What is Kubernetes?
Kubernetes, also known as K8s, is an open source system for automating the deployment, scaling, and management of containerized applications. The name Kubernetes originates from Greek, meaning helmsman or pilot. In simple terms, think of K8s as the orchestrator for your container fleet. It tracks how many containers are needed, which one is performing well, and how to direct your traffic, among other things.
Here are some features provided by K8s:
- Load balancing and service discovery: Kubernetes exposes a container using an independent IP address or a DNS name. Kubernetes may load balance and spread the traffic to keep the deployment stable.
- Storage management: Kubernetes can allow you to mount storage, also called volume, that containers in the pods can read and write to; for example, on GKE you can mount volumes such as emptyDir, ConfigMap, Secret, and so on.
- Rollouts and rollbacks: Kubernetes does an automated rollout and rollback for you....
