Ansible sounds interesting (lemmy.ml)

Hi, got Proxmox installed. Now want to install some VMs but would like to use a simple setup rather than painfully going trough an install. I've read I could accomplish this via ansible. Are there ready playbooks you can hack? Presumably I would need to have Proxmox understand playbooks?

If you needs are simple, write a simple playbook using the proxmox ansible module https://docs.ansible.com/ansible/latest/collections/community/general/proxmox_kvm_module.html

Terraform/Opentofu provides more advanced stuff but then you have to worry about persistent state storage, the clunky DSL... used it when acsolutely needed, you can do 90% of this stuff with the proxmox ansible module.

If you need to make your playbook less verbose, move the logic to a role so that you can configure your VMs from a few lines in the playbook/host_vars. Mine looks like this (it's for libvirt and not proxmox, but the logic is the same)

# playbook.yml
- hosts: hypervisor.example.org
  roles:
    - libvirt

# host_vars/hypervisor.example.org.yml
libvirt_vms:
  - name: vm1.example.org
    xml_file: "{{ playbook_dir }}/data/libvirt/vm1.example.org.xml"
    state: running
    autostart: yes
  - name: vm2.example.org
    xml_file: "{{ playbook_dir }}/data/libvirt/vm2.example.org.xml"
    autostart: no
  - name: vm3.example.org
    xml_file: "{{ playbook_dir }}/data/libvirt/vm3.example.org.xml"
    autostart: no
  - name: vm4.example.org
    xml_file: "{{ playbook_dir }}/data/libvirt/vm4.example.org.xml"
    autostart: no
