Description Weihua Meng 2018-04-13 10:05:23 UTC 
Description of problem:
Pods pending due to node does not have label "node-role.kubernetes.io/compute=true" in all-in-one cluster

Version-Release number of the following components:
openshift-ansible-3.10.0-0.21.0.git.0.0b1d180.el7.noarch.rpm

How reproducible:
Always

Steps to Reproduce:
1. deploy OCP all-in-one cluster
2. check pods status and node labels

Actual results:
pod in pending status due to 
"Node-Selectors:  node-role.kubernetes.io/compute=true"

This is default in master-config
projectConfig:
  defaultNodeSelector: node-role.kubernetes.io/compute=true

# oc get node --show-labels
NAME                       STATUS    ROLES     AGE       VERSION             LABELS
qe-wmengrpm310a1-merrn-1   Ready     master    4h        v1.10.0+b81c8f8   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/instance-type=n1-highmem-4,beta.kubernetes.io/os=linux,failure-domain.beta.kubernetes.io/region=us-central1,failure-domain.beta.kubernetes.io/zone=us-central1-a,kubernetes.io/hostname=qe-wmengrpm310a1-merrn-1,node-role.kubernetes.io/master=true,registry=enabled,role=node,router=enabled

Expected results:
at least one node should have the label match default node selector.
node should have node-role.kubernetes.io/compute=true label in all-in-one cluster.
Comment 1 Vadim Rutkovsky 2018-04-13 11:34:07 UTC 
Created https://github.com/openshift/openshift-ansible/pull/7945 to fix this
Comment 2 Jan Pazdziora 2018-04-13 13:05:34 UTC 
With Origin, we see the problem with 3.9 as well: https://github.com/openshift/openshift-ansible/issues/7833. For OCP, is this isolated to 3.10 only?
