Hi Joel, kubernetes is using the AWS inventory information directly as soon as it detects the AWS cloud. Until now I did not find any solution to get to nice hostnames.
Instead we label the "nice name" as "host" (oc label node .... host=abc) and use "oc get node -L host" to get the names listed. 2018-02-21 13:13 GMT+01:00 Joel Pearson <japear...@agiledigital.com.au>: > Hi, > > I'm trying to figure out how to use the DNS hostname when deploying > OpenShift on AWS using https://github.com/openshift/openshift-ansible- > contrib/tree/master/reference-architecture/aws-ansible Currently it uses > private dns name, eg, ip-10-2-7-121.ap-southeast-2.compute.internal but > that isn't too useful a name for me.
