Introduction<\/b><\/h1>\n

As organizations adopt microservices, cloud-native applications, and DevOps practices, managing hundreds or even thousands of containers manually becomes challenging. While Docker simplifies application packaging through containers, it does not provide comprehensive capabilities for managing containerized applications at scale.<\/span><\/p>\n

Definition<\/b><\/h1>\n

Kubernetes<\/b> is an open-source container orchestration platform that automates the deployment, scaling, networking, monitoring, and lifecycle management of containerized applications.<\/span><\/p>\n

Architecture\u00a0<\/b><\/h1>\n

\u00a0\u00a0\u00a0 \"\"<\/b><\/p>\n

Working<\/b><\/h1>\n

Step 1: Create a Container Image<\/span><\/p>\n

Step 2: Push Image to Registry<\/span><\/p>\n

Step 3: Create Deployment YAML\u00a0<\/span><\/p>\n

Step 4: Deploy Application<\/span><\/p>\n

Step 5: Scheduler Assigns Pods<\/span><\/p>\n

Step 6: Pods Start Running\u00a0<\/span><\/p>\n

Step 7: Expose Application<\/span><\/p>\n

Step 8: Auto Scaling & Self-Healing<\/span><\/p>\n

Advantages<\/b><\/h1>\n
    \n
  1. Automatic Scaling Scales applications up or down based on demand.<\/span>\n

    <\/span><\/li>\n

  2. Self-Healing Automatically restarts failed containers and replaces unhealthy Pods.<\/span>\n

    <\/span><\/li>\n

  3. High Availability Distributes workloads across multiple nodes to reduce downtime.<\/span>\n

    <\/span><\/li>\n

  4. Load Balancing Balances incoming traffic across healthy Pods.<\/span>\n

    <\/span><\/li>\n

  5. Rolling Updates Deploy new versions with minimal or no downtime.<\/span>\n

    <\/span><\/li>\n

  6. Efficient Resource Utilization Optimizes CPU and memory usage across the cluster.<\/span>\n

    <\/span><\/li>\n

  7. Cloud Agnostic Runs on AWS, Azure, Google Cloud, and on-premises environments.<\/span>\n

    <\/span><\/li>\n

  8. Declarative Configuration Infrastructure and application state can be defined as code using YAML manifests.<\/span>\n

    <\/span><\/li>\n<\/ol>\n

    Disadvantages<\/b><\/h1>\n
      \n
    1. Steep Learning Curve Kubernetes concepts and components require time to master.<\/span>\n

      <\/span><\/li>\n

    2. Complex Setup Self-managed clusters require planning, networking, and security configuration.<\/span>\n

      <\/span><\/li>\n

    3. Resource Overhead The control plane and supporting services consume compute resources.<\/span>\n

      <\/span><\/li>\n

    4. Troubleshooting Complexity Diagnosing issues across multiple nodes and services can be challenging.<\/span>\n

      <\/span><\/li>\n

    5. Security Management Requires careful configuration of RBAC, network policies, and secrets.<\/span>\n

      <\/span><\/li>\n<\/ol>\n

      Interview Questions<\/b><\/h1>\n

      Basic<\/b><\/h3>\n
        \n
      1. What is Kubernetes?<\/b>
        \n<\/b> Kubernetes is an open-source platform for automating the deployment, scaling, and management of containerized applications.<\/span><\/li>\n
      2. What is a Pod?<\/b>
        \n<\/b> A Pod is the smallest deployable unit in Kubernetes and can contain one or more containers.<\/span><\/li>\n
      3. What is kubectl?<\/b>
        \n<\/b> kubectl<\/span> is the command-line tool used to interact with Kubernetes clusters.<\/span><\/li>\n
      4. What is a Deployment?<\/b>
        \n<\/b> A Deployment manages the desired number of Pod replicas and supports rolling updates and rollbacks.<\/span><\/li>\n
      5. What is a Service in Kubernetes?<\/b>
        \n<\/b> A Service provides a stable network endpoint for accessing one or more Pods.<\/span><\/li>\n<\/ol>\n

        Conclusion<\/b><\/h1>\n

        Kubernetes has become the backbone of modern cloud-native application deployment by providing automated container orchestration, scalability, resilience, and high availability. Combined with Docker, CI\/CD pipelines, and Infrastructure as Code tools, Kubernetes enables organizations to build reliable, secure, and highly scalable applications.<\/span><\/p>\n
