Container Inventory

The server runs multiple Docker containers. Memory is constrained (1.9 GB + 1 GB swap), so only essential containers should be running.

Running Containers (Essential)

Container	Image	Memory	Purpose
max	n8nio/n8n:latest	~370 MB	Max Shipping N8N — chatbot webhook + MCP
caddy	caddy	~18 MB	Reverse proxy + auto SSL for all subdomains
postgres	postgres	~40 MB	Shared database for all N8N instances
watchtower	containrrr/watchtower	~10 MB	Auto-updates Docker images
python-svc	python-svc:latest	~31 MB	Python service (port 8000)
n8n-audio-server	nginx:alpine	~3 MB	Audio file server (port 8081)

Stopped Containers

Stopped 2026-02-21 to free memory. All data is preserved — docker start <name> brings them back.

Caddy Reverse Proxy Routes

max.lifeonroatan.net      → max:5678
mcp.max.lifeonroatan.net  → max:5678
n8n.lifeonroatan.net      → n8n:5678
mcp.n8n.lifeonroatan.net  → n8n:5678
dev1.lifeonroatan.net     → n8n-dev1:5678
mcp.dev1.lifeonroatan.net → n8n-dev1:5678
dev2.lifeonroatan.net     → n8n-dev2:5678
mcp.dev2.lifeonroatan.net → n8n-dev2:5678

All containers are on the proxy Docker network.
