failing to build on raspi zero w

[hemna]

Environment

• Platform: Linux raspberrypi 5.10.52+ #1440 Tue Jul 27 09:53:08 BST 2021 armv6l GNU/Linux. (Raspberry pi Zero W)
• Docker Version: 20.10.8
• Node.js Version:
• Image Tag: node:current-alpine3.14

I am trying to build the Dozzle project's Dockerfile on my Raspberry pi Zero W: https://github.com/amir20/dozzle/blob/master/Dockerfile

The raspizerow is a linux/arm/v6 platform, so I have modified the Dockerfile to use

Build assets

FROM node:current-alpine3.14 as node

Since node:current-alpine3.14 is listed as having an armv6 image in hub.docker.com here: https://hub.docker.com/layers/node/library/node/current-alpine3.14/images/sha256-bc838a6daf88a490c81c3a85e77c65f1580d0c736fe0bbab29e32583a76afbaf?context=explore

I pulled the image locally with: docker pull --platform=linux/arm/v6 node:current-alpine3.14

I can't even get past the first command in the Dockerfile, which is RUN apk update

Not sure if you have fixed this issue. Because you added a new paramater --platform=$BUILDPLATFORM and move to latest version already (node:19-alpine)

But from my view, you don't have to nominate the platform when run the build on proper platform already.

FROM node:19-alpine as node

This image node:19-alpine included multi-arch already.

(not sure why it missed linux/arm/v7, but this is not related to current problem)

when docker build on platform linux/arm/v6 , it will pull the image for that platform automatically.

If you stuck at begin, maybe you point to wrong platform with --platform=$BUILDPLATFORM

If you need build for multi-arch, use command docker buildx, you can take the reference on this file I did

docker buildx build --no-cache --push \
   --platform linux/amd64,linux/arm/v6,linux/arm/v7,linux/arm64/v8,linux/ppc64le,linux/s390x \
   -t ${image}:latest -t ${image}:${VERSION} .
