Hi,

Thanks for the detailed explanation.

I got the below error while deploying the cluster. could you please help

[root@kmaster kubespray]# ansible-playbook -u centos -b -i inventory/mycluster/hosts.ini cluster.yml

[WARNING]: Invalid characters were found in group names but not replaced, use -vvvv to see details

ERROR! 'delegate_to' is not a valid attribute for a TaskInclude

The error appears to be in '/root/kubespray/roles/network_plugin/calico/tasks/main.yml': line 6, column 3, but may

be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- include_tasks: upgrade.yml

^ here
