Day80(DevOps)-Project -1

Project Description

The project aims to automate the building, testing, and deployment process of a web application using Jenkins and GitHub. The Jenkins pipeline will be triggered automatically by GitHub webhook integration when changes are made to the code repository. The pipeline will include stages such as building, testing, and deploying the application, with notifications and alerts for failed builds or deployments.

Steps:

Step1:Launch an EC2 instance with below Jenkins/docker installation script.

#!/bin/bash
    sudo apt-get update
    sudo apt install default-jre
    sudo apt install default-jdk
    curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee \
    /usr/share/keyrings/jenkins-keyring.asc > /dev/null
    sudo sh -c '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 -y
    sudo systemctl start jenkins
    sudo systemctl enable jenkins
    sudo apt-get install docker.io -y
    sudo usermod -aG docker jenkins
    sudo systemctl start docker
    sudo systemctl enable docker

Check status of jenkins/docker if running or not.

Once done with installations open port 8080 security group

Step2:Try to access public IP 3.83.153.244:8080

Unlock Jenkins by below key

Create credentials for 1st time user

Good to go with Jenkins now!

Step3:generate keys by ssh-keygen

This will generate public and private keys in the machine.

Id_rsa – Private Key.

Id_rsa.pub – Public Key.

Step4:Navigate to manage jenkins and under available plugins search for github integration as we need this plugin for the integration with github(our code is in github)

Install without restart

Check download progress

Step5:Now move back to our problem statement for project

Select new item like below

Select project type:Freestyle project

Provide project description:The project aims to automate the building, testing, and deployment process of a web application using Jenkins and GitHub. The Jenkins pipeline will be triggered automatically by GitHub webhook integration when changes are made to the code repository. The pipeline will include stages such as building, testing, and deploying the application, with notifications and alerts for failed builds or deployments.

Step6:Code is available on github copy code url and put under project url

Step7:Build step:

Docker build: docker build -t django-notes-app (-t--tag)

Docker run: docker run -d -p 8000:8000 django-notes-app (-d=detach modei.e.runs in background,-p=port expose,8000=port number,Django-notes-app=image of the name)

Step8:Successful Build...!!!

Open port number 8000 under the security group and access public ip

Access your public IP now:54:227:159:62:8000

Finally Here is the output:

Step9:Now lets move to the CICD part

This is to autotrigger the builds if any changes in code we do not have to trigger manually.

cd .ssh -->>ssh-keygen-->>put this key ubuntu@ip-172-31-26-35:~/.ssh$ cat id_rsa.pub

Setting-->>and generate Personal access token this we can provide in jenkins under secret text

Step10:Add this secret key in jenkins under secret

Select this option to trigger the build after code change in git it will reflect

Step11:Navigate to setting-->>webhook-->>54.227.159.62:8080/github-webhook

Webhooks can be triggered whenever specific events occur on GitHub. For example, you can configure a webhook to trigger whenever: Code is pushed to a repository.
