Use buildx for cross architecture builds

[mStirner]

docker buildx build --platform linux/amd64,linux/arm64 -t openhaus/backend:x.x.x
docker tag openhaus/backend:x.x.x openhaus/backend:latest

docker push openhaus/backend:x.x.x
docker push openhaus/backend:latest

Same for other images:

• https://github.com/OpenHausIO/frontend
• https://github.com/OpenHausIO/connector
• https://github.com/OpenHausIO/admin-frontend

This is pure shit. You have to push directly into the registry:
docker buildx build --platform linux/amd64,linux/arm64 --push -t openhaus/admin-frontend:0.1.0 .

Use https://buildah.io/ instead https://danmanners.com/posts/2022-01-buildah-multi-arch/ ?

Or with ChatGPT, build single arch images, and merge them:

# Build and export amd64 image
docker buildx build --platform linux/amd64 --load -t openhaus/admin-frontend:0.1.0-amd64 .

# Build and export arm64 image
docker buildx build --platform linux/arm64 --load -t openhaus/admin-frontend:0.1.0-arm64 .

# Create multi-arch manifest
docker buildx imagetools create -t openhaus/admin-frontend:0.1.0 \
  openhaus/admin-frontend:0.1.0-amd64 \
  openhaus/admin-frontend:0.1.0-arm64
