Kubernetes architecture consists of master/control plane components and worker nodes, working together to manage containerized applications. Here's a brief breakdown:

Control Plane (Master Node):

• API Server: Provides communication and control via the Kubernetes API.
• Scheduler: Distributes workloads (pods) among nodes according to the availability of resources.
• Controller Manager: Manages endpoints, replicas, and other control loops.
• etcd: A cluster configuration and state key-value store.
• Cloud Controller Manager: Connects cloud-specific services to Kubernetes.

Worker Nodes:

• Kubelet: Verifies that containers are operating as intended by running on each worker node.
• Kube-Proxy: Network rules are managed by Kube-Proxy to - - facilitate pod communication.
• Container Runtime: In charge of executing containers, such as Docker and containerd.

Additional Crucial Ideas:

• Pods: The smallest deployable units are called pods, which hold one or more containers.
• Nodes: Workload-running computers, either physical or virtual.
• Services: Load balancing pods and stable endpoints for exposure.
• Persistent Storage: Volumes for managing data over restarts are known as persistent storage.
• Namespaces: Multi-tenancy logical divisions.

To efficiently manage the cluster, Kubernetes makes use of declarative configurations and intended state reconciliation.
