+### **1-Day Learning & Lab Activity Plan for IT Engineer: CI/CD, Jenkins, Kubernetes, GitOps**  
+*Focus Areas: CI/CD Concepts, Jenkins, Kubernetes Integration, GitOps Principles*  
+
+---
+
+### **Morning Session (9:00 AM – 12:30 PM)**  
+
+#### **1. Introduction to CI/CD Concepts (9:00 AM – 9:45 AM)**  
+**Objective**: Understand core CI/CD principles and workflows.  
+- **Key Topics**:  
+  - What is CI/CD? Benefits (speed, reliability, automation).  
+  - CI/CD pipeline stages: Build → Test → Deploy → Monitor.  
+  - Differences between traditional deployment vs. CI/CD.  
+  - Tools overview (Jenkins, GitLab CI, GitHub Actions).  
+- **Activity**: Whiteboard a sample CI/CD pipeline for a web app.  
+
+---
+
+#### **2. Jenkins for CI/CD (9:45 AM – 11:00 AM)**  
+**Objective**: Set up Jenkins and create a basic CI/CD pipeline.  
+- **Key Topics**:  
+  - Jenkins architecture (master/agent, plugins).  
+  - Creating freestyle and pipeline jobs.  
+  - Integrating Jenkins with Git (GitHub/GitLab).  
+- **Lab Activity**:  
+  1. Install Jenkins on a local VM/cloud instance.  
+  2. Create a "Hello World" pipeline script (declarative syntax).  
+  3. Trigger a build on a Git commit (webhook setup).  
+  ```groovy
+  pipeline {
+    agent any
+    stages {
+      stage('Build') {
+        steps {
+          echo 'Building...'
+        }
+      }
+      stage('Test') {
+        steps {
+          echo 'Testing...'
+        }
+      }
+    }
+  }
+  ```  
+- **Troubleshooting**: Resolving plugin conflicts, agent connectivity.  
+
+**Break (11:00 AM – 11:15 AM)**  
+
+---
+
+#### **3. Jenkins CI/CD for Kubernetes (11:15 AM – 12:30 PM)**  
+**Objective**: Deploy applications to Kubernetes using Jenkins.  
+- **Key Topics**:  
+  - Kubernetes basics (pods, deployments, services).  
+  - Jenkins plugins for Kubernetes (Kubernetes CLI, Helm).  
+  - Dynamic Jenkins agents in Kubernetes pods.  
+- **Lab Activity**:  
+  1. Set up a local Kubernetes cluster (Minikube/kind).  
+  2. Configure Jenkins to deploy to Kubernetes:  
+     - Install Kubernetes plugin.  
+     - Add Kubeconfig to Jenkins credentials.  
+  3. Create a pipeline to build a Docker image and deploy to Kubernetes:  
+  ```groovy
+  pipeline {
+    agent any
+    stages {
+      stage('Build Docker') {
+        steps {
+          sh 'docker build -t my-app:latest .'
+        }
+      }
+      stage('Deploy to K8s') {
+        steps {
+          sh 'kubectl apply -f k8s-deployment.yaml'
+        }
+      }
+    }
+  }
+  ```  
+- **Challenge**: Diagnose a failed deployment (e.g., image pull error).  
+
+---
+
+### **Lunch Break (12:30 PM – 1:30 PM)**  
+
+---
+
+### **Afternoon Session (1:30 PM – 5:00 PM)**  
+
+#### **4. GitOps Principles (1:30 PM – 2:30 PM)**  
+**Objective**: Learn GitOps fundamentals and declarative infrastructure.  
+- **Key Topics**:  
+  - What is GitOps? (Git as the single source of truth).  
+  - Declarative vs. imperative infrastructure.  
+  - Tools: Argo CD, Flux, Jenkins GitOps integration.  
+- **Activity**: Compare CI/CD and GitOps workflows.  
+- **Lab Activity**:  
+  1. Declare a Kubernetes deployment manifest in a Git repo.  
+  2. Use Jenkins to sync the cluster state with the Git repo:  
+     - Poll Git for changes.  
+     - Automatically run `kubectl apply` on updates.  
+
+---
+
+#### **5. Jenkins + GitOps Lab (2:30 PM – 4:00 PM)**  
+**Objective**: Automate Kubernetes deployments using GitOps with Jenkins.  
+- **Lab Steps**:  
+  1. Fork a sample Git repo with Kubernetes manifests.  
+  2. Configure Jenkins to monitor the repo (SCM polling).  
+  3. Create a pipeline to apply changes:  
+  ```groovy
+  pipeline {
+    agent any
+    stages {
+      stage('Sync K8s') {
+        steps {
+          git url: 'https://github.com/your-repo.git', branch: 'main'
+          sh 'kubectl apply -f ./manifests/'
+        }
+      }
+    }
+  }
+  ```  
+  4. Modify a manifest in Git and observe Jenkins auto-deploying.  
+- **Discussion**: Security considerations (secrets management, RBAC).  
+
+**Break (4:00 PM – 4:15 PM)**  
+
+---
+
+#### **6. Recap, Q&A, and Feedback (4:15 PM – 5:00 PM)**  
+- Review key takeaways: CI/CD pipelines, Jenkins-Kubernetes integration, GitOps.  
+- **Q&A**: Common pitfalls (e.g., pipeline debugging, state drift in GitOps).  
+- **Feedback Session**: Adjust future content based on learner input.  
+- **Additional Resources**:  
+  - Jenkins Documentation: https://www.jenkins.io/doc/  
+  - GitOps Working Group: https://www.gitops.tech/  
+
+---
+
+### **Lab Environment Setup (Pre-requisites)**  
+- Jenkins server with Docker, Kubernetes plugins.  
+- Kubernetes cluster (Minikube, EKS, or GKE).  
+- Git repository (GitHub/GitLab) with sample code and manifests.  
+
+By the end of the day, learners will have built a Jenkins pipeline for Kubernetes deployments and implemented GitOps practices for infrastructure management.
