CoreDNS-005 has been released!
CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
What is New
A way to configure (external) plugin was added. Edit
plugin.cfg and do a
go generate && go
build and your plugin has been added. This allows for out-of-tree plugin to be easily
added. Documentation can be found in
- erratic: a new plugin that can drop queries, limited in the current functionality, but useful for testing.
- trace: a new plugin that implements OpenTracing-based tracing using Zipkin.
- proxy: fix a bug when a connection hangs and never gets release (#467)
- proxy: Fold httpproxy into it, which is now a normal proxy with a special
protocol. For Monitoring an extra label was added:
proxy_protothat shows the protocol used (
https_google). See the proxy README.md for details.
- httpproxy: removed because functionality is moved to proxy.
- kubernetes: Now implements the full Kubernetes DNS Specification, including regular and headless services, endpoint hostnames, A, SRV, and PTR records.
- kubernetes: Implements the
podtype for requests in both a Kube-DNS compatible mode (
insecure) and a mode which validates that the IP in question belongs to a pod in the specified namespace (
- kubernetes: Simplified the configuration of reverse zones. Instead of listing the zones in the
zone list, you can just add a list of CIDRs using the
- rewrite: allow rewriting more bits of the incoming packet. This required some backward incompatible changes, e.g. a new FIELD keyword is now required. See the rewrite README.md for details.
