Usage

FROM node as builderWORKDIR /appCOPY package.json package-lock.json index.js ./RUN npm install --prodFROM astefanutti/scratch-nodeCOPY --from=builder /app /ENTRYPOINT ["node", "index.js"]

Note that native modules need to be statically compiled with musl to be loadable. This can easily be achieved by updating the above example with:

FROM node:alpine as builderRUN apk update && apk add make g++ python...RUN LDFLAGS='-static-libgcc -static-libstdc++' npm install --build-from-source=FROM astefanutti/scratch-node...

Build

The image can be built by executing the following commands:

$ git clone https://github.com/astefanutti/scratch-node& cd scratch-node$ docker build --build-arg version= --build-arg arch= .
