Ansible-Proxmox-inventory

About

Proxmox dynamic inventory for Ansible. Based on original plugin from Mathieu Gauthier-Lafaye

Changelog:

• Added option to ignore invalid SSL certificate (by @bmillemathias) PR
• Compatible with a Proxmox cluster (by @xezpeleta)
• Added group 'running' (by @xezpeleta)

Instructions

Download proxmox.py to /etc/ansible/ directory:

cd /etc/ansible
sudo wget https://github.com/xezpeleta/Ansible-Proxmox-inventory/raw/master/proxmox.py
sudo chmod +x proxmox.py

Let's test it:

python /etc/ansible/proxmox.py \
  --url=https://<your-proxmox-url>:8006/ \
  --username=<proxmox-username> \
  --password=<proxmox-password> \
  --trust-invalid-certs \
  --list --pretty

If you get a list with all the VM in your Proxmox cluster, everything is ok.

I suggest you to use environment variables to store Proxmox credentials:

# You also can do that using the file setenv.sh
# Run the command: "source setenv.sh"
export PROXMOX_URL=https://10.0.0.1:8006/
export PROXMOX_USERNAME=apiuser@pve
export PROXMOX_PASSWORD=apiuser1234
export PROXMOX_INVALID_CERT=False

You may also save your settings in a JSON file with the same name of the Python script, in its same folder (e.g.: if the downloaded script is /etc/ansible/proxmox.py, the configuration file will be /etc/ansible/proxmox.json):

{
    "url": "https://10.0.0.1:8006/",
    "username": "apiuser@pve",
    "password": "apiuser1234",
    "validateCert": false
}

So now you can check it again without credential parameters:

python /etc/ansible/proxmox.py --list --pretty

Once you get this working, you can include the dynamic inventory in your ansible commands:

# Ping: connect to all VM in Proxmox using root user
ansible -i /etc/ansible/proxmox.py all -m ping -u root

Tricks

If you prefer, you can limit the commands to the group "running":

# Run a playbook in every running VM in Proxmox
ansible-playbook -i /etc/ansible/proxmox.py --limit='running' playbook-example/playbook.yml

Thanks to Matt Harris, you can now use the Notes field in Proxmox to add a host to a group:

Added support for Proxmox VE 4.x Added support for using the Notes field of a VM to define groups and variables: A well-formatted JSON object in the Notes field will be added to the _meta section for that VM. In addition, the "groups" key of this JSON object may be used to specify group membership:

{ "groups": ["utility", "databases"], "a": false, "b": true }

For instance, you can use the following JSON code in a VM host:

{ "groups": ["windows"] }

So if you want to exclude Windows machines, you could do the following:

# Run a playbook in every running Linux machine in Proxmox
ansible-playbook -i /etc/ansible/proxmox.py --limit='running,!windows' playbook-example/playbook.yml

Examples

Show Linux distribution version for every VM in Proxmox cluster:

 ansible all -i /etc/ansible/proxmox.py --limit 'running,!windows' -m setup -u root -a 'filter=ansible_distribution_*'
