Jenkins project - 2

• Jenkins project - 2 (deploy node js app on server)

Step 1 : In this step we have to create aws ec2 instance.

Step 2 : Install Jenkins.

Pre-Requisites:

• Java (JDK)

Run the below commands to install Java and Jenkins

Install Java

 sudo apt update
sudo apt install openjdk-11-jre

Verify Java is Installed

java -version

Now, you can proceed with installing Jenkins

curl -fsSL https://pkg.jenkins.io/debian/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 binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins

Note: By default, Jenkins will not be accessible to the external world due to the inbound traffic restriction by AWS. Open port 8080 in the inbound traffic rules as show below.

• EC2 > Instances > Click on

• In the bottom tabs -> Click on Security

• Security groups

• Add inbound traffic rules as shown in the image (you can just allow TCP 8080 as well, in my case, I allowed All traffic).

Step 3 : Login to Jenkins using the below URL:

http://:8080 [You can get the ec2-instance-public-ip-address from your AWS EC2 console page]

Note: If you are not interested in allowing All Traffic to your EC2 instance 1. Delete the inbound traffic rule for your instance 2. Edit the inbound traffic rule to only allow custom TCP port 8080

After you login to Jenkins, - Run the command to copy the Jenkins Admin Password - sudo cat /var/lib/jenkins/secrets/initialAdminPassword - Enter the Administrator password.

sudo apt install docker.io

Step 9 : Grant Jenkins user and Ubuntu user permission to docker deamon.

sudo usermod -aG docker jenkins
sudo reboot

Step 10 : Know build again ....

Step 11 :

Step 12 : You need to add port 8001 into your aws security group.

Step 13 : finally your to do app is running on port 8001:

<your public ip address>:8001

Step 14 : You need to install docker-compose on your server.

 sudo apt install docker-compose

Note : Before building docker compose container you need to stop previous conainer using below command .

 sudo docker ps
 sudo docker kill <id>

click on Build again ....

Note : How to run docker container again with docker-compose

 docker-compose up -d --no-deps --build web

Project : In this project we deploy node to to app

Step 15 : You need to add custom tcp port 8080 and source anywhere.
