  • Deployments and Rollback
  • Setting resource limits
  • Kubernetes autoscaling

Week 5: Kubernetes Networking

• Kubernetes Networking
  • Ingress resources (LoadBalancer, Service)
  • Network Policies
  • Kubernetes CNI plugins
• Advanced Kubernetes Concepts
  • Names and name resolution
  • DaemonSet
  • Labels and Selectors

  • Continuous Deployment
  • Jenkins CI/CD in the context of Kubernetes
• Setting Up Kubernetes with Jenkins
  • Configuring and setting up a Kubernetes cluster using Jenkins CI/CD pipelines
  • Building and deploying applications from source code repositories automatically on a schedule

Week 7: Kubernetes Advanced Topics

• Advanced Kubernetes Concepts
  • Networking
  • Security Policies (SPs)
  • Service Accounts (SA)
  • Role-Based Access Control (RBAC)
  • Kubernetes CNI plugins
  • Autoscaling
  • Horizontal Pod Autoscaling (HPA)
  • Vertical Pod Autoscaling (VPA)

Week 8: Real-time CI/CD Projects with Kubernetes and Jenkins

• Real-time CI/CD Projects
  • Deploying an application from source code repositories to a Kubernetes cluster using Jenkins CI/CD pipelines
  • Managing, monitoring, and scaling the application as per the business requirements and technical specifications
  • Performing automated rollback in case of any failure or bug

Week N: Setting Up A Full-Stack Production-Grade CI/CD Pipeline with Jenkins, Docker, Kubernetes

• Understanding Full-Stack CI/CD Pipelines
  • Definition and Explanation
  • Components Involved in a Full-Stack CI/CD Pipeline (Codebase), Build Server (BSS)
  • Staging and Production Environments
  • Container Orchestration with Kubernetes

Final Week: Real-world Application Deployment

• Real-time Projects
  • Designing a real-world application deployment process
  • Implementing CI/CD pipelines for the application using Jenkins, Docker, and Kubernetes in a production-grade environment
  • Automation of application development, testing, building, deploying, monitoring, logging, degradation, scaling, rollback, and recovery operations

Throughout this learning path, you will engage with hands-on labs and real-world scenarios to apply the theoretical knowledge into practical experience. This comprehensive approach will ensure that you are not only understanding Docker, Kubernetes, and Jenkins CI/CD but also becoming proficient in setting up production-grade containerized orchestrated applications using these powerful technologies.
