By the end of week 4, students will have a good understanding of how to work with multi-container applications and how to simplify their deployment using Docker Compose. The hands-on exercise will give them practical experience working with multi-container applications, and this will prepare them for next weeks where they will learn how to use orchestration tools like Kubernetes to manage the deployment of multi-container applications at scale.
Week 5: Introduction to Kubernetes
Overview of Kubernetes and its components: Explain what Kubernetes is, its main components such as Pods, Services, Replication Controllers, etc. and how they work together.
Understanding the role of Kubernetes in container orchestration: Discuss the benefits of using Kubernetes, such as scaling, failover, and service discovery.
Hands-on exercise: Deploying a multi-container application to a Kubernetes cluster: Provide instructions on how to deploy a multi-container application to a Kubernetes cluster using manifests, including creating pods, services, and deployments, and how to configure and access the application.
Weekly Objectives

By the end of week 5, students will have a good understanding of how to use Kubernetes for container orchestration, its components and how it works. The hands-on exercise will give them practical experience working with Kubernetes and deploying multi-container applications, this will prepare them for next weeks where they will learn how to use infrastructure as code tools to deploy and manage Kubernetes clusters.
Week 6: Extended Kubernetes Concepts Part 1
Introduction to Service Mesh: Explain what a Service Mesh is, its main components, and its role in improving service communication and security in a Kubernetes cluster.
Understanding Ingress and Kubernetes Services: Discuss the role of Ingress and Kubernetes Services in routing traffic to pods within a cluster, and how to configure and use them.
Understanding Volumes and VolumeMounts: Explain the role of Volumes and VolumeMounts in providing persistent storage for pods, and how to configure and use them.
Introduction to Operators and Service Accounts: Explain what Operators and Service Accounts are, and how they can be used to automate and manage complex applications and to provide specific permissions and access controls to pods.
Introduction to Helm: Explain what Helm is and how it can be used as a package manager for Kubernetes to manage, install, and upgrade applications and resources.
