Hi, I'm trying to automate the process of setting up kubernetes cluster for
training purposes.
The tasks to register the command for joining workers to a cluster is as
follows:
- name: get join token for workers
shell: kubeadm token create --print-join-command
register: token
I run the playbook in verbose mode and I can see that the command executes
properly, but the output can not be registered as there is an unexpected
exception:
"rc": 0,
"start": "2019-01-24 17:46:01.951209",
"stderr": "",
"stderr_lines": [],
"stdout": "kubeadm join 192.168.0.22:6443 --token
gh0qup.pxkqnbnr3w0gj4at --discovery-token-ca-cert-hash
sha256:b1d05a9a32918aa7ea84f73742b104856585a56e9cc31bbed6774d1a10ecaed0",
"stdout_lines": [
"kubeadm join 192.168.0.22:6443 --token gh0qup.pxkqnbnr3w0gj4at

sha256:b1d05a9a32918aa7ea84f73742b104856585a56e9cc31bbed6774d1a10ecaed0"
]
}
ERROR! Unexpected Exception, this is probably a bug: unhashable type: 'list'
the full traceback was:

I'm running the playbook on Centos7 minimal and the ansible version is:
ansible --version
ansible 2.5
Can someone help here? I was googling for a while but didn't find the
answer..
Regards,
Michal
