The local .env file (generated by up.sh) was being copied into the Docker image via COPY, overriding Fly secrets with localhost:5432 and causing ECONNREFUSED on every deploy built from a local machine.

Summary
.envto.dockerignoreto prevent local dev config from being baked into Docker imagesContext
up.shgenerates a.envfile withDATABASE_URL=postgresql://...@localhost:5432/.... This file is gitignored but NOT dockerignored, soCOPY . .copies it into the image. On Fly,loadEnv.tsreads the.envfile before checkingDeno.env.get(), so the local DATABASE_URL overrides the Fly secret — causingECONNREFUSED 127.0.0.1:5432on every locally-built image.CI builds are unaffected (clean checkout has no
.env), but this prevents deploying from a local machine after runningup.sh.Test plan
