Advanced Kubernetes, GKE and EKS - All that we need to Know

Learn how containers bundle OS libraries, dependencies, and applications into self-contained, portable units that remove host OS dependencies, enabling platform-agnostic, scalable microservices via a container registry.

Install docker engine on Windows using WSL2 Ubuntu 20.04, configure prerequisites, add docker apt repository, install and start docker, verify with pull and images, and preview building custom images.

Master docker commands and dockerfile instructions to build container images, using from, copy, workdir, environment variables, and entrypoint, plus docker build, login, pull, push, and run.

Docker commands by building a docker image with docker build from a dockerfile with openjdk 19 on Oracle Linux 8.6, then create, start, and run containers to verify Java version.

Explore how Kubernetes automates container deployment, scaling, and self-healing across master and worker nodes, using api server, scheduler, and controllers to manage pods and secrets.

Create a single-node kubernetes cluster with minikube on Windows or Linux, use Docker driver, deploy a service and deployment, perform port forwarding to access the app, and delete the cluster.

Learn to deploy applications to a Kubernetes cluster by using namespaces and deployments, with manifest files applied via kubectl to manage replicas, containers, and resources.

Learn how Kubernetes services group ports with a selector to expose apps via cluster IP, node port, or DNS, and how endpoint slices and IP tables enable routing and balancing.

Explore kubernetes architecture, tracing how the api server fronts the cluster, stores state in etcd, and coordinates controllers, scheduler, kubelet, and kube-proxy to manage deployments, services, and endpoint slices.

Explore Kubernetes volume types, focusing on emptyDir, shared across containers in a pod and mounted to /log where a Java job writes timestamps.

Explore hostpath volumes by mounting the host path as a Kubernetes volume, so logs persist after pod deletion, with per-machine storage or shared storage via a common mount.

Shows how to create a local storage persistent volume and a persistent volume claim, bind them, and deploy an app that mounts /log from the claim using a storage class.

Demonstrate how Kubernetes DNS resolves service names and how apps use environment variables to call other services via DNS. Deploy two apps and verify DNS resolution with a DNS util.

Learn how ingress in Kubernetes exposes external http and https endpoints, handles TLS termination and load balancing, and routes traffic to internal services via ingress controllers and rules.

Deploy the nginx ingress controller and configure a clusterIP service for the web app. Create an ingress with the nginx class and a path prefix to expose it.
