I'm trying to use Hashicorp Packer to create and upload an AWS VM. I'm behind a http and https proxy, so when I set http_proxy and https_proxy (and HTTP_PROXY and HTTPS_PROXY) I can use the aws cli to see my S3 containers with no problems; however Hashicorp Packer uses the AWS go libraries, and according to https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html#configuring-a-proxy and https://golang.org/pkg/net/http/#Transport they +only+ support HTTP_PROXY and not HTTPS_PROXY.
Is there any way I can use the AWS Go library (or packages built using it, like Packer) with a HTTPS proxy?
