failed to run any build if using a builder instance with multiple native nodes #675
Description
I want to try building multi-platform images using one builder instance with multiple nodes(docker daemon) as that in buildx README.
steps:
- one arm64 node with docker daemon remote API enabled
- one x86 node, create docker context arm-builder, create build instance with two nodes(x86 and arm)
- build multi-platform images
following is detailed commands result
