Fixed bug in node:16-alpine Dockerfile that appears on arm64 architecture

[nikelborm]

Bug:
I was unable to use yarn on arm64 architecture

Description

I normally used node:16-alpine in my docker file. It works fine on amd64 architecture. Then I was needed to build an arm64 image of the container. And there happened a problem.

Simplified Dockerfile for this example:

FROM node:16-alpine
RUN yarn --version

Output of docker buildx inspect:

Name:   mybuilder
Driver: docker-container

Nodes:
Name:      mybuilder0
Endpoint:  unix:///var/run/docker.sock
Status:    running
Platforms: linux/arm64*, linux/amd64*, linux/amd64/v2, linux/amd64/v3, linux/386

Command I use to build container for both architectures:

docker buildx build --push --platform=linux/amd64,linux/arm64/v8 -t nikelborm/home:front-latest .

Previous command causes this output:

From this output, we can see that the problem appears only on arm64 arch.

I started to research this problem and found that everything was fine except for, well, there is no either /usr/local/sbin, neither /usr/local/sbin/node

I checked both arm64 and amd64 images of node:16-alpine and both of them doesn't have /usr/local/sbin directory. I don't know why but it becomes a problem only for arm64 build.

I changed my Dockerfile to

FROM node:16-alpine
RUN node --version

# RUN mkdir /usr/local/sbin; ln -ns /usr/local/bin/node /usr/local/sbin/node || true

RUN ls -AlF --group-directories-first /usr/local/ && \
  echo -e '\n' &&\
  ls -AlF --group-directories-first /usr/local/bin && \
  echo -e '\n' &&\
  printenv && \
  echo -e '\n' &&\
  which node && \
  echo -e '\n' &&\
  cat /opt/yarn-v1.22.18/bin/yarn &&\
  echo -e '\n' &&\
  yarn --version

Output was like that:

I want to pay attention to which node because it shows that node.js is placed in /usr/local/bin/node

mkdir /usr/local/sbin will throw an error when alpine team will create this directory, but the error will be ignored because of ; .
Then I added a link to node js and then everything started work fine

Testing Details

I tried to build this Dockerfile

FROM node:16-alpine

RUN mkdir /usr/local/sbin; ln -ns /usr/local/bin/node /usr/local/sbin/node || true

RUN yarn --version

And build was successfull on both architectures

This sounds like an issue between Yarn and QEMU, and not likely something we'd patch here
