### Question

I'm running Localstack inside minikube on macOS. Due to the networking configuration in macOS, I need to use an HTTP proxy whenever I'm connected to a VPN.

This means that Localstack fails to start inside minikube when the host is connected to a VPN. The issue came up when Localstack tried to download https://github.com/localstack/localstack-artifacts/raw/master/local-certs/server.key.

Is there a way to tell Localstack to use an HTTP proxy when downloading resources?
