Kubernetes Architect

Today I learnt Kubernetes Architect

• Control Plane (Master Node) → 1)

1. API Server (exposes to external world)
2. Scheduler (Scheduling pods or resources in K8s)Receives information from API server
3. etcd: Backup service (key value store)
4. Controller Manager Example: Replica Set
5. CCM (Cloud Controller Manager)
   • No need for on-premise

• Data plane (Worker Node) → 3 components:

1. Kubelet (Creating and managing pod)
2. Kube Proxy (uses iptables in Linux machine)
3. Container Runtime (environment)
