DevOps-Project-4

Deploy Website on Docker with code analysis tool SonarQube using ec2 instance & Jenkins

Project GitHub Link :-

https://github.com/rutikdevops/DevOps-Project-4

Project Overview :-

• In this project I created a CICD Pipeline. In which push the code in GitHub and from the github I will push the code to Jenkins and After pulling the code from GitHub I will Test the code from SonarQube which is static code analysis tool In which we can solve bugs & vulnarities also we can add the rules regarding scanning. After scanning the code If code pass I deployed code on Docker

Project Steps :-

• Create 3 ec2 instance :

1. Jenkins-Server : AWS Linux-2, t2 micro
2. Docker-Server : AWS Linux-2, t2 micro
3. SonarQube-Server : AWS Linux-2, t2 medium

1. Install and Configure the Jenkins :-

ec2-user
sudo su
yum update -y
hostnamectl set-hostname jenkins
bash

• Java installation on Jenkins server:-

yum install java* -y
java --version
alternatives --config java              ## Using this command you can choose any version of Java
                                        // select java 11 version

• Jenkins installation on Jenkins server:-

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-2023.key
yum install jenkins -y
systemctl enable jenkins.service
systemctl start jenkins.service
systemctl status jenkins.service

• Copy public ip of jenkins server and paste it in new tab with port no.8080

• copy this path and paste in terminal with “cat” command

cat /var/lib/jenkins/secrets/initialAdminPassword

• Now copy & paste this passwd in jenkins. so, jenkins is ready.

2. Run the code in jenkins:

• Jenkins-> New Item-> Freestyle Project-> Source Code Management-> Git

• Connect github to jenkins through webhook

• Build Now in Jenkins

3. Run sonarqube

ec2-user
sudo su
yum update -y
hostnamectl set-hostname sonarqube
bash

• Java installation on Jenkins server:-

yum install java* -y
java --version
alternatives --config java              ## Using this command you can choose any version of Java
                                        // select java 11 version

cd /opt
wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-8.9.10.61524.zip  #(chrome-downloadsonarqube-latestversion-rightclick-copypaste)
unzip sonarqube-8.9.10.61524.zip
cd sonarqube-8.9.10.61524
cd bin
cd linux-x86-64
./sonar.sh start
./sonar.sh status    (in that sonarqube is not running)
cd ../..
cd logs
useradd sonaradmin
chown -R sonaradmin:sonaradmin /opt/sonarqube-8.9.10.61524
pwd
cd ..
su - sonaradmin
cd /opt/sonarqube-8.9.10.61524/
cd bin
cd linux-x86-64
./sonar.sh start
./sonar.sh status
netstat -tulpn        #(command for check port)
                      #(paste public ip with :9000)
                      #(securitygroup-inboundrule-all traffic, anywhere)
                      #(username passwd bydefault is admin)

4. Connect to terminal and install docker :-

sudo su - 
yum install docker -y
systemctl start docker
systemctl enable docker
systemctl status docker
useradd dockeradmin
passwd dockeradmin
usermod -aG docker dockeradmin
vim /etc/ssh/sshd_config
 ( PasswordAuthentication yes )
systemctl restart sshd

• Lets Integrate Docker with Jenkins
• Jenkins -> Manage Jenkins -> Plugins -> Available -> Search for Publish Over SSH -> Install
• Lets configure Docker in Jenkins
• Jenkins -> Manage Jenkins -> System -> Publish Over SSH -> SSH Servers -> Add -> Give Name -> Hostname : -> Username : dockeradmin -> advanced -> enable password based authentication -> password : <password of dockeradmin -> test configuration -> Apply -> Save
• Successfully instegrated docker with jenkins.
• Now goto docker server

cd /opt
mkdir docker
cd docker
chown -R dockeradmin:dockeradmin /opt/docker
vim Dockerfile
FROM tomcat:latest
RUN cp -R /usr/local/tomcat/webapps.dist/* /usr/local/tomcat/webapps
COPY ./*.war /usr/local/tomcat/webapps
 
chmod 777 /var/run/docker.sock

• Now Create a Jenkins job to pull the code from Github , build with help of Maven and copy the Artifacts to Dockerhost.
• Jenkins -> Dashboard ->New project-> DevOps-Project-4-> maven project-> Source Code Management-> Post-build Actions -> select Send build artifacts over SSH -> SSH Server -> Name : give name of Added SSH Server -> Source file: webapp/target/*.war -> Remove prefix : webapp/target -> Remote directory : //opt//docker -> Exec command : enter the below commands

cd /opt/docker;
docker build -t regapp:v1 .;
docker stop registerapp;
docker rm registerapp;
docker run -d --name registerapp -p 8081:8080 regapp:v1

• Apply -> Save

Output :-

Final Output :-

• In this section, we have successfully deployed the application to the Docker server and enabled CI/CD. If any changes occur in the source code, they will be automatically built and deployed to the server.
