Pomerium v0.32.0 adds DNS configuration options, giving you direct control over how Pomerium resolves upstream hostnames. Instead of relying solely on the host system's resolver, you can now point Pomerium at specific DNS servers and tune how often it refreshes records — useful for split-horizon DNS, service discovery, and environments where upstream IPs change frequently.
Highlights:
Custom resolvers – Specify the DNS servers Pomerium should use to resolve upstream routes, independent of the underlying host configuration.
Tunable refresh behavior – Configure DNS refresh rates so Pomerium picks up record changes on a schedule that matches your environment, rather than caching stale addresses.
Consistent upstream resolution – Predictable, centrally configured name resolution across all Pomerium components, which matters most in dynamic and clustered deployments.
See the Pomerium configuration reference for the new DNS options.
