Hello there Ansible community,

I hope this is the right place to ask, if not please let me know.  
My goal is to fully automate the provising of containers, which includes the creation of a Proxmox container.

So I tried the following playbook task:

- name: ‘Create Proxmox container’  
proxmox: ‘api\_host=moon api\_user=root api\_password= vmid=200 hostname=ansible-test01 ip\_address=10.49.99.99 ostemplate=my-template.tgz password= state=present’

Whatever I try, the module tells me “authorization on proxmox cluster failed with exception: Couldn’t authenticate user”.  
Do I need to setup something special in Proxmox? On the Web GUI (Port 8006) the logins works without issues.

Any idea or pointers?  
Thanks a lot!

Florian

It's the correct place.

Ansible documentation and Proxmox api documentation say you should use username root@pam , have you tried that?
