This repository contains a project where I’ve managed to create a Build & Deployment for a Node.js app

• AWS
• Git & GitHub
• Jenkins
• npm
• Jfrog
• Docker
• Kubernetes

• Step 1 - Create an instance named Jenkins-Server and login to the server. Make sure you open port 8080. Install git, install Java, and Jenkins in /opt, and access Jenkins GUI.
• Step 2 - Create an instance named Build-Server and login to the server. Install git, install Java, npm, docker, eksctl in /opt on build-server
• Step 3 - Master - Slave Configuration
• Step 4 - Jfrog Account creation. Generate a token in Jfrog and configure the token in Jenkins GUI
• Step 5 - Install the nodejs plugin, artifactory plugin, Docker pipeline plugin in Jenkins GUI
• Step 6 - Configure nodejs in Global tool Configuration
• Step 7 - Create a dedicated user to use for a Docker login in Jfrog
• Step 8 - Create a Continuous Integration pipeline
• Step 9 - Deployment in Kubernetes
• Step 10 - Access Node.Js Application

• Become root user

sudo su - 

yum install git -y

• Note - When your installing 3rd party softwares. It is recommended to use opt directory

cd /opt 

amazon-linux-extras install java-openjdk11 -y

• Check Java version

java -version

wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo

rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

yum install jenkins -y

service jenkins start

• Browse - giveurjenkinsserverip:8080

cat /var/lib/jenkins/secrets/initialAdminPassword

• Select (install suggested plugins)

• Note: I have given random. Give according to your convinience.
• username: admin
• password: password
• confirm password: password
• Full name: Pavan
• Email-address: admin@gmail.com
• Click (save & continue)
• Click (save & finish)
• Click (start using jenkins)

• Become root user

sudo su - 

yum install git -y

• Note - When your installing 3rd party softwares. It is recommended to use opt directory

cd /opt 

amazon-linux-extras install java-openjdk11 -y

• Check Java version

java -version

• Reference - Install npm - https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-up-node-on-ec2-instance.html

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

. ~/.nvm/nvm.sh

nvm install 16

• To check version

node -e "console.log('Running Node.js ' + process.version)"

yum install docker -y

service docker start

service docker status

• To confirm weather docker service is running or not

docker info  

• Docker should have permissions to /var/run/docker.sock

chmod 777 /var/run/docker.sock

cd ~

exit

• Install - AWS CLI

aws --version

• By default you can able to see aws cli as we r using amazon linux aws-cli/2.10.0 Python/3.9.11 Linux/5.10.165-143.735.amzn2.x86_64 exe/x86_64.amzn.2 prompt/off

• Set Up kubectl - https://docs.aws.amazon.com/eks/latest/userguide/install-kubectl.html

curl -O https://s3.us-west-2.amazonaws.com/amazon-eks/1.23.16/2023-01-30/bin/linux/amd64/kubectl

Execution Permissions

chmod +x ./kubectl

Move kubectl to Usr local bin

sudo mv ./kubectl /usr/local/bin

Check the kubectl version

kubectl version --short --client

• Set Up eksctl - https://docs.aws.amazon.com/eks/latest/userguide/eksctl.html

curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp

sudo mv /tmp/eksctl /usr/local/bin
