How to disable DNS search received by DHCP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I am looking for some help to adjust systemd-resolved to still use DHCP (ip, gateway and dns servers) but to avoid using the dns search provided over DHCP.

The reason behind is that OKD4's coredns (Fedora CoreOS) appends the search stanza (first entry) that is taken from the host and then sends it to the upstream server.
Ex:
/etc/resolv.conf contains:
search my.domain my.other.domain

CoreDNS query becomes 'quay.io.my.domain' instead of 'quay.io'.


P.S.: I have an ugly workaround where I unlink and create /etc/resolve.conf but that can't be the only solution.

Best Regards,
Strahil Nikolov
