CoreDNS-0.9.9 has been [released](https://github.com/coredns/coredns/releases/tag/v0.9.9)!
|
|
(yes, we've moved to [semver](https://coredns.io/2017/09/16/semantic-versioning/))
|
|
|
|
CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
|
|
|
|
Release 0.9.9 is a major release, with lots of fixes.
|
|
|
|
## Core
|
|
|
|
* We've renamed `middleware.Middleware` to `plugin.Plugin`. This is backwards incompatible for external ~~middleware~~ plugins, but you can update your plugin by just replacing `[Mm]iddleware` with `[Pp]lugin`:
|
|
~~~
|
|
sed 's/Middleware/Plugin/'g -i *.go
|
|
sed 's/middleware/plugin/'g -i *.go
|
|
~~~
|
|
From now on we'll use the term *plugin* in our documentation and code.
|
|
|
|
* We've sent a proposal to make CoreDNS the default in Kubernetes: https://github.com/kubernetes/community/pull/1100
|
|
|
|
## Plugins
|
|
|
|
* *etcd*'s debug queries are removed.
|
|
* *hosts* gets inline host definitions that add or overwrite those from `/etc/hosts`.
|
|
* *auto*, *file* now poll every minute for on disk changes (inotify wasn't working).
|
|
* *rewrite* can chain rules and perform multiple changes on a message.
|
|
* *kubernetes* uses `protobuf` to communicate with the kubernetes API and
|
|
performance improvements when there are a large number of services.
|
|
* *dnstap* saw several fixes, including sending tap messages out-of-band.
|
|
* *cache* apply configured TTL to first answer returned.
|
|
* Don't cache TTL=0 messages.
|
|
* *proxy* smaller timeouts and the health check GET was given a timeout.
|
|
* Better metrics: add a request counter metrics and change the 'from' label to 'to' so we count/duration per upstream.
|
|
* *dnssec* now signs NODATA responses.
|
|
|
|
## External Plugins
|
|
|
|
Two new [external plugins](/explugins) were added:
|
|
|
|
* *ipecho* parses the IP out of a subdomain and echos it back as an record.
|
|
* *forward* facilitates proxying DNS messages to upstream resolvers.
