thanks,I try it :
shell: kubeadm join --control-plane {{ groups['master'][0] }}:6443 --token
{{ hostvars[groups['master']|first]['kubeadm_token'].stdout }}
--discovery-token-ca-cert-hash sha256:{{
hostvars[groups['master']|first]['kubeadm_hash'].stdout }}
but the ansible-playbook command is sei
You could try something
hostvars[groups['master']|first] instead of hostvars['master'] in my
proposition to see it that works...not sure
Use a debug module could help

I'm wrong it's not hostvars['master'], because master is not the

use it for another (47.108.213.148).
I'm have no experience with kubeadm but I think your logic wrt host
