Using HashiCorp Packer to generate multi-arch Docker images

I am hoping to find someone who has experience using HashiCorp Packer to generate multi-arch Docker images. I am having trouble finding a clear example that demonstrates how to build a Docker image with multiple architectures and create a manifest for it.

If anyone has any resources or examples they can share, it would be greatly appreciated. I’m looking to learn more about the process and best practices.

Thank you in advance for your help!
