+## Complete Step-by-Step Jenkins CICD with GitHub Integration:
+
+
+link: https://medium.com/@mudasirhaji/complete-step-by-step-jenkins-cicd-with-github-integration-aae3961b6e33
+
+## Prerequties: AWS ec2 instance,Docker,Github,Jenkins
+
+1)create personal access token
+2)Jenkins and github integration
+3)CI/CD Pipeline
+4)create ubuntu 20.04 ec2 instance with the name (Jenkins-master)/t2.micro/sg-SSH/HTTP/HTTPS/Custom TCP:8080/custom TCP:8000-anywhere/8gb storage.
+
+## create personal access token:
+
+-go to the github settings - devloper setting - personal access token - Tokens(classic) - click on generate new token
+  
+New token : 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  
+
+## First install Jenkins:
+
+-sudo apt-get update
+-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 fontconfig openjdk-11-jre -y
+-java -version
+-sudo apt-get install jenkins -y
+-sudo systemctl enable jenkins
+-sudo systemctl start jenkins
+-sudo systemctl status jenkins
+-go to browser and paste public ip with 8080 port
+-sudo cat /var/lib/jenkins/secrets/initialAdminPassword
+
+## Install docker:
+
+-sudo apt update
+-sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
+-curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
+-echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+-sudo apt update
+-sudo apt install docker-ce -y
+-sudo systemctl start docker
+-sudo systemctl enable docker
+-docker --version
+-sudo usermod -aG docker $USER
+
+## Create Public & Private key
+-ssh-keygen     - enter - enter -enter - created private key
+-cd .ssh
+-cat id_rsa   (private key)
+-cat id_rsa.pub  (public key) if its not working
+-cat /root/.ssh/id_rsa.pub  (public key)
+
+## GITHUB settings:
+now go to github account in settings - SSH and GPG key - New SSH key - Title -Jenkins-project- paste public key in blank field -Add SSH key - enter authentication token which is received on mobile and verify (now a days not received auth token on mobile )
+
+-go to Jenkins dashboard -new item - name(todo-node-app)-freestyle project
+-Genral - descripstion-this is node js todo app - select SCM -git -paste url of git repo - Add credentials - Domain - default - Kind - SSH username with private key - Id -github-jenkins- description - this is for jenkins and github intigration - username - paste instance username(ubuntu)- private key - click enter directly - paste private key - Add - select again credentials option - branch to build - */main -repository browser(auto) - apply and save
+
+now build the project.. you will get the successed output
+
+check on terminal using below cmd you will see jenkins has been integrated with github
+
+-cd /var/lib/jenkins/workspace/todo-node-app
+-sudo apt install nodejs -y
+-sudo apt install npm -y     (node package manager)
+-sudo npm install    
+
+sudo npm audit fix     (if error occurs use this cmd to fix the issue)
+-sudo npm audit fix --force (to address all isssue)
+-sudo npm audit     (for details) 
+-node app.js        (you will see the app is running on 8000)
+
+-go to browser and paste public IP with 8000 port, you will get the output
+
+
+Now we are going to deploy our app using docker container for that we need to install docker first which is we have already installed;
+
+## Create Dockerfile under same path - 
+
+-cd /var/lib/jenkins/workspace/todo-node-app
+
+FROM node:12.2.0-alpine
+WORKDIR app
+COPY . .
+RUN npm install
+EXPOSE 8000
+CMD ["node", "app.js"]
+
+-sudo chmod 777 /var/run/docker.sock    -give the permission to docker.sock
+-docker build . -t todo-node-app1    (build the image)
+-docker images
+-docker run -d --name node-todo-new -p 8000:8000 todo-node-app1    (build the container from the same Image)
+-docker ps
+
+when we add build steps you will get error for permission:use below cmd for resolve error
+
+-sudo chmod 777 /var/lib/jenkins/workspace/todo-node-app
+-sudo usermod -a -G docker jenkins
+
+## Step 7: Configure Web-hook:
+
+first kill the running container using below cmd:
+
+-docker kill “container-id” command.
+
+- go to github repo setting > webhooks > payload url <http://54.221.123.31:8080/github-webhook/ > content type (application/json) > save
+
+go to the jenkins dashboard:
+
+let’s install the GitHub Integration plugin in Jenkins, to integrate it with Webhooks:
+
+Go to Manage Jenkins > Manage Plugins > Available Plugins > Search for “GitHub Integration” > Select Install Without Restart
+
+After adding the plugin we need to add the webhook in our GitHub repo:
+
+Now go to Jenkins > Dashboard > Job > Configure > Build Triggers > Select “GitHub hook trigger for GITScm polling” > Save
+
+Now change the code in GitHub a bit to see if the integration works.
+
+-you will see job will run automatically.
