TABLE OF CONTENTS Launch Instances Install Jenkins Creating a Pipeline in Jenkins Server Adding a Webhooks Starting a SonarQube Server Installing Docker Password-based Server Connectivity Building the Image and running the container
I have created 3 t2.medium instances
Update the system
sudo apt update clear
Now we have to install java first before installing Jenkins
sudo apt install openjdk-11-jre -y
Now we have to paste the Jenkins commands
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-get update sudo apt-get install jenkins
Now we have to allow port 8080 in the Jenkins server security group inbound settings
Now use the public api of instance with port 8080 to view the Jenkins server
Copy the command which was highlighted in the above picture and use the command
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
It will show the output a password for the Jenkins server
Copy the password and paste it to the Jenkins server
Click on -> Install suggested plugins
You can set admin credentials
Jenkins Installation done
In this, I have selected the Freestyle projectIn the source code management, I have selected the Git option
Also select branch of your git
Now open the settings of your Git Repository, select webhooks
Click to Add Webhook, that time it will ask you to enter your password,
once you enter your password, you're able to add Webhooks.
Click to Add Webhook
Now in Build Triggers, select the GitHub hook trigger for GITScm polling
(because this function can trigger the pipeline automatically whenever we make changes to the repository.
Click to save.
Without Webhook I have clicked to Build now and it is working perfectly fine
Now time to verify Webhooks, I have clicked on the workspace in Jenkins,
and here text.txt file is not present which I am going to create to test the Webhook
I have visited the Git Repository and created a new file by the name of test.txt
I committed the file
Now I am back to the Jenkins server to check #2 build auto trigger and it is working fine.
Now test.txt file is showing in the workspace
Start the Sonarqube Instancesudo apt update clear
We need to install Java on the server but 17 version earlier we were using 11 version
sudo apt install openjdk-17-jre -y
Search for the SonarQube website and download the community for the free version
SonarQube Download Copy the link and paste it to the terminal of the SonarQube Instance
sudo adduser sonarqube
Use the command below with wget
wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-9.4.0.54424.zip
sudo apt install unzip unzip * ls
Now the unzipped file is showing
cd sonarqube-9.4.0.54424 ls
Go to the bin folder
cd bin cd linux-x86-64 ls
Now start the sonar server by using the command
./sonar.sh start
And also we need to port 9000 in the inbound setting of the security group
Now it's time to check the URL http://54.88.67.190:9000/
Update the password
After updating the password we can access the Sonarqube
Now I have selected the project type Manually
After this, I have selected the CI platform, Jenkins
Selected the DevOps platform GitHub
You can just simply select the options Configure Analysis
Also, click on Continue here
From here I have selected the Others
Copy the ProjectKey for now you can keep this Key in your notepad
sonar.projectKey=Sample-website
Finish the tutorial
Now click to settings, we need to create token
Now I have created the Token and copy the token for now you can keep this token in your notepad
Now back to Jenkins, Manage Jenkins and Install the plugin
Install one more plugin
Restart Jenkins after installation of plugins
Now Go to the Global Tool Configuration
After saving it, Click to Manage Jenkins again and click on Configure System
Configure System
Save
After Saving, Click Configure of the Pipeline in Jenkins
Ignore everything just paste the key here rest default and saved it
Now back to Manage Jenkins, select Configure System again
Now we have to add token here
Select Token after adding and click on save
Now go back to Pipeline to verify whether it's working or not, it's absolutely working fine
Now going to check SonarQube, it's perfectly working fine
Once our code is passed now I am going to deploy it on Docker
Started InstanceInstall Docker
Update the apt package index and install packages to allow apt to use a repository over HTTPS:
sudo apt-get update sudo apt-get install \ ca-certificates \ curl \ gnupg
Add Docker’s official GPG key:
sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg
Use the following command to set up the repository:
echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Update the apt package index:
sudo apt update
To install the latest version, run:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-pluginNow I am going to make connection between Jenkins server and Docker server
After running all the commands go back to the Jenkins server
sudo su jenkins
Open Docker server
sudo su nano /etc/ssh/sshd_config
And change the Password Authentication to Yes
systemctl restart sshd
Back to Jenkins Server
Now you can see it's asking for the password earlier it's showing permission denied
Now we have to change the password of the Docker Ubuntu user
Back to Docker Server
passwd ubuntu
Back to Jenkins Server
ssh [email protected]
Now I am going to generate SSH Key in Jenkins Server
After generating keygen I entered the command
ssh-copy-id [email protected]
After running the command enter the password
ssh [email protected]
Back to Jenkins again
Now we have to add a server list
Now go to Pipeline
Configure
Post-build action
Add build step
Now I am gonna build the pipeline to verify whether it's working or not
And it seems to be working
Open Docker Server, as we can our file got created here
Open the Git Repository now
See Auto trigger started
Now returned to Pipeline, configure
Created a folder in the Docker server
Clicked to execute shell and fill the details, here I entered docker server IP and folder which is website
We have got the success message here and let us check our docker server
All the files copied to the Docker server
sudo usermod -aG docker ubuntu newgrp docker
After giving the permission we are able to use the docker without sudo
docker ps
Now back to Jenkins
Time to check our docker container got created or not
It got created but we have to add port 8085 in the inbound setting of the security group
Now time to check the public URL of the docker Instance http://54.227.42.50:8085/ (our code is successfully deployed on docker container)
