Linux & Terminal Commands Project: Beginner to Advanced for DevOps
Project Title: DevOps Linux Mastery
Objective:
Master Linux and terminal commands from beginner to advanced levels while building a DevOps-focused project. By the end, you’ll have hands-on experience with Linux, scripting, automation, and integration with DevOps tools like Docker and Kubernetes.
Project Structure:
DevOps-Linux-Project/ ├── scripts/ # Bash scripts for automation ├── logs/ # Log files for the project ├── backups/ # Backup files ├── configs/ # Configuration files └── README.md # Documentation
Phase 1: Basics of Linux
#1. Setup
Example: Install Ubuntu
Install Ubuntu (or any Linux distribution) on a virtual machine or dual boot.
Familiarize yourself with the terminal.
#2. Basic Commands
Example: Create Project Structure
Learn and practice: ls, cd, pwd, mkdir, touch, rm, cp, mv.
Create the project directory structure:
mkdir -p DevOps-Linux-Project/{scripts,logs,backups,configs}
#3. File Manipulation
Example: Modify Permissions
Use editors like nano and vi to create and edit files.
Practice file permissions:
chmod +x scripts/* chown $USER:$USER logs/
#4. Practice Script
Example: Automate Directory Creation
Write a script to automate the creation of the project structure:
#!/bin/bash mkdir -p DevOps-Linux-Project/{scripts,logs,backups,configs} touch DevOps-Linux-Project/{scripts/script1.sh,logs/app.log,configs/app.conf} echo "Project structure created!"
#Phase 2: Intermediate Linux Skills
#1. Process Management
Example: List Running Processes
Learn ps, top, kill, jobs, bg, fg.
#2. Networking Commands
Example: Check Connectivity
Practice ping, curl, wget, ifconfig.
#3. Archiving and Compression
Example: Compress Logs
Use tar, gzip, gunzip, zip, unzip.
#4. Task Automation
Example: Schedule Backups
Schedule a daily backup of the logs/ directory using cron:
crontab -e
Add the following line:
0 2 * * * tar -czf ~/DevOps-Linux-Project/backups/logs_backup_$(date +%F).tar.gz ~/DevOps-Linux-Project/logs/
Phase 3: Advanced Linux Skills
#1. Advanced Scripting
Example: Monitor Disk Usage
Write a script to monitor disk usage and send an alert if it exceeds a threshold:
#!/bin/bash THRESHOLD=80 USAGE=$(df / | grep / | awk '{print $5}' | sed 's/%//g') if [ "$USAGE" -gt "$THRESHOLD" ]; then echo "Disk usage is above $THRESHOLD%. Current usage: $USAGE%" fi
#2. User and Group Management
Example: Add a User
Add/remove users and groups.
Manage permissions and ownership.
#3. Log Analysis
Example: Search Logs
Use cat, grep, awk, tail, and head to analyze logs in logs/app.log.
#4. Version Control
Example: Initialize Git Repository
Initialize a Git repository and commit the project files:
git init git add . git commit -m "Initial commit"
#Phase 4: DevOps Integration
#1. Docker Integration
Example: Create a Dockerfile
Create a Dockerfile to containerize a Bash script:
FROM ubuntu:latest COPY scripts/monitor.sh /usr/local/bin/monitor.sh RUN chmod +x /usr/local/bin/monitor.sh CMD ["/usr/local/bin/monitor.sh"]
#2. Ansible Playbooks
Example: Automate Script Deployment
Write a playbook to deploy the scripts and configure cron jobs.
#3. Kubernetes Deployment
Example: Deploy as CronJob
Deploy the Dockerized script as a Kubernetes CronJob.
#Final Phase: Documentation and Submission
#1. Documentation
Example: Write README
Write a detailed README.md file explaining:
Project overview
Commands used
Scripts and their purpose
Integration with DevOps tools
#2. Project Submission
Example: Push to GitHub
Push the project to your GitHub repository:
git remote add origin <repository_url> git push -u origin main
Outcome:
By completing this project, you will:
Gain proficiency in Linux commands.
Develop automation scripts.
Integrate Linux skills with DevOps tools like Docker, Ansible, and Kubernetes.
Build a portfolio-ready project showcasing your Linux and DevOps expertise.
