using docker buildx failed to push image to resgistry: no such host

Question

I have added my registry vm hostname to /etc/hosts and docker pull <registry_name>/<imagename> works. However when I try to use docker buildx build .. --push command to push to the same registry, it throws error:

Does docker buildx does not look /etc/hosts?

Answer 1

It can be achieved by setting --driver-opt to use host network.
