Deploy nginx with Kubernetes Cluster Installation through Kubeadm

First we need to create 2 EC2 instances i.e t2 medium for master node and t2 micro for worker node. And allow ports for their connection. Run all below command on both master and worker nodes sudo apt update -y sudo apt install docker.io -y sudo systemctl start docker sudo systemctl enable docker sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list sudo apt update -y sudo apt install kubeadm=1.20.0-00 kubectl=1.20.0-00 kubelet=1.20.0-00 -y Run these commands on the master node. sudo su kubeadm init mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config kubectl apply -f https://github.com/weaveworks/weave/releases/download/v2.8.1/weave-daemonset-k8...

Accessing an EC2 Instance in a Private Subnet from a Public Subnet Instance on AWS

When setting up a complex network architecture on Amazon Web Services (AWS), you might need to establish communication between instances located in different subnets. One common scenario involves accessing an EC2 instance located in a private subnet from another EC2 instance located in a public subnet. In this blog, we'll guide you through the steps to achieve this setup using Linux instances. We'll leverage AWS VPC (Virtual Private Cloud) capabilities to securely access a private subnet instance from a public subnet instance. **Table of Contents:** 1. **Understanding the Architecture** 2. **Creating a Virtual Private Cloud (VPC)** 3. **Setting Up Subnets** 4. **Launching EC2 Instances** 5. **Configuring Security Groups** 6. **Establishing SSH Key Pairs** 7. **Enabling Traffic Routing** 8. **Accessing Private Subnet EC2 Instance** **1. Understanding the Architecture:** In this scenario, you'll have a Virtual Private Cloud (VPC) with two subnets: a public subnet and a priv...

Step-by-Step Guide: Connecting Jenkins Master and Agent via SSH and Deploying Nginx

Launch EC2 Instances : Start by launching two EC2 instances on AWS. One will serve as the master node, and the other as the agent node. Install Jenkins and Java on Master : SSH into the master instance and install Jenkins and Java. You can follow the official Jenkins documentation for installation instructions. Install Java on Agent : Similarly, SSH into the agent instance and install Java. Ensure that the same version of Java is installed on both the master and agent nodes. Generate SSH Key Pair : On the master node, generate an SSH key pair using the ssh-keygen command. This will create a public and private key pair. Authorize Agent : Copy the public key generated on the master node ( ~/.ssh/id_rsa.pub ) and paste it into the authorized_keys file on the agent node. This allows the master node to authenticate with the agent node via SSH. Open Port 8080 : In the security group settings for both EC2 instances, open port 8080 to allow inbound traffic for Jenkins.
