Context

Thanks for following the contribution process, if we had started there, it might have meant getting to this point a little sooner.

Why is that? Can you help us understand so we can triage this?

hi Alex, I can answer this, faasd is deployed on an internal network with no external connectivity. Hence there is a requirement to override to set it to organizations nameserver and search. dns and dns.search parameters. Please do you know if this will be fixed any time soon.

Kind Regards, Amar.
