Microservices architecture has gained popularity due to its scalability, flexibility, and resilience. Kubernetes, an open-source container orchestration platform, provides powerful tools for deploying and managing microservices at a scale. In this guide, we’ll walk through the process of deploying a microservices-based application on Kubernetes using PostgreSQL as the database. By following this step-by-step tutorial, readers will be able to deploy their own projects seamlessly.

The architecture of Kubernetes comprises several key components, each playing a vital role in managing and orchestrating containerized workloads. Here are the main components of Kubernetes architecture: 

Master Node:

1. API Server: The Kubernetes API server is a central component that acts as a frontend for the Kubernetes control plane. It exposes the Kubernetes API, which serves as the primary interface for managing and interacting with the Kubernetes cluster. The API server handles all API requests, including creating, updating, and deleting resources like pods, services, deployments, and more.
2. Scheduler: The scheduler is responsible for assigning pods to nodes based on resource requirements, quality of service requirements, and other constraints specified in the pod specification (PodSpec). It ensures optimal resource utilization and workload distribution across the cluster by considering factors like available resources, node affinity, and anti-affinity rules.
3. Controller Manager: The controller manager is a collection of control loops that continuously monitor the cluster’s state and reconcile it with the desired state defined in the Kubernetes resource objects. Each controller within the controller manager is responsible for managing a specific type of resource, such as nodes, pods, services, replication controllers, and endpoints. For example, the node controller ensures that the desired number of nodes are running and healthy, while the replication controller maintains the desired number of pod replicas.
4. etcd: etcd is a distributed key-value store that serves as the cluster’s database, storing configuration data, state information, and metadata about the Kubernetes cluster. It provides a reliable and consistent data store that allows Kubernetes components to maintain a shared understanding of the cluster’s state. etcd is highly available and resilient, using a leader-election mechanism and data replication to ensure data consistency and fault tolerance.

Node (Worker Node):

1. Kubelet: The kubelet is an agent that runs on each node in the Kubernetes cluster and is responsible for managing pods and containers on the node. It receives pod specifications (PodSpecs) from the API server and ensures that the containers described in the PodSpecs are running and healthy on the node. The kubelet communicates with the container runtime (e.g., Docker, containerd) to start, stop, and monitor containers, and reports the node’s status and resource usage back to the API server.
2. Kube-proxy: The kube-proxy is a network proxy that runs on each node and maintains network rules and services on the node. It implements the Kubernetes Service concept, which provides a way to expose a set of pods as a network service with a stable IP address and DNS name. The kube-proxy handles tasks such as load balancing, connection forwarding, and service discovery, ensuring that incoming network traffic is properly routed to the correct pods.
3. Container Runtime: The container runtime is the software responsible for running containers on the node. Kubernetes supports multiple container runtimes, including Docker, containerd, cri-o, and others. The container runtime pulls container images from a container registry, creates and manages container instances based on those images, and provides an interface for interacting with the underlying operating system’s kernel to isolate and manage container resources.

Understanding Microservices Architecture:

Microservices architecture deconstructs monolithic applications into smaller, self-contained services. Each service has its well-defined boundaries, database (optional), and communication protocols. This approach fosters:

• Loose coupling: Microservices interact with each other through well-defined APIs, minimizing dependencies and promoting independent development.
• Independent deployment: Services can be deployed, scaled, and updated independently without affecting the entire application, streamlining maintenance and innovation.
• Separate databases: Services can leverage their own databases (relational, NoSQL, etc.) based on their specific needs, enhancing data management flexibility.

Setting up Kubernetes cluster:

We can set up Kubernetes cluster using tools like Minikube, kubeadm, or cloud providers like AWS EKS, Google GKE, or Azure AKS.
