I am new to OpenShift and trying to deploy IBM Db2 on OCP. following https://github.com/IBM/charts/tree/master/stable/ibm-db2 but as soon as I am deploying the pods, the pods are forever in pending state and show the error as:
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Warning FailedScheduling 8s (x65 over 95m) default-scheduler 0/5 nodes are available: 5 node(s) didn't match node selector.
even if I mark dedicated as false(parameter mentioned in the github link under Configuration section of README.md) or if I label the nodes(3 master 2 worker) as icp4data=icp4data I get the same error.
