CoreDNS-008 has been [released](https://github.com/coredns/coredns/releases/tag/v008)!
|
||
|
|
|
||
|
|
CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
|
||
|
|
|
||
|
|
Release v008 has a lot of content, with new plugin and major features added to existing plugin.
|
||
|
|
|
||
|
|
Please note there is an *incompatible* change to the `log` directive - it now only logs to `stdout` and so
|
||
|
|
only allows `stdout` as the file name (which of course may be omitted).
|
||
|
|
|
||
|
|
# Core
|
||
|
|
|
||
|
|
* `-log` flag was changed into a boolean as all logging will be written to standard output.
|
||
|
|
|
||
|
|
# Plugins
|
||
|
|
|
||
|
|
## New
|
||
|
|
|
||
|
|
* *hosts* allows CoreDNS to read a `/etc/hosts` styled file and generate responses from that.
|
||
|
|
* *debug* can disable the `panic/recover` that is enabled by default. Mostly useful for testing/non-prod use cases to generate stack traces.
|
||
|
|
|
||
|
|
## Updates
|
||
|
|
|
||
|
|
* *chaos* now returns the correct `version.bind` `TXT` record.
|
||
|
|
* *kubernetes*
|
||
|
|
* Now returns a proper NS record for the cluster domain
|
||
|
|
* Supports `ExternalName` services, which was an oversight in the 1.0.0 version of the [Kubernetes dns spec](https://github.com/kubernetes/dns/blob/master/docs/specification.md)
|
||
|
|
* Now supports federation records
|
||
|
|
* Has had some other bug fixes.
|
||
|
|
* *file*
|
||
|
|
* Now supports DNAME [RFC 6672](https://tools.ietf.org/html/rfc6672)
|
||
|
|
* Refuse to load a zone without a SOA record.
|
||
|
|
* *file, auto* don't reload a zone when the SOA's serial hasn't changed.
|
||
|
|
* *secondary* now behaves properly if queried before the zone has been transferred
|
||
|
|
* *log, errors* output everything to *stdout* and let `journald` or `docker` (or whatever) that care of further handling. This is backwards **incompatible** change wrt to the Corefile: `log query.log` will return an error.
|
||
|
|
* *cache* got a new cache implementation to be more scalable and a new `prefetch` option for fetching records before the TTL expires.
|
||
|
|
* *proxy* does not use `singleinflight` anymore, removing a potential bottleneck on the single mutex in that implementation; it now forwards *all* queries it get to the upstream nameserver.
