Role deploy_systemd_resolved_config

A role for deploying a minimal configuration for systemd-resolved or alternatively completely disabling it.

!! Note If systemd-resolved is disabled, the configuration is instead rendered directly into /etc/resolv.conf to ensure a node does not accidentally lose name resolving capabilities.

Optional Arguments

• deploy_systemd_resolved_config__enable (defaults to true) decides whether systemd-resolved should be enabled or disabled.

• deploy_systemd_resolved_config__mode (defaults to stub) controls which compatibility mode is used for /etc/resolv.conf when systemd-resolved is enabled. See man systemd-resolved(8).

• deploy_systemd_resolved_config__dns is the list of primary DNS servers that will be configured. If e.g. a specific link configures other DNS servers, they will take precedence.

• deploy_systemd_resolved_config__fallback_dns (defaults to Quad9) is the list of fallback DNS servers. If, at runtime, none of the configured primary DNS servers are reachable, these servers will be used as fallback.

Hosts

This role is included as a dependency to base_config and therefore does not need to be explicitly pulled in.
