@trini@floss.social I do sometimes, following basically this: https://docs.docker.com/build/building/multi-platform/#multiple-native-nodes
Something like this, specifying the addresses of your AMD64 and ARM64 workers:
docker buildx create --name cluster --driver remote --platform linux/amd64,linux/386 tcp://localhost:1235
docker buildx create --name cluster --append --platform linux/arm64 tcp://localhost:1234
