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.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

# calling the role inside a playbook with either the default or group_vars/host_vars
- hosts: servers
  roles:
    - ednxzu.dns_resolver_conf
