Kubernetes is designed to automate the deployment, scaling, and operation of application containers. The architecture is divided into two main components: đ™ˆđ™–đ™šđ™©đ™šđ™§ and đ™’đ™€đ™§đ™ đ™šđ™§. Here’s a detailed breakdown:

đŸ”¶đ™ˆđ™–đ™šđ™©đ™šđ™§ đ™‰đ™€đ™™đ™š đ˜Ÿđ™€đ™ąđ™„đ™€đ™Łđ™šđ™Łđ™©đ™š:
The master node is the brain of the Kubernetes cluster, responsible for managing the state and orchestrating the cluster.

𝟭) 𝗞𝘂𝗯đ—Č-𝗔𝗣𝗜 𝗩đ—Č𝗿𝘃đ—Č𝗿:

‱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.

𝟼) đ—Čđ˜đ—°đ—±:

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

𝟯) 𝗞𝘂𝗯đ—Č-đ—Šđ—°đ—”đ—Čđ—±đ˜‚đ—čđ—Č𝗿:

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

𝟰) 𝗞𝘂𝗯đ—Č-đ—–đ—Œđ—»đ˜đ—żđ—Œđ—čđ—čđ—Č𝗿-đ— đ—źđ—»đ—źđ—Žđ—Č𝗿:

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

đŸ”¶đ™’đ™€đ™§đ™ đ™šđ™§ đ™‰đ™€đ™™đ™š đ˜Ÿđ™€đ™ąđ™„đ™€đ™Łđ™šđ™Łđ™©đ™š
Worker nodes (also known as slave nodes) are responsible for running the actual applications (containers) in the pods.

𝟭) 𝗞𝘂𝗯đ—Čđ—čđ—Č𝘁:

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

𝟼) 𝗩đ—Čđ—żđ˜ƒđ—¶đ—°đ—Č đ—Łđ—żđ—Œđ˜…đ˜† (𝗞𝘂𝗯đ—Č-đ—Łđ—żđ—Œđ˜…đ˜†):

‱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.

đŸ”¶đ™đ™šđ™šđ™§ đ™„đ™Łđ™©đ™šđ™§đ™–đ™˜đ™©đ™žđ™€đ™Ł
‱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.

đŸ”¶đ™‰đ™šđ™©đ™Źđ™€đ™§đ™ đ™žđ™Łđ™œ
‱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!
