Course Overview

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF). Here are some key concepts and components related to Kubernetes:

1. Containers: Kubernetes is designed to work with containers, which are lightweight, isolated environments that encapsulate an application and its dependencies. Containers allow for consistent deployment across different environments.

2. Nodes: A node is a physical or virtual machine that serves as the worker machine in a Kubernetes cluster. Nodes are responsible for running containers and are managed by the cluster's control plane.

3. Cluster: A cluster is a group of nodes that work together to run containerized applications. It consists of a master node and multiple worker nodes. The master node manages and controls the cluster, while the worker nodes run the application containers.

4. Control Plane: The control plane is responsible for managing the cluster and its components. It includes several key components:

   • API Server: The API server acts as the control plane's front-end, allowing users and external components to interact with the cluster.

   • Scheduler: The scheduler assigns work (containers) to worker nodes based on resource availability and other constraints.

   • Controller Manager: The controller manager oversees various controllers that monitor the state of the cluster and perform tasks to maintain the desired state.

   • etcd: etcd is a distributed key-value store that stores the cluster's configuration data and represents the single source of truth for the cluster's state.

5. Pods: A pod is the smallest deployable unit in Kubernetes. It represents one or more containers that are tightly coupled and share the same resources, such as network and storage. Pods are scheduled onto nodes and can be horizontally scaled.

6. Services: Services enable network connectivity and load balancing for a set of pods. They provide a stable network endpoint for accessing pods, even as pods are added or removed.

7. Deployments: Deployments are a higher-level abstraction that manage the lifecycle of pods. They allow you to define the desired state of your application, including the number of replicas, and handle rolling updates and rollbacks.

8. Persistent Volumes (PV) and Persistent Volume Claims (PVC): PVs and PVCs are used to provide persistent storage to applications running in Kubernetes. PVs represent a physical storage resource, while PVCs are requests for specific storage resources by pods.

9. Namespaces: Namespaces provide a way to divide a cluster into virtual clusters, allowing multiple teams or projects to share the same physical infrastructure while maintaining isolation.

These are just a few key concepts and components in Kubernetes. Kubernetes provides a rich set of features and functionalities for managing containerized applications at scale. It has become a popular choice for deploying and managing applications in a cloud-native environment.

What is Kubernetes and what is it used for?

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.

Kubernetes simplifies the management and scaling of containerized applications, promotes automation, and enhances the reliability and availability of applications in cloud-native and hybrid environments.
