Networking

Kubernetes expects us to establish a networking solution where all Node should be able to communicate to the Pods/Containers and all Pods should be able to communicate to all Nodes in the cluster.

There are several third-party solutions provided to us by third-party solutions 



When it comes to third-party networking solutions for Kubernetes (K8s) clusters, there are several robust options available. These solutions often integrate seamlessly with Kubernetes using the Container Network Interface (CNI) API. Here are a few notable ones:

  1. Calico: A popular choice for networking and network policy enforcement. It supports both overlay and non-overlay networks and provides flexibility for various deployment scenarios.

  2. Cisco ACI Networks :

  3. Cilium: Known for its eBPF-based data plane, Cilium offers advanced networking, observability, and security features. It can also replace kube-proxy for improved performance.

  4. Flannel: A simple and lightweight overlay network provider that works well for basic Kubernetes networking needs.

  5. Antrea: Operates at Layer 3/4 and leverages Open vSwitch for networking and security services.

  6. Multus: A multi-plugin that supports multiple network interfaces in Kubernetes pods, enabling the use of various CNI plugins.

  7. Contiv: Provides configurable networking options, including native Layer 3, overlay using VXLAN, and more.

Each of these solutions has its strengths and is suited for different use cases. If you'd like, I can help you explore any of these options in more detail!

Kubernetes - Components

Image
Kubernetes is built from several core components that work together to run and manage containerized applications. These components are usually grouped into: Control Plane Components (manage the cluster) Node Components (run workloads) 1️ .  Control Plane Components The control plane is responsible for managing the Kubernetes cluster. 1. kube-apiserver The API server is the entry point to the cluster . Everything in Kubernetes goes through it. Responsibilities Exposes the Kubernetes REST API Validates requests Processes CRUD operations for resources Communicates with the cluster datastore Example operations: Creating a Pod Scaling deployments Updating configurations Flow example:   User → kubectl → API Server → etcd   Key points: Stateless Can be horizontally scaled All components talk to it   2. etcd   etcd is the key-value database of Kubernetes.   It stores all cluster state.   Stores ...
