Functions

func Check

func Check(tld string) (bool, error)

Check resolves test-lerd-probe.{tld} and checks if 127.0.0.1 is in the results. Returns (true, nil) if DNS is working correctly for the given TLD.

func ConfigureResolver added in v0.1.53

func ConfigureResolver() error

ConfigureResolver configures the system DNS resolver to forward .test to the lerd-dns dnsmasq container on port 5300. Call this after lerd-dns is running so that any immediate resolvectl changes don't break DNS before dnsmasq is up.

func InstallSudoers added in v0.3.0

func InstallSudoers() error

InstallSudoers writes a sudoers drop-in granting the current user passwordless access to resolvectl commands. This is required for the autostart service which runs non-interactively and cannot prompt for a sudo password.

func Setup deprecated

func Setup() error

Setup writes DNS configuration for .test resolution and restarts the resolver. On systemd-resolved + NetworkManager systems (Ubuntu etc.) it uses an NM dispatcher script. On pure systemd-resolved systems it uses a resolved drop-in. On NetworkManager-only systems it uses NM's embedded dnsmasq.

Deprecated: prefer calling WriteDnsmasqConfig then ConfigureResolver separately so that the dnsmasq container can be started between the two steps.

func Teardown added in v0.1.55

func Teardown()

Teardown removes all lerd DNS configuration from the system and restores normal resolution.

func WaitReady added in v0.4.3

func WaitReady(timeout time.Duration) error

WaitReady blocks until lerd-dns is accepting TCP connections on port 5300 (dnsmasq supports DNS over TCP), or until the timeout elapses. Returns nil when ready, error on timeout.

func WriteDnsmasqConfig

func WriteDnsmasqConfig(dir string) error

WriteDnsmasqConfig writes the lerd dnsmasq config to the given directory. Upstream DNS servers are detected from the running system (DHCP / systemd-resolved). If no upstreams are detected, no-resolv is omitted so dnsmasq falls back to the container's /etc/resolv.conf (populated by Podman from the host's DNS config).
