Module remote_actions 

Remote actions module (Level 3 of Three-Level Architecture)

This module provides the lowest-level operations in the three-level architecture, containing leaf-level actions that directly interact with remote systems via SSH. These actions are the building blocks used by steps (Level 2) and commands (Level 1).

Execution Context: Inside VM via SSH

All remote actions in this module execute commands INSIDE the VM via SSH. For external validation (E2E testing from outside the VM), see external_validators/.

Distinction:

• remote_actions (this module): Execute commands inside VM via SSH
• external_validators: Validate services from outside VM via HTTP

Available Remote Actions

• validators::cloud_init - Cloud-init status checking and validation
• validators::docker - Docker installation and service management
• validators::docker_compose - Docker Compose installation and validation

Architecture Pattern

Remote actions follow a consistent pattern:

• Take SSH connection and required parameters
• Execute specific remote operations via SSH
• Provide structured error handling with action context
• Return typed results for use by higher-level components

These actions are designed to be atomic, testable, and reusable across different deployment scenarios.
