devops-cli-tool

A Python Typer-based CLI with small DevOps utilities for health snapshots, port inspection, Docker cleanup, and generating a basic nginx reverse proxy config.

Key features

• System health command using psutil
• Listening port inspection via ss
• Dry-run Docker prune helper
• Nginx config file generator

Project structure

• devops_tool.py — CLI commands
• requirements.txt — Runtime dependencies

Requirements

• Python 3.9+
• ss for the ports command
• Docker CLI for docker-clean
• Optional nginx knowledge to validate generated config

Setup

git clone https://github.com/biprajit007/devops-cli-tool.git
cd devops-cli-tool
python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt

Usage

Health snapshot

python3 devops_tool.py health

Inspect a port

python3 devops_tool.py ports --port 8080

Dry-run Docker cleanup

python3 devops_tool.py docker-clean --dry-run

Generate nginx config

python3 devops_tool.py nginx-config example.com 127.0.0.1:9000 --out ./nginx.conf

Safety notes

• Keep docker-clean in dry-run mode unless you explicitly want to remove unused Docker resources.
• Generated nginx config is a starter template and should be reviewed before deployment.

Limitations / next improvements

• Commands are local-only
• No Windows-specific support
• Docker cleanup has no preview beyond printing the command
