Node is about 60mb on it's own.
Taking a peak at the official dockerfile for alpine node (https://github.com/nodejs/docker-node/blob/28ad5e0e5d0e80df44d897c9057ffd6419a3c7a5/19/alpine3.16/Dockerfile https://github.com/nodejs/docker-node/blob/28ad5e0e5d0e80df4...), they're also pulling in the following packages
&& apk add --no-cache --virtual .build-deps-full \
binutils-gold \
g++ \
gcc \
gnupg \
libgcc \
linux-headers \
make \
python3
My guess is the most weight is probably coming from linux-headers (~10mb), python3 (~50mb), and nodejs (~60mb). Plus 1 to 10 mb for each of the other pacakges, and you end up right there around 175mb.
- makapuf 4y agoWhy does a minimal nodejs 19 distro need python3 ?
- arkx 4y agoMy understanding is that it’s because of node-gyp, used to build native addon modules for Node.js.
- horsawlarway 4y agoYeah, I looked again and it looks like they're actually only pulling those packages in when they need to build node for the current ARCH. (that's what I get for just scanning to the first call to apk add) They also appear to be cleaning them up, so I'm not actually sure where all that extra weight is coming from. Node itself is fairly trimmed down in the packages for alpine (40MB installed), but they're not using that package, they're pulling in their own version from their download sources - so it's possible they're including a lot of extra junk there. They also add yarn which is another 10mb. But in general - I agree, there's about 100mb of weight I can't actually explain in that image from a very quick look.
