dns-controller creates DNS records
|
|
|
|
In the bring-up of a new cluster, protokube has already ensured that we have an etcd cluster and an apiserver. It also
|
|
sets up DNS records for the etcd nodes (this is a much simpler problem, because we have a 1:1 mapping from an etcd
|
|
node to a DNS name.)
|
|
|
|
However, none of the nodes can reach the api server to register. Nor can end-users reach the API. In future
|
|
we might expose the API server as a normal service via Type=LoadBalancer or via a normal Ingress, but for now
|
|
we just expose it via DNS.
|
|
|
|
The dns-controller recognizes annotations on nodes.
|
|
|
|
`dns.alpha.kubernetes.io/external` will set up records for accessing the resource externally
|
|
|
|
`dns.alpha.kubernetes.io/internal` will set up records for accessing the resource internally
|
|
|
|
The syntax is a comma separated list of fully qualified domain names.
