CoreDNS-002 has been released!

CoreDNS is a DNS server that chains plugins, where each plugin implements a DNS feature.

What is New

• -port was renamed to -dns.port to avoid clashing with Caddy’s -port (which was renamed to http.port).
• Lumberjack logger was removed, this means no built in log rotation; use an external tool for that.
• Brushed up GoDoc for all packages.
• Brushed up all READMEs to be more standard and look like manual page.
• Golint-ed and go vet-ed the code - these can now (somewhat) useful tools before submitting PRs.
• Add more tests and show test coverage on submitting/PRs.
• Various Corefile parsing bugs fixed, better syntax error detection.

Plugin improvements:

• plugin/root: a root plugin, same usage as in Caddy. See plugin/root/README.md for its use in CoreDNS. This makes stanzas like this shorter:

  .:53 {
      file /etc/coredns/zones/db.example.net example.net
      file /etc/coredns/zones/db.example.org example.org
      file /etc/coredns/zones/db.example.com example.com
  }
  

  Can be written as:

  .:53 {
      root /etc/coredns/zones
      file db.example.net example.net
      file db.example.org example.org
      file db.example.com example.com
  }
  

• plugin/auto: similar to the file plugin, but automatically picks up new zones. The following Corefile will load all zones found under /etc/coredns/org and be authoritative for .org.:

  . {
      auto org {
          directory /etc/coredns/org
      }
  }
  

• plugin/file: handle wildcards better.

• plugin/kubernetes: TLS support for kubernetes and other improvements.

• plugin/cache: use an LRU cache to make it memory bounded. Added more option to have more control on what is cached and for how long. The cache stanza was extended:

  . {
      cache {
          success CAPACITY [TTL]
          denial CAPACITY [TTL]
      }
  }
  

  See plugin/cache/README.md for more details.

• plugin/dnssec: replaced go-cache with golang-lru in dnssec. Also adds a cache_capacity. option in dnssec plugin so that the capacity of the LRU cache could be specified in the config file.

• plugin/logging: allow a response class to be specified on log on responses matching the name and the response class. For instance only log denials for example.com:

  . {
      log example.com {
          class denial
      }
  }
  

• plugin/proxy: performance improvements.
