Introduction
- Kubernetes, often abbreviated as K8s, is an open-source platform designed for automating the deployment, scaling, and operation of application containers.
- Kubernetes helps manage clusters of containers, which can host applications and services. It automates the deployment, scaling, and management of containerized applications
Components:
- In a Kubernetes cluster, the two main components are:
- Control Plane (Master Node)
- Data Plane (Worker Node)
1.Control Plane (Master Node): This is the management and control center of the Kubernetes cluster
Key Components:
- API Server: Exposes the Kubernetes API, which is used to interact with the cluster.
- etcd: A distributed key-value store that stores the cluster’s configuration data.
- Controller Manager: Manages controllers responsible for maintaining the desired state of resources.
- Scheduler: Assigns work (containers) to nodes based on resource availability and constraints.
2. Data Plane (worker Node) This is where your application container
Key Components:
- Kubelet: Ensures containers are running in a Pod on the node.
- Kube Proxy: Maintains network rules on the node.
- Container Runtime: The software responsible for running containers (e.g., Docker, containerd).
