/kind feature

Description

This feature has been asked on Podman Desktop side, here is a transcript:

DNS resolution error when pulling images with vpn enabled.

My company requires and enforces a VPN on company hardware. The /etc/resolv.conf in the Podman machine vm that is created by Podman Desktop is initialized with the dns of the host and not the VPN. Tom Sweeny had a great post about getting Podman up and running in WSL and following his post i was able to edit the /etc/resolv.conf nameserver in WSL with the dns of the vpn.

I know this may be an edge case, but it would be tremendously helpful to have an option in podman desktop to set the nameserver in the /etc/resolv.conf of the podman machine.

Describe the results you received:
DNS used = vpn DNS

Describe the results you expected:
DNS used = dns of the host

This issue has been superseded by the user-mode-networking feature, which will provide a more complete solution (connectivity to services behind the VPN will also work). We could always reopen this if for some reason user-mode is too much.
