MergeDrop image build

The Dockerfile and full source for the MergeDrop image live in a separate Gitea repo:

Source: https://git.alexzaw.dev/alexz/video-merger
Published image: git.alexzaw.dev/alexz/mergedrop:<tag>

This folder holds only a thin helper script (build.sh) that clones the source repo and pushes the resulting image to the in-house Docker registry.

Rebuild

cd build/
./build.sh                                 # builds + pushes :latest and the version tag
IMAGE_TAG=1.0.1 ./build.sh                 # override the tag

Requires docker login git.alexzaw.dev to already be done (or ~/.docker/config.json to have the registry credentials, which is the case on this host).

Notes

The image is a two-stage build (Node 20 → Python 3.11-slim) and produces an amd64 image only. Add --platform linux/arm64 to build.sh args to cross-build.
The application is a single FastAPI process that serves the static React build and a /api/* JSON API on the same port (8000 inside the container).
ffmpeg is installed in the runtime image; no host-level ffmpeg required.
