v2.1.0

v2.1.0 – Modular Rewrite & SSH Security Features

This release introduces a full modular rewrite of the deployment logic and adds several SSH security-related options, improving flexibility, security and maintainability across Compose and Stack deployments.

What’s New

• Modular Shell Script Structure
  The deployment logic has been split into separate, focused scripts. This makes the action easier to understand, maintain and build upon.

• Passphrase Support for SSH Keys
  Users can now provide an ssh_key_passphrase to support encrypted private keys using ssh-agent.

• SSH Host Key Verification
  The action now supports:

  • ssh_known_hosts: full OpenSSH-compatible known_hosts content
  • fingerprint: a single-line public key for quick verification
  • If neither is provided, the host key is fetched via ssh-keyscan with a security warning

• SSH Timeout Configuration
  A timeout input has been added to limit SSH connection attempts, helping prevent hanging builds in CI environments.

• Conditional Compose Image Pulling
  Users can now set compose_pull to false to skip docker-compose pull, useful for offline or pre-pulled deployments.

Improvements

• All deployment logic has been restructured for clarity and reusability
• Docker Compose and Stack flows are now handled by separate scripts with correct environment and path handling
• More accurate and consistent logging throughout the deploy process

Stability and Maintenance

• Improved SSH connection handling with ConnectTimeout, ServerAliveInterval and ServerAliveCountMax
• All changes are backwards compatible — no breaking changes introduced

Tags

• v2.1.0: Latest release (recommended)
• v2: Major version tag for stable workflows
