Hi all,
I am trying to write a python script to run kuberspray
<https://github.com/kubernetes-sigs/kubespray>'s ansible-playbook.
Basically, when using kubespray, all I need to do is get into kubespray's
folder and type command.
ansible-playbook -i inventory/mycluster/hosts.ini cluster.yml
Tell ansible-playbook where the inventory and playbook file is.
And ansible will include all the group_vars in
the inventory/mycluster/group_vars automatically.
'kubespray/inventory/mycluster/group_vars'
Here is my python script trying to call ansible-playbook to do the same
thing.
Based on some internet examples and the document from ansible webpage.
But when I run this script, it shows some error about the undefined
variables.
How to import all the variables inside the group_vars?
