RE: Issue by installing OKD OpenShift 3.11



Hi Andrej,

Thanks for this useful information.
I've changed my config and restart the playbook. Unfortunately, the problem still occurs but I think that the issue is elsewhere, as indicated in the logs.

Best regards, J

Hi,

if you have master and etcd colocated on the same node, you should use 'node-config-master-infra' node group instead of 'node-config-master'.

Check the last 2 paragraphs of [1].
