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'.
Related, whomever is specifying quay.io needs to specify 'quay.io.',
with the trailing dot. The trailing dot signifies a Fully Qualified
Domain Name (FQDN). The trailing dot means the dns name starts at the
top of the DNS tree, and search domains won't (should not?) be added.
Or maybe I should say, won't be added in a proper functioning
implementation.
