Quick Recap

Here are the key concepts we have learned so far:

Cluster and Kubernetes

A cluster is a group of machines that work together.

Kubernetes is a container orchestration tool that helps manage these machines.

A node is simply a machine.

A pod runs one or more containers.

A service is a way to expose an application running in a pod to the outside world.

Replica Sets manage the number of replicas of a pod running at any given time.

Deployments control the Replica Sets, allowing versioning and scaling of applications.

Now let's understand the architecture of Kubernetes.
