/**
|
|
* Bootstrap script for the distroless production image.
|
|
*
|
|
* Distroless images have no shell, so this Node.js script handles two tasks
|
|
* that would normally be done in an entrypoint.sh:
|
|
*
|
|
* 1. Regenerate `public/__ENV.js` with the current runtime NEXT_PUBLIC_*
|
|
* environment variables. The file was originally created at build time by
|
|
* next-runtime-env's `configureRuntimeEnv()`, but in a Docker deployment the
|
|
* env vars are provided at *run* time via docker-compose / docker run.
|
|
*
|
|
* 2. Start the Next.js standalone server.
