I am confusing about the conent produced by kubespray-aws-inventory.py and host.ini. They looks the same.

I copyed the script into my inventory directory ./inventory/aws-k8s/. Then the command:
ansible-playbook -b -i inventory/aws-k8s/kubespray-aws-inventory.py cluster.yml .

Same error i met with you.

For troubleshooting now. I'm cutting option "kubespray-aws-inventory.py" and let's deploy as on-prem host with set "cloud provider: aws". This way i found a lot of bug can fix and kubernetes work like usual
