TodaySphere Node.js App which has completely automated deployment using Jenkins, AWS EC2, Docker and GitHub CI/CD. This app accepts location as an input from the user and based on that it shows the current weather, news for that location/region, an activity of the day which the user can perform and NASA's Astronomy Picture of the Day. A one-stop solution to start a good day! 😃

For the Devops part of this project, I created an AWS EC2 instance, installed Jenkins on the server, then integrated Jenkins with this GitHub repository containing Node.js app code. Next, using Docker, I dockerized the Node.js app and automated this process on Jenkins. Finally automated the whole process using GitHub Webhooks.

App Name: Today + Atmosphere(around you) - TodaySphere 😉

To get started with the project, follow these steps:

• AWS account
• GitHub account

Note:

• Make sure to enable port 8080 inbound traffic while creating the EC2 instance

• (with default settings) Login as "ubuntu" using putty with the .ppk file

• Inside the EC2 instance (choose OS as Ubuntu)

sudo apt update

• Installing Java inside EC2 instance

sudo apt install openjdk-11-jre

java -version

• Installing Jenkins on EC2 instance

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key |sudo gpg --dearmor -o /usr/share/keyrings/jenkins.gpg

sudo sh -c 'echo deb [signed-by=/usr/share/keyrings/jenkins.gpg] http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee \
  /usr/share/keyrings/jenkins-keyring.asc > /dev/null
  
echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null

sudo apt update

sudo apt install jenkins

sudo systemctl start jenkins.service

sudo systemctl status jenkins

sudo cat /var/lib/jenkins/secrets/initialAdminPassword

• After setting up Jenkins, use the following commands to integrate it with GitHub

ssh-keygen

cat id_rsa.pub

cat id_rsa

• Running the Node.js app on EC2 instance

cd /var/lib/jenkins/workspace/todaysphere-app

sudo apt install nodejs

sudo apt install npm

sudo npm install

node app.js

• Installing Docker and Containerizing the Node.js app

sudo apt install docker.io

sudo chmod 777 /var/run/docker.sock

sudo docker build . -t todaysphere_app

sudo docker run -d --name todaysphereapp -p 3000:3000 todaysphere_app:latest

• Jenkins Build step (execute shell)

docker build . -t todaysphere_app

docker container rm -f todaysphereapp

docker run -d --name todaysphereapp -p 3000:3000 todaysphere_app:latest

• Optional - To open access to ports/firewall modification (incase 8080 port does not open)

sudo ufw allow OpenSSH

sudo ufw enable

sudo ufw allow 8080

sudo ufw status
