The Very first step is to install Docker in your EC2 instance
sudo yum update
sudo yum install docker
Now, will create a folder for our project
mkdir nodeApp
cd nodeApp
nano Dockerfile
Add the below given code in Dockerfile
FROM node
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 3000
CMD ["node", "app.js"]
To build our Docker image, run the following command:
docker build -t username/nodeApp:v1 .
Now, for all the file and folders you can go through the repo and get it into your repo or you can create it into your system and push into the repo using the git commands
git remote add origin https://github.com/username/repository_name
In order to integrate your Github repository to your Jenkins Project, you need to set up a web-hook. Web-hooks can only work over a public IP, therefore, we require a reverse proxy to create a secure tunnel from a public endpoint (Github) to our locally running web service (Jenkins).
for configuring the Jenkins into your system use following commands
sudo yum update –y
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
sudo yum upgrade
sudo amazon-linux-extras install java-openjdk11 -y
sudo yum install jenkins -y
sudo systemctl enable jenkins
sudo systemctl start jenkins
sudo systemctl status jenkins
After running all the command Now connect to Jenkins webUI with public IP forwarded by :8080 port. (http://<your_server_public_DNS>:8080)
Install following Plugins while installing the Jenkins
Blue Ocean Credentials Plugin Docker Plugin Github Plugin NodeJS Plugin Oracle Java SE Development Kit Installer Plugin Pipeline Plugin Timestamper
Navigate back to the home page and create a new build by clicking on New Item. Enter your project name and select Freestyle project and click OK:
In the Build Triggers section, select Github hook trigger for GITScm polling.
NOTE : If the NodeJS plugin has not been activated, Save and Apply changes, then navigate to Manage Jenkins > Global Tool Configuration and look for the NodeJS heading. Install whatever version of NodeJS you require and click save
Navigate back to our freestyle job and in the Build section, click Add build step > Execute Shell and type in the following commands:
npm install
npm test
Before we create a new build, we require two elements:
Name of the Docker Repository Dockerhub credentials on Jenkins Open up a new tab and login to your Dockerhub account. Click on Create Repository, enter a name and click Create. This will indicate to Jenkins where the Docker Image will be pushed.
Once saved, navigate back to the home page and click on New Item.
Enter your project name and select Pipeline and click OK:
In the General Section, enter the same project url as the previous Jenkins build we configured earlier.
In the Pipeline section, we will be creating a script to tell Jenkins to create a Docker Image and deploy onto Dockerhub. The pipeline script is based on the Apache Groovy programming language.
Click on Save and Apply
We can now check our Dockerhub to see if our image has been pushed automatically to the repository.

Prerequisite - Having Nginx Installed using - yum install nginx
Installing the certbot for the SSL using Letsencrypt
sudo apt install certbot python3-certbot-nginx sudo vim /etc/nginx/nginx.conf
in the nginx.conf file , add your omain in the server name , Here, I have taken the domain from Freenom.com and configured it using the Hosted zone in Route 53 using the nameservers
Find the existing server_name line. It should look like this:
If it doesn’t, update it to match. Then save the file, quit your editor, and verify the syntax of your configuration edits:
nginx -t
sudo systemctl reload nginx
nginx.conf file
proxy setup to redirect it to the nginx port 80
sudo certbot --nginx -d django1.tk -d www.django1.tk
