Kubernetes (K8s) is an open-source container orchestration platform designed to automate the deployment, scaling, and management of containerized applications. Its workflow involves several key components and processes:<\/p>\n\n\n

Certainly! Let’s dive deeper into each step of the Kubernetes deployment workflow:<\/p>\n\n\n

    \n
  1. User Deployment:<\/strong>\n
      \n
    • The user creates a Kubernetes manifest file, typically written in YAML or JSON format, to define the desired state of the application.<\/li>\n\n\n
    • The manifest includes specifications for various Kubernetes resources, such as Pods, Deployments, Services, ConfigMaps, Secrets, and PersistentVolumes.<\/li>\n\n\n
    • The user specifies details such as container images, resource requirements (CPU and memory), networking settings, environment variables, and volumes for data persistence.<\/li>\n<\/ul>\n<\/li>\n\n\n
    • Manifest Submission:<\/strong>\n
        \n
      • The user submits the manifest file to the Kubernetes API server, which is the primary management point for the Kubernetes cluster.<\/li>\n\n\n
      • This can be done using the kubectl apply -f <manifest-file><\/code> command or through API calls to the Kubernetes API server.<\/li>\n\n\n
      • The API server validates the manifest file and processes the submitted configuration details.<\/li>\n<\/ul>\n<\/li>\n\n\n
      • Storage in etcd:<\/strong>\n
          \n
        • The API server stores the configuration details provided in the manifest file into etcd, which is a distributed key-value store.<\/li>\n\n\n
        • Etcd serves as the source of truth for the Kubernetes cluster’s state and configuration data.<\/li>\n\n\n
        • Configuration changes, such as deployments, services, and updates to existing resources, are persisted in etcd to maintain consistency across the cluster.<\/li>\n<\/ul>\n<\/li>\n\n\n
        • Controller Manager:<\/strong>\n
            \n
          • The Controller Manager is a Kubernetes control plane component responsible for managing various controllers that regulate the state of the cluster’s resources.<\/li>\n\n\n
          • Controllers include the ReplicaSet controller, Deployment controller, StatefulSet controller, DaemonSet controller, and others.<\/li>\n\n\n
          • When a new deployment is submitted or updates are made to existing resources, the Controller Manager detects changes in the desired state and initiates reconciliation processes.<\/li>\n\n\n
          • The Controller Manager ensures that the actual state of the cluster matches the desired state specified in the manifests.<\/li>\n<\/ul>\n<\/li>\n\n\n
          • Kubelet Action:<\/strong>\n
              \n
            • The Kubelet is an agent that runs on each worker node in the Kubernetes cluster.<\/li>\n\n\n
            • It communicates with the API server and receives instructions from the Controller Manager to manage containers’ lifecycle on its node.<\/li>\n\n\n
            • Upon receiving instructions, the Kubelet interacts with the container runtime (e.g., Docker, containerd) to create, start, stop, or delete containers based on the desired state defined in the manifests.<\/li>\n<\/ul>\n<\/li>\n\n\n
            • Kube Proxy:<\/strong>\n
                \n
              • Kube Proxy is a network proxy that runs on each node in the Kubernetes cluster.<\/li>\n\n\n
              • It manages network connectivity and routing for pods within the cluster.<\/li>\n\n\n
              • Kube Proxy maintains network rules, such as iptables rules or IPVS rules, to enable pod-to-pod communication, load balancing, and service discovery.<\/li>\n\n\n
              • It ensures that incoming traffic is properly routed to the appropriate pods and that outgoing traffic from pods is appropriately handled.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n
