Compiling Node.JS on Alpine Linux

compile-node-alpine.txt

apk update
apk install curl python build-base gcc abuild binutils binutils-doc gcc-doc linux-headers
curl -L -O https://nodejs.org/dist/v4.6.0/node-v4.6.0.tar.gz
tar xzf node-v4.6.0.tar.gz
cd node-v4.6.0
./configure
make 
make install

This wouldn't book on my Amazon Linux container, but a slightly modified version would:

RUN NODE_VERSION="v9.9.0" && \
    apk add --update --no-cache curl \
    make \
    python \
    g++ \
    gcc \
    gcc-doc \
    linux-headers && \
  curl -L -O https://nodejs.org/dist/latest-v9.x/node-$NODE_VERSION.tar.gz && \
  tar xzf node-$NODE_VERSION.tar.gz && \
  cd node-$NODE_VERSION && \
  ./configure && \
  make && \
  make install

how to download npm? also, does node-gyp needs to be built as well?
