Doc Type: Enhancement
Doc Text:
Because nodes are now labeled with node-role.kubernetes.io/$role=true when listing nodes via `oc get nodes` you will not see the roles associated with a given node. Common node roles being `master` `compute` or `infra`. A node may be assigned multiple roles.

Description Wang Haoran 2017-12-13 05:49:58 UTC 
Description of problem:

When run oc get node on the master, the ROLES colume shows none.

oc get node
NAME                            STATUS                     ROLES     AGE       VERSION
ip-172-18-15-136.ec2.internal   Ready                      <none>    7h        v1.8.1+0d5291

the "ROLES" colum are generated by the node label "kubernetes.io/role", see the code

We need add a default label for the node, master, so we can list the correct role when we run "oc get node", we can workround by set "openshift_node_labels" param in the inventory file, but in my mind, this label should be a default value.

Version-Release number of the following components:
master branch

Comment 1 Scott Dodson 2018-01-24 15:14:40 UTC 
This is a 3.10 blocker as we intend to make use of this new labeling there but it shouldn't block any functionality in 3.9.
Comment 2 Clayton Coleman 2018-03-26 03:30:45 UTC 
This is mostly fixed in my 3.10 changes.  I plan to change the default node selectors for router / registry / logging / metrics / prometheus to target node-role.kubernetes.io/infra=true, and to indicate during install and upgrade the default value has changed and that playbook inventories should use the new role info.
Comment 3 Scott Dodson 2018-04-16 15:09:33 UTC 
Should be fixed in 3.10 master branch now.
Comment 4 Weihua Meng 2018-04-17 11:28:24 UTC 
Fixed.
