use envd to build ARM Images via ARM buildkit daemon containers

[HwangDozz]

I have deployed a BuildKit daemon container on an ARM node and exposed it as a TCP service. I want to use envd to specify these ARM-based BuildKit daemons as the backend and build images with platform=linux/arm64. Do I need to modify the baseImage in the build.envd file to use a corresponding ARM-compatible base image?

btw, I want to use ​​envd​​ and ​​buildkitd​​ for cross-platform builds—for example, simultaneously building images for both ​​linux/amd64​​ and ​​linux/arm64​​. Does ​​envd​​ support having ​​buildkitd​​ instances of both platforms in the context and automatically distribute builds based on architecture? Specifically, can it route ARM image builds to ​​buildkitd​​ running on ARM nodes?

envd build --platform specifies the target platform. However, this doesn't route to the buildkitd daemon by target platform, as you can only specify one buildkitd daemon.

If you want to get faster builds on different platforms, you might need to wrap envd to choose different buildkitd daemons based on the target platform.

Thank you for your response！
