Can't install on linux/arm64 with docker node

[gpetrov]

Trying to run a simple Dockerfile to install node together with sharp on linux/arm64 fails.

FROM node:14-slim

RUN npm i detect-libc

RUN node -e "console.log('platform=' + process.platform);console.log('arch='+process.arch);console.log(require('detect-libc'))"

RUN npm i sharp

when ran on arm64 - it produces:

There are already prebuild libvips images for arm64v8 - why aren't they used?

Running the same on Windows 10, goes actually just fine. While the arch checks is there pretty much the same:

@lovell I think the glibc check is a bit too hard and doesn't check for prebuild images first.

Hi, the salient part is:

ERR! sharp Use with glibc 2.24 requires manual installation of libvips >= 8.10.0

This is documented at https://sharp.pixelplumbing.com/install#prebuilt-binaries

Ready-compiled sharp and libvips binaries are provided for use with Node.js v10+ on the most common platforms:
...
Linux ARM64 (glibc >= 2.29)

The following platforms require compilation of both libvips and sharp from source:
...
Linux ARM64 (glibc <= 2.28, musl)

[gpetrov]

But there is no need to compile anything...?

docker image is linux/arm64 and there is a prebuild binary available.

it runs all fine in linux/x86 - while there is the same glibc 2.24

or does node needs to change all their official docker image to include glibc 2.29+ ?

[lovell]

Please see lovell/sharp-libvips@2e4202d for a discussion about why the prebuilt arm64 binaries currently require glibc 2.29+

[gpetrov]

Thanks - make sense now. Hope node updates their base images. However even latest buster image is still with glibc 2.28

Maybe you can consider to support musl? Trying docker node:14-alpine, produced:

[gpetrov]

Btw the Linux/arm64 is running natively on the new Apple Silicon M1 arm64 with the upcoming Docker Desktop version for the M1.

So it is essential to have the right binaries ready for easy docker deploy @lovell

[gpetrov]

can you clarify @lovell that you need GLIBC 2.29+ - just to run libvips? Not only to compile it?

[lovell]

As you hopefully saw from the discussion in lovell/sharp-libvips@2e4202d, gcc 9.2.0+ is required to compile libvips on arm64 without introducing compiler bugs. The oldest OS that provides gcc 9.2.0 is Debian 11, which also provides and therefore requires glibc 2.29.

[gpetrov]

Yes I saw that - but I don't need to compile libvips - the precompiled binary from sharp-libvips for arm64v8 is just fine!
https://github.com/lovell/sharp-libvips/releases/download/v8.10.0/libvips-8.10.0-linux-arm64v8.tar.gz

But your check for glibc version prevents it from being downloaded....

[lovell]

A binary compiled on Debian 11 will require glibc 2.29+ at runtime.

[gpetrov]

ok then we will have to wait for node to be available on debian bullseye ... it might take a while.

maybe there is a better hope for node-alpine with musl?

[lovell]

we will have to wait for node to be available on debian bullseye

https://packages.debian.org/bullseye/nodejs

[gpetrov]

I mean the official docker node image:

https://hub.docker.com/_/node

It doesn't have bullseye yet, so no docker node installation under arm64 can run sharp ...
