Adding SSL certificates or disabling SSL for HTTPS clients?

Is there a way to add SSL certificates to the yaks image or disabling SSL when using HTTPS clients?

We are getting the following error when calling an HTTPS endpoint from the yaks base image.
I/O error on GET request for "URL": PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

This is a very basic feature when using yaks for HTTPS integration testing. It would be great if we could disable SSL verification with a configuration.

The issue mentions the YAKS base image and HTTPS clients but names no files, tests, or entry points. Start by locating the HTTPS client configuration and how the base image supplies trust certificates. Done should provide a documented way to add certificates or configure SSL verification, with coverage for the reported PKIX failure.
