DevOps Projects

A collection of shell scripting, Docker, and Linux automation projects focused on system administration, containerization, and security monitoring.

Shell Scripting Projects

Backs up directories with compression, timestamping, automatic rotation (deletes backups older than 7 days), and success/failure logging.

Tools: tar, find, date

Parses Nginx/Apache access logs to generate reports on traffic patterns — top IPs, status code breakdown, top requested paths, and suspicious scan detection.

Tools: awk, grep, sort, uniq

Detects brute-force SSH attacks by parsing auth.log for failed login attempts and flagging IPs that exceed a suspicious threshold.

Tools: grep, awk, sort, uniq

Docker Architecture Projects

A progression of the same task tracker app built across three architectures, demonstrating containerization, networking, and separation of concerns.

Frontend, backend, and database (SQLite) all running in a single container.

App (Flask) and database (PostgreSQL) split into separate containers, communicating over a custom Docker network.

Nginx (reverse proxy) + Flask (application) + PostgreSQL (database), each in its own container. Only Nginx is exposed to the host — the app and database are internal-only.

Tools: Docker, Docker Compose, Flask, PostgreSQL, Nginx

Skills Demonstrated

  • Bash scripting and automation
  • Log parsing and text processing (awk, grep, sed)
  • Linux system administration
  • Basic security monitoring / intrusion detection
  • Docker containerization and multi-container orchestration
  • Container networking (custom bridge networks, service discovery)
  • Reverse proxy configuration (Nginx)
  • Environment-based configuration and data persistence (volumes)
  • Git version control
