Multi architecture builds and manifests

[psyciknz]

Can i use the existing Dockerfile for generating binaries for arm/arm64 and x86?

It seems to hang on the git pull on the arm servers.

I'm hoping to use this guys framework https://lobradov.github.io/Building-docker-multiarch-images/ to pull the right alpine images so that I can build for all archs.

No you can't, because the images are based on amd64 alpine image.

Unless I rewrote your dockerfile for arm64v8. Does that mean for the build function I need goos=Linux and goarch=arm64. I’m trying that anyway.

Oh, I misread your message. If it is simply to generate binaries, you can generate for any platform supported by Go including arm64 as indicated here.

docker run --rm -v $(pwd):/install \
  -e PLUGINS=git,filemanager \
  -e GOARCH=arm64 \
  abiosoft/caddy:builder

@abiosoft, is this webpage the equivalent of abiosoft/caddy:builder?

[abiosoft]

@maxiride Yes, that is official binaries from caddy's build servers. This image builds from source and leverages Docker. https://github.com/abiosoft/caddy-docker#license

It still doesn't pull the correct image architecture. I tried on an armv7 and received an exec format error.
I believe it has something to do with the builder script which has fixed architecture on it. After cloning and removing these lines, I managed to make it work building the docker images locally.

I don't know exactly how is the build process on dockerhub but I already seem a lot of images that have multi arch build there. eg. the images from https://www.linuxserver.io/
