CoreDNS – Support for AVC Resource Record

2017-04-21/in BLOG/by Wolfgang Riedel

I am more then happy to announce that Miek Gieben took a stab to implement AVC Resource Record support for CoreDNS with pull request #480. CoreDNS is a DNS server that chains middleware. Each middleware implements some DNS feature, like service discovery.

Currently CoreDNS supports (among others) the following middlewares:

chaos: respond to CH class queries
dnssec: on-the-fly DNSSEC signing of records
etcd: SkyDNS replacement
file: serve DNS from a set of files
health: simple health check
kubernetes: use CoreDNS as a KubeDNS replacement
loadbalance: shuffle A and AAAA records
metrics: Prometheus metrics
pprof: Go profiling
proxy: forward queries to an upstream (recursive) server
rewrite: rewrite incoming queries
secondary: be a secondary nameserver and retrieve zones from a primary

This is the next step forward in our journey to use DNS and the DNS-AS idea as a method for central policy control for application intent, no matter if it’s for network devices, operating systems or containerized environments.

Miek, many thanks for your support!
