Module Mountain 

Mountain Client Module

This module provides the gRPC client implementation for Air to communicate with Mountain. Air acts as a client connecting to Mountain’s gRPC server for requesting status, health checks, and configuration operations.

Architecture

Air (Background Daemon) ──► MountainClient ──► gRPC ──► Mountain (Main App)

Features

• Connection Management: Establish and maintain gRPC connections to Mountain
• Health Monitoring: Check Mountain’s health status
• Status Queries: Query Mountain’s operational status
• Configuration: Get and update Mountain configuration

Configuration

• Default Address: [::1]:50051 (Mountain’s default Vine server port)
• Transport: gRPC over TCP/IP with optional TLS
• Timeouts: Configurable connection and request timeouts

TLS/mTLS Support

The mtls feature enables TLS client support with:

• Client certificate authentication
• Secure encrypted communications
• Certificate validation against CA

Note: TLS/mTLS implementation is a stub for future enhancement. The current implementation focuses on establishing unencrypted connections for development and testing purposes.
