etcd

etcd enabled reading zone data from an etcd instance. The data in etcd has to be encoded as a message like SkyDNS.

The etcd middleware makes extensive use of the proxy middleware to forward and query other servers in the network.

Syntax

etcd [zones...]

• zones zones etcd should be authoritative for.

The will default to /skydns as the path and the local etcd proxy (http://127.0.0.1:2379). If no zones are specified the block's zone will be used as the zone.

If you want to round robin A and AAAA responses look at the loadbalance middleware.

etcd [zones...] {
    stubzones
    path /skydns
    endpoint endpoint...
    upstream address...
    tls cert key cacert
}

• stubzones enable the stub zones feature.
• path the path inside etcd, defaults to "/skydns".
• endpoint the etcd endpoints, default to "http://localhost:2397".
• upstream upstream resolvers to be used resolve external names found in etcd.
• tls followed the cert, key and the CA's cert filenames.
