Have you had any luck with this? We are running into a similar problem

The OP did hide the relevant details that would help to understand the situation. I guess it is the reason it never received any response, other than yours.

Please create your own topic, describe your current situation and share the original Dockerfile you experience the problem with, so we get a chance to actually see what you do. Leave everything as is, and only redact credentials / secrets (both should actually not exist in a Dockerfile), private ips or private domains.
