AWS EKS Kubernetes-Masterclass | DevOps, Microservices

Explore how Docker solves traditional infra problems by packaging apps into portable containers and images, using the Docker daemon, client, and registry for consistent, scalable deployments across environments.

Build a custom nginx Docker image locally, test it on port 80, and push to Docker Hub using a Dockerfile, tagging, and verification steps.

Master essential docker commands for managing images and containers, including ps, stop, run, remove, pull, and exec. Learn to login, view stats, and connect to a container terminal.

Launch and inspect a Kubernetes pods demo with kubectl, verify node readiness, create a pod from a public image, and describe the pod to review its ip and events.

Delete pods and services with kubectl delete and verify cleanup with kubectl get all in the default namespace, practicing step-by-step pod and service removal.

Expose a Kubernetes replica set as a node-port service and access the hello world app in a browser; demonstrate reliability, scaling, and the role of labels and selectors.

Update Kubernetes deployments with kubectl set image and verify rollout status and pod replacement. Compare rolling update versus recreate strategy and review rollout history to understand deployment behavior.

Learn how Kubernetes services enable internal and external access with cluster ip, node port, load balancer, ingress, and external name, and see front end and back end use cases.

Create and deploy a ReplicaSet using a YAML definition, verify the replicas and template, and prepare a NodePort service to access the app in the browser.

Write Kubernetes YAML manifests for a backend deployment and cluster IP service, then deploy, test, and verify end-to-end connectivity from the frontend, moving from imperative commands to declarative workflows.

Explore the EBS CSI driver's features, including dynamic and static provisioning, block volumes, and volume snapshots. Understand beta and alpha states and how to enable storage class expansion.

Create the user management microservice deployment and a kubernetes node port service manifest, wiring the environmental variables to connect to the mysql database and reuse prior storage components.

Test the user management microservice in the AWS EKS Kubernetes masterclass using Postman by importing the collection, configuring the environment, and performing create, list, update, and delete operations.

Explore Kubernetes probes—liveness, readiness, and startup—and how kubelet uses them to restart containers, control traffic, and handle slow-start apps, with command, http get, or tcp socket checks.

Set resource requests and limits for containers to guide scheduling and enforce bounds with the kubelet, using 500m cpu and 128mi memory as examples. Explore horizontal, vertical, and cluster autoscaling to handle high traffic and capacity.

Discover how Kubernetes namespaces act as virtual clusters that isolate objects, enabling multi-team environments, with default and system namespaces like kube-system, and per-namespace resource quotas.

Demonstrate deploying classic load balancers on Kubernetes, compare AWS load balancer types, and configure Kubernetes services to expose apps via public subnets and DNS URL, with SSL and 80–443 redirection.

Learn to deploy a network load balancer (NLB) in AWS EKS by applying a Kubernetes service manifest with NLB annotations, validate TCP-based load balancing and health status endpoints.
