3 GB to 4 GB, requiring downtime and pod restart, using Azure disk and YAML edits.

Learn to scale a Kubernetes cluster by adding a new worker node, using a scale set and instance counts, while monitoring pod distribution and node utilization.

Learn how to restrict pod scheduling to a specific worker node using node selector, node labeling, and deployment manifest updates in Kubernetes production environments.

Learn live troubleshooting for a Kubernetes production env by removing a namespace stuck in terminating state with kubectl patch to delete permanently using the finalizer.

Learn to delete all failed pods across the cluster with a single kubectl command using a field selector to filter status.phase=Failed, reducing manual cleanup and improving cluster performance.

Diagnose and fix an unavailable cluster by inspecting rancher pod status in the cattle-system namespace, adjusting the deployment replica from 0 to 1, and confirming the cluster becomes active.

Connects a jump box to a Kubernetes cluster in a production Azure setup, and demonstrates troubleshooting authentication issues using Azure CLI, Azure portal, and kubectl.

connect to a kubernetes production cluster from a jump box using the azure portal or azure cli. authenticate with az login and fetch credentials, then verify nodes with kubectl.

Deploy an application using yaml and check why no pod appears in the logging namespace. Review events to see a forbidden error from a missing daemonset service account.

Identify the root cause as a missing service account, create it in the logging namespace with proper labels, then apply and recreate resources to resolve the pod issue.

Watch a live devops interview on a GitHub‑driven CI/CD pipeline that builds Docker images and deploys to Azure Kubernetes clusters, including on‑premises, with RBAC, ingress, and Jenkins integration.

Guide learners through building and packaging a Kubernetes app, creating Docker images, Azure DevOps pipelines, and deploying with Kubernetes manifests to AKS, including SonarQube, service connections, and approvals.
