DNS resolver conf

This repository is only a mirror. Development and testing is done on a private gitlab server.

This role configures dns resolvers on debian-based distributions.

Requirements

None.

Role Variables

Available variables are listed below, along with default values. A sample file for the default values is available in default/dns_resolver_conf.yml.sample in case you need it for any group_vars or host_vars configuration.

dns_resolv_conf_disable_resolvectl: false # by default, set to false

This variable determines if systemd-resolved should be kept enabled/started or not. On some systems, like dns servers, it can interfere with the actual server, and disabling it might be a good idea.

dns_resolv_conf_path: '/etc'

This variable defines the path where the resolv.conf fie should be copied.

dns_resolv_conf_nameservers: []

This variable is the list of nameservers to configure on the host.

dns_resolv_conf_domain: ""

This variable sets the domain field in resolv.conf.

dns_resolv_conf_search: []

This variable is a list of all the search domains. Ideally, only one of dns_resolv_conf_domain or dns_resolv_conf_search should be specified. The other should be left untouched.

dns_resolv_conf_sortlist: []

This variable sets the sortlist option for resolv.conf. This option is a bit obsolete, and is here only for completeness of the config.

dns_resolv_conf_options: []

This variable sets the options to pass in resolv.conf, like rotate, etc...

Dependencies

None.
