Arm64 support for Apple Silicon chip

[j796160836]

Hi,
Please add arm64 support although it's hello world project.
Busybox (base image) has support arm64. I think just rebuild it will be ok. Thanks.

sorry I don't know when I'll be able to get to this. I'm between computers right now and I kind of stopped using Docker CLI

I solved in my fork.

Here is new build command, you need to install buildx command.

https://docs.docker.com/buildx/working-with-buildx/

1. Login to docker hub before build.

$ docker login

then enter your credentials.

2. Build and push to registry, remember specify the architecture. (Don't forget the final dot. 🙂)

$ docker buildx build --push -t crccheck/hello-world:latest --platform linux/amd64,linux/arm64,linux/arm/v7 .

Check your docker hub's page, it will list multiple architecture in list.
By the way, don't use docker push command. It will upload only one architecture.

I ended up installing Rancher Desktop (not Docker Desktop) on my M1 Mac and wasn't able to recreate the problem.

As for Docker Desktop users, maybe I can adjust the CI script to publish a buildx build

[cernoel]

you can try my image cernoel/hello-world:main .. if this works .. @crccheck might pull my changes in the publish.yaml to fix this? .. at least it works in my case for the ampere (arm64) servers.

Notice that if you do not specify the platform, running may still fail. Good way: docker run --platform linux/arm64 -d -p 80:80 j796160836/simple-test-http
