hop3-cli

Command-line interface for interacting with Hop3 servers.

Overview

hop3-cli is a thin client that communicates with hop3-server via JSON-RPC over HTTP or SSH tunneling. It provides a familiar Heroku-like CLI experience for deploying and managing applications.

Features

• Application management - Deploy, start, stop, restart, and scale applications
• Environment variables - Securely manage app configuration
• Log streaming - View real-time application logs
• Addon management - Provision and manage backing services (PostgreSQL, Redis, MySQL)
• SSH tunneling - Secure communication with remote servers
• Multiple output formats - Human-readable, JSON, or quiet mode
