Hi thank you for this great tool.

I cannot make it work because i'm dumb :

i installed got on ansible controller
ansible [core 2.14.2]
pip install proxmoxer requests

on proxmox :
pip install proxmoxer requests

i checked if the api works :

curl -k -d 'username=root@pam' --data-urlencode 'password=MYPASSWORD https://192.168.10.30:8006/api2/json/access/ticket

it works :

pvedaemon[425432]: <root@pam> successful auth for user 'root@pam

when i'm trying to deploy playbook :

error_proxmoxer.txt

hosts: perseverance
gather_facts: no
vars:
inventory_hostname: "perseverance"
pve_api_user: "root@pam"
pve_api_password: "{{ vault_root_passwd }}"

lxc_network_bridge: "vmbr0"

  hostname: "{{ lxc_container_name }}"
  password: "{{ lxc_root_password }}"
  netif: "name=eth0,bridge={{ lxc_network_bridge }},ip={{ lxc_network_ip_address }}"
  cores: 2
  features:

  shell: >
  pvesh create /nodes/{{ inventory_hostname }}/lxc/{{ lxc_container_name }}/exec --tty -- /bin/bash -c "dnf -y install nextcloud"
- name: Start Nextcloud service in LXC container
  shell: >
  pvesh create /nodes/{{ inventory_hostname }}/lxc/{{ lxc_container_name }}/exec --tty -- /bin/bash -c "systemctl start nextcloud"

i got this error :

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: requests.exceptions.ConnectionError: HTTPSConnectionPool(host='%20perseverance%20', port=8006): Max retries exceeded with url: /api2/json/access/ticket (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f1b86ec8df0>: Failed to establish a new connection: [Errno -2] Name or service not known')) fatal: [192.168.10.30]: FAILED! => {"changed": false, "msg": "HTTPSConnectionPool(host='%20perseverance%20', port=8006): Max retries exceeded with url: /api2/json/access/ticket (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f1b86ec8df0>: Failed to establish a new connection: [Errno -2] Name or service not known'))"}

Do i need to change the https method to ssh ? if yes how ?

Thank you very much for any help.

Regards

As you can see in the error log it is trying to connect to '%20perseverance%20' instead of 'perseverance'. I don't know exactly where the extra spaces are getting added to your hostname, but that seems to be the reason the connection is not working.

If you are not able to figure it out, please ask on the ansible forums as this is not a proxmoxer issue.

You aren't dumb, you are just learning something new. It takes time and experimentation to get complex things like Ansible working correctly.
We were all where you were at once upon a time. Some people are ahead of the learning curve in some topics, and you are ahead of them in other topics.
