Building a Kubernetes Cluster on AWS EC2 Instances

Introduction: As a cloud enthusiast, I embarked on a journey to deepen my understanding of Kubernetes by building a cluster from scratch on AWS EC2 instances. In this article, I'll share the steps I took to create a Kubernetes cluster with two worker nodes and one control plane server, providing insights into the intricacies of the setup process. Prerequisites: Before diving in, make sure you have an AWS account, AWS CLI installed, and basic knowledge of AWS EC2 and networking. Step 1: Launching EC2 Instances: I started by launching three EC2 instances - one for the control plane and two for worker nodes. Selecting the appropriate Ubuntu Server AMI and instance types laid the foundation for the cluster. Step 2: Configuring EC2 Instances: Connecting to each instance via SSH, I updated the package list and installed necessary dependencies. This step ensured a clean environment for the subsequent Kubernetes components. Step 3: Installing Docker and Containerd: The installation of Docker and Containerd on each EC2 instance provided the container runtime necessary for Kubernetes. This step is crucial for the seamless execution of containerized applications. Step 4: Installing Kubernetes Components: Installing kubeadm, kubelet, and kubectl on all nodes was the next logical step. These components form the backbone of Kubernetes, enabling control and communication within the cluster. Step 5: Initializing the Control Plane: On the control plane node, I initiated the cluster using kubeadm init. The provided instructions guided me in setting up kubectl and joining nodes to the cluster. Step 6: Joining Nodes to the Cluster: Each worker node joined the cluster by executing the command generated during control plane initialization. This step seamlessly integrated the nodes into the Kubernetes ecosystem. Step 7: Installing a Network Plugin (Calico): To facilitate communication between pods in the cluster, I applied a network plugin, in this case, Calico. This was a crucial step in ensuring seamless networking within the Kubernetes cluster. Conclusion: Building a Kubernetes cluster from scratch on AWS EC2 instances provided a hands-on experience that deepened my understanding of container orchestration. The process involved not only technical know-how but also a problem-solving mindset.
