In this video, you'll learn:

1. GitHub Webhooks Integration:
- How to configure webhooks in GitHub to trigger Jenkins builds automatically when code is pushed.

2. Dockerfile and Docker Image Creation:
- How to write a Dockerfile for your application and build a Docker image that will be used in your Kubernetes deployment.
- Pushing the Docker image to DockerHub for seamless integration into your pipeline.

3. Ansible Automation for Infrastructure Setup:
- Using Ansible for automating infrastructure provisioning and configuring the environment for Kubernetes deployments.

4. Kubernetes NodePort Service:
- Learn how to create a NodePort service in Kubernetes to expose your application externally and access it globally.

5. Kubernetes ReplicaSet:
- Setting up a Kubernetes ReplicaSet to ensure high availability and scalability of your application.

6. Jenkins Pipeline for CI/CD:
- Building a fully automated Jenkins pipeline that integrates all steps: code commit, Docker image build, Ansible automation, and Kubernetes deployment.

Key Features Covered:
- Webhook Integration: Automate build triggers with GitHub and Jenkins.
- Docker Automation: Build and push Docker images using DockerHub.
- Kubernetes Deployments: Deploy and scale applications using ReplicaSets and NodePort.
- Ansible Scripting: Automate infrastructure and deployment tasks with Ansible.

By the end of this video, you’ll be able to set up an automated DevOps pipeline that manages application deployment on Kubernetes using Jenkins, Ansible, Docker, and GitHub. Perfect for DevOps engineers, developers, and system administrators!

Useful Commands & Resources:
- Sample Dockerfile and Ansible playbooks
- Kubernetes YAML files for NodePort service and ReplicaSet configurations
