Cold Comm Protocol Breach: Fastify Isolated

The Standoff: “The Radio Says Clear But The Area Is Still In Chaos.”
The logs claimed victory:
Fastify operational. Port secured.
Meanwhile, recon from the browser frontlines screamed:
“Connection refused. Page isn’t working.”
The backend was inside a Docker-controlled zone. A perfectly good Fastify instance, armed and ready. But our browser? No comms. Total blackout. Outside the fences.
Like shouting across a demilitarized zone with a banana for a radio.
Recon Report
- Fastify was broadcasting from its default internal port.
- Docker’s port mapping was a misfire — translating wrong coordinates to the external world.
- Command mistakenly issued a same-same mapping (
{custom}:{custom}), assuming backend compliance. - Fastify, of course, stayed on its own post, unaware of the diplomatic blunder.
The Strategic Adjustment: Correct the Map
The fix was pure logistics.
Docker doesn’t guess your intentions — it just routes traffic based on the map you draw.
# docker-compose.yml
ports:
- "<external-port>:<fastify-internal-port>"Once HQ aligned the Fastify default post with Docker’s port mapping, the line lit up. Clean signal. Browser forces made contact.
Outcome of Operation: BACKEND-HAIL
- Fastify finally answered the call âś…
- Mapped ports correctly, respecting chain of command âś…
- No exposed internal ports — radio silence for enemy eyes ✅
- Browser got its intel. Mission success. âś…
- Lesson learned: Docker isn’t psychic, it’s literal. Bring your own map. ✅
Backend is operational. No error signals. No success confirmation either. Too quiet. Suspiciously quiet. We're keeping watch.
End of log. (Filed: /dev-logs. Morale: Low. The answer was right in my nose.)
