/etc/resolv.conf configuration file defines the system-wide DNS
resolver configuration. It is a central location to configure the DNS
nameservers, search domains and other options. In modern Linux systems, many
services might want to change that configuration file to enable their
functionality - NetworkManager,
being several examples of that.
To avoid clashes between various software packages modifying the
/etc/resolv.conf file, the
resolvconf package provides a stable API
/etc/resolv.conf that combines information from other services
and creates a consistent resolver configuration.
debops.resolvconf Ansible role further updates the
configuration to fix issues with outdated defaults on modern Debian/Ubuntu
hosts. By default the role will update the interface order list to include the
Predictable Network Interface Names as well as clarify the order of the
NetworkManager interfaces. The role will also automatically rearrange the
configuration of VPN tunnels if a local DNS resolver is detected.
Contrary to its name, the
debops.resolvconf role does not configure the
/etc/resolv.conf file directly. You should consult the documentation of
various DNS-related services to see how you can modify the contents of this
file through them.
