Docker buildx docker-container builder failing, i/o timeout when pulling remote image

[chrisforrette]

I'm new to Docker buildx and trying to test the S3 cache backend locally using a docker-container builder but when I try to build an image it keeps failing with a timeout when trying to pull the remote images' metadata that my Dockerfile is referencing:

docker buildx build . --platform linux/amd64 -f Dockerfile.test

But a Docker pull (docker pull ubuntu:18.04) on the host machine works fine.

I've tried creating the builder with a variety of flags, including with and without --driver-opt "network=host" with the same result. This is what my last invocation looked like:

docker buildx create --driver docker-container --buildkitd-flags "--allow-insecure-entitlement security.insecure --allow-insecure-entitlement network.host" --platform linux/amd64,linux/arm64/v8 --driver-opt "network=host" --use --bootstrap

And for context it's using the desktop-linux content that I believe comes with Docker desktop:

› docker context ls

The docs seem to be pretty light and I've had a hard time finding any relevant search results, does anyone know what I'm missing here?
