I want to know about kubernetes components I have been studying kubernetes for a while and I want to understand that.

Is kubernetes a deployment run inside container? or it's just control plane process?

CodePudding user response：

Kubernetes is a container orchestrator. It consists of several components (e.g. several processes) that typically runs on several servers, a control plane part and workload nodes.

1. Kubernetes is a container orchestrator, so it operates containers. You can tell Kubernetes what/how/how much are the containers to be deployed to implement your application service. We usually use YAML declaration to tell Kubernetes what to do, and Kubernetes figures out how to do it for us, so we don't need hundreds of shell scripts, which is especially a hard work when we are facing a big cluster.
2. So, Kubernetes is a "system". The control plane is one part of the system, and is not only 1 process, but composed of many processes (the process can be also inside container), e.g., etcd database, scheduler, controller manager, and API-server, etc.
