CoreDNS-003 has been released!

CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.

What is New

Core

Refused queries are properly logged and exported if metrics are enabled.

Plugin improvements

• proxy: allow /etc/resolv.conf to be used in the configuration.
• metrics: add tests and normalize some of the metrics. Removed the AXFR size metrics.
• cache: Added size and capacity of the cache (for both denial and success cache types). Don’t cache meta data records and zone transfers.
• dnssec: metrics were unused, hooked them up: export size and capacity of the signature cache.
• loadbalance: balance MX records as well.
• auto: numerous bugfixes.
• file: fix data race in reload process and also reload a zone when it is mved (newly created) into place. Also rewrite the zone lookup algorithm and be more standards compliant, esp. in the area of DNSSEC, wildcards and empty-non-terminals; handle secure delegations.
• kubernetes: vendor the k8s dependency and updates to be compatible with Kubernetes 1.4 and 1.5. Multiple cleanups and fixes. Kubernetes services can now be resolved.
