Main discovery orchestrator.
|
|
|
|
Coordinates all phases of SSH-based device discovery:
|
|
0. Resolve DB connection (explicit config or autodetect via SSH).
|
|
0.5 Pre-upsert the DB server device (so users can configure tunnels on failure).
|
|
1. Fetch rack hosts from the CAPS DB; sync Rack table entries.
|
|
1b. Upsert infrastructure devices (main_server).
|
|
2. SSH into each rack → parse CAPS config → upsert plugin devices.
|
|
2.5 Discover slave racks via ARP neighbor tables.
|
|
3. Discover MikroTik via SSH_CLIENT env var.
|
|
4. Discover Proxmox via port 8006 scan.
