3. Workflow
Developer pushes code → GitHub → Webhook → Jenkins → Deployment


4. Jenkins Job Configuration

      Job Type: Pipeline
      Source: GitHub repository
      Credentials: GitHub token
      Trigger: GitHub webhook
      Build Step: Execute shell script


4. Deployment Script
Script present in Jenkins Web UI

Dashboard>oxypc>Configuration inside build steps

TARGET_DIR="/var/www/html/deshwal"
WORKSPACE_DIR="/var/lib/jenkins/workspace/deshwal_dev"

mkdir -p $TARGET_DIR
# Ensure permissions before deployment
sudo chown -R jenkins:www-data $TARGET_DIR
sudo chmod -R 775 $TARGET_DIR

# Deploy code
cp -r $WORKSPACE_DIR/ $TARGET_DIR/

# Fix permissions after deployment sudo chown -R jenkins:www-data
$TARGET_DIR sudo chmod -R 775 $TARGET_DIR


5. Backup Script
Script present in /opt/Deshwal_pipeline_code_backup.sh
#!/bin/bash

TARGET_DIR="/var/www/html/deshwal"
BACKUP_DIR="/opt/Deshwal_pipeline_code_backup"

TIMESTAMP=$(date +%Y-%m-%d_%H-%M-%S)

sudo mkdir -p $BACKUP_DIR

if   [ -d "$TARGET_DIR" ]; then
      sudo cp -r $TARGET_DIR $BACKUP_DIR/deshwal_backup_$TIMESTAMP
fi

6. Retention Policy

Only last 5 backups are retained.

Retention Script
KEEP=5

cd /opt/Deshwal_pipeline_code_backup

ls -1dt deshwal_backup_* | tail -n +$((KEEP+1)) | while read
backup do
     sudo rm -rf "$backup"
done
