CoreDNS-011 has been [released](https://github.com/coredns/coredns/releases/tag/v011)!
|
|
|
|
CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.
|
|
|
|
Release v011 is a major release, with backwards incompatible changes in the *kubernetes* plugin.
|
|
|
|
## Core
|
|
|
|
**This release has backwards incompatible changes** for the *kubernetes* plugin.
|
|
|
|
* Stop vendoring `github.com/miekg/dns` and `golang.org/x/net/context`. This enables external plugin to compile without tripping over vendored types that mismatch.
|
|
* Allow an easy way to specify reverse zones in the Corefile, just use (e.g) `10.0.0.0/24` as the zone name,
|
|
CoreDNS translates this to 0.0.10.in-addr.arpa. This is only done when the netmask is a multiple of 8 and for both IPv4 and IPv6.
|
|
* Bug and stability fixes.
|
|
|
|
## Plugins
|
|
|
|
Make *kubernetes*, *file*, *secondary*, *hosts*, *erratic* and *metrics* now fail on unknown properties in the Corefile.
|
|
|
|
### New
|
|
|
|
* *federation*: enables federation via kubernetes.
|
|
* *autopath*: enables autopath-ing. Can be used standalone, but its main use is with kubernetes.
|
|
|
|
### Updates
|
|
|
|
* *log* adds an `>rflags` replacer that shows the flags from the response - this has been enabled by default.
|
|
* *kubernetes* deprecates:
|
|
* `cidr`: use the reverse syntax in the Corefile
|
|
* `federation`: use the new *federation* plugin
|
|
* `autopath`: use the new *autopath* plugin
|
|
* *kubernetes*:
|
|
* add TTL option allowing to set minimal TTL for responses.
|
|
* Multiple k8s API endpoints could be specified, separated by `","`s, e.g. `endpoint http://k8s-endpoint1:8080,http://k8s-endpoint2:8080`. CoreDNS will automatically perform a healthcheck and proxy to the healthy k8s API endpoint.
|
|
* *rewrite*:
|
|
* allow for *dynamic* properties to be used, like client IP address in rewrite rules, i.e.
|
|
`rewrite edns0 local set 0xffee {client_ip}`
|
|
* add support for EDNS0 Client Subnet
|
|
* *dnstap* now reports messages proxied by *proxy*, and support remote IP endpoints by specifying `tcp://`.
|
|
* *dnssec* now warns if keys can't be used to sign the configured zones.
|
|
* *health* now allows for per plugin health status; no plugin makes use of this yet, though.
|
|
* *secondary* parses a secondary with a zone (`secondary example.org {...}`) correctly.
