Before you build clusters
Verify that all inventory files are updated.
If the cluster requires more than 10 kubernetes nodes, use a docker enterprise account to avoid docker pull limits.
Verify that all nodes are assigned a group. Use the inventory as a reference. The inventory file is case-sensitive. Follow the format provided in the sample file link.
If NFS or BeeGFS are required on the cluster, run
storage.yml
.
Note
The inventory file accepts both IPs and FQDNs as long as they can be resolved by DNS.
In a multi-node setup, IP’s cannot be listed as a control plane and a cluster node. That is, don’t include the kube_control_plane IP address in the compute group. In a single node setup, the compute node and the kube_control_plane must be the same.
Users should also ensure that all repos are available on the cluster nodes running RHEL.
