A short checklist for small services
Before a small server fades into the background, leave a map. Note what starts the service, where its state lives, which ports are intentional, and how certificates are renewed.
Five useful answers
- What is this machine for?
- How does the service start?
- Where are configuration and persistent data?
- Which inbound ports should exist?
- How do I verify a healthy recovery?
A half-page with current answers is more valuable than a long guide that nobody maintains.
