Kubernetes Overview
As containers gain popularity in organizations, Kubernetes emerges as the go-to software for managing them. It's like a control center for deploying and handling containerized apps, a crucial aspect of DevOps.
Initially created by Google and made open-source in 2014, Kubernetes draws from Google's 15-year experience in managing containerized tasks and inputs from the open-source community. It takes inspiration from Borg, Google's internal cluster management system.
What is Kubernetes? Write in your own words and why do we call it k8s?
Kubernetes, often shortened to K8s, is a tool that helps us manage applications.
We call it K8s because it's a fun way to abbreviate the name. It's like a conductor, organizing and coordinating containers, which are like mini-applications, across different computers.
What are the benefits of using k8s?
Kubernetes offers many advantages:
Efficient Use of Resources: It helps us use our computer resources wisely.
Scaling Applications: With Kubernetes, we can easily make our applications bigger or smaller as needed.
Keeping Applications Running: Kubernetes ensures that our applications stay up and running, even if parts of them fail.
Easy Setup: It's simple to tell Kubernetes how we want our applications to work.
Lots of Options: There are many extra things we can add to Kubernetes to make it even more useful.
Explain the architecture of Kubernetes
Kubernetes has two main parts:
Control Plane: This is like the brain of Kubernetes. It keeps track of everything and makes sure everything runs smoothly.
Worker Nodes: These are like the hands and feet of Kubernetes. They do the actual work of running our applications.
What is Control Plane?
The Control Plane is the most important part of Kubernetes. It decides how everything should work. It has many pieces, like the API server, scheduler, controller manager, and etcd.
These pieces talk to each other to make sure everything stays in the right place.
Write the difference between kubectl and kubelets.
Kubectl and kubelet are two important tools:
kubectl: It's a tool we use to tell Kubernetes what we want it to do.
kubelet: It's a tool that makes sure our applications keep running smoothly.
Explain the role of the API server.
- The API server is like a receptionist for Kubernetes. It listens to what we want and helps make it happen. It's how we talk to Kubernetes and tell it what to do.
