Doc Text: |
Cause: A value of 16000 nodes was set when calculating the end of DHCP allocation pool when provisioning the nodes subnet.
Consequence: deploying OpenShift on OpenStack platform with a machine CIDR smaller than /18 resulted in an error.
Fix: stop hardcoding the number of nodes and instead dynamically calculate the end of DHCP allocation pool.
Result: it is now possible to deploy OpenShift on OpenStack with machine CIDR of any length, provided it is large enough to for all needed nodes.
