Kubernetes is designed to automate the deployment, scaling, and operation of application containers. The architecture is divided into two main components: 𝙈𝙖𝙨𝙩𝙚𝙧 and 𝙒𝙤𝙧𝙠𝙚𝙧. Here’s a detailed breakdown:

🔶𝙈𝙖𝙨𝙩𝙚𝙧 𝙉𝙤𝙙𝙚 𝘾𝙤𝙢𝙥𝙤𝙣𝙚𝙣𝙩𝙨:
The master node is the brain of the Kubernetes cluster, responsible for managing the state and orchestrating the cluster.

𝟭) 𝗞𝘂𝗯𝗲-𝗔𝗣𝗜 𝗦𝗲𝗿𝘃𝗲𝗿:

•Acts as the front-end for the Kubernetes control plane.
•Exposes the Kubernetes API, which is the primary entry point for all administrative operations on the cluster.

𝟮) 𝗲𝘁𝗰𝗱:

•A distributed key-value store used to store all cluster data.
•Ensures consistency and high availability of data across the cluster.

𝟯) 𝗞𝘂𝗯𝗲-𝗦𝗰𝗵𝗲𝗱𝘂𝗹𝗲𝗿:

•Assigns newly created pods to nodes based on resource requirements, policies, and constraints.
•Ensures optimal resource utilization.

𝟰) 𝗞𝘂𝗯𝗲-𝗖𝗼𝗻𝘁𝗿𝗼𝗹𝗹𝗲𝗿-𝗠𝗮𝗻𝗮𝗴𝗲𝗿:

•Runs various controller processes to regulate the state of the cluster.
•Includes node controller, replication controller, endpoints controller, and more.

🔶𝙒𝙤𝙧𝙠𝙚𝙧 𝙉𝙤𝙙𝙚 𝘾𝙤𝙢𝙥𝙤𝙣𝙚𝙣𝙩𝙨
Worker nodes (also known as slave nodes) are responsible for running the actual applications (containers) in the pods.

𝟭) 𝗞𝘂𝗯𝗲𝗹𝗲𝘁:

•An agent that runs on each worker node.
•Ensures that containers are running in a pod and reports back to the master node.

𝟮) 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗣𝗿𝗼𝘅𝘆 (𝗞𝘂𝗯𝗲-𝗣𝗿𝗼𝘅𝘆):

•Manages network rules on each node.
•Facilitates networking and communication between pods and services inside or outside the cluster.
•Provides load balancing and network traffic routing for services.

🔶𝙐𝙨𝙚𝙧 𝙄𝙣𝙩𝙚𝙧𝙖𝙘𝙩𝙞𝙤𝙣
•Users interact with the Kubernetes cluster using the kubectl command-line tool.
•kubectl communicates with the API Server to perform various operations like deploying applications, scaling them, and managing cluster resources.

🔶𝙉𝙚𝙩𝙬𝙤𝙧𝙠𝙞𝙣𝙜
•The CNI (Container Network Interface) network, such as Weave Net or Calico, provides the necessary networking capabilities for communication between pods across different nodes in the cluster.

This architecture ensures that Kubernetes can manage and orchestrate containerized applications efficiently, providing high availability, scalability, and reliability. Understanding these components is crucial for anyone working with Kubernetes.

I believe this blog will be really helpful, giving you fresh perspectives and teaching you something new and interesting. 🙏

😊 Happy Kubernetes!
