.dockerignore is now an allowlist (go.mod, go.sum, cmd, internal, web), so data, backups, .env and anything a deploy tool keeps in the project folder never go into the build context. A file changing or failing to read while the context is sent cuts the upload short, which Docker reports as "failed to read dockerfile: unexpected EOF". Also drops a stray blank first line from the Dockerfile. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
