Test Openshift Container Platform (OCP) flow matrix
Environment
- Red Hat Openshift Container Platform 3.11
- Red Hat Enterprise Linux >= 7
Issue
Strange behaviour on OCP 3.11 or broken communication between nodes.
Sample:
couldn't get resource list for servicecatalog.k8s.io/v1beta1: the server is currently unable to handle the request
couldn't get resource list for metrics.k8s.io/v1beta1: the server is currently unable to handle the request
Resolution
The underlying network and firewalls can be tested by using this Ansible playbook : https://github.com/simbelmas/ocp-flow-tester
Different levels of checks can be achieved:
- disabling firewall, underlying network is tested
- keeping firewall, cluster configuration and underlying network is tested
Root Cause
The underlying network does not meet prerequisites expectations or cluster configuration is wrong.
