Configuring

PVE server

Install utils

apt install pip

pip3 install proxmoxer

sudo apt install libguestfs-tools -y

Create and move to dir

mkdir /root/cloud-init

cd /root/cloud-init

Download Almalinux 8 cloud-init image

wget https://repo.almalinux.org/almalinux/8/cloud/x86_64/images/AlmaLinux-8-GenericCloud-latest.x86_64.qcow2 -O almalinux8.qcow2

Set nano as default editor

EDITOR=nano; export EDITOR

Edit configurations in the al8-ci image

virt-edit -a almalinux8.qcow2 /etc/cloud/cloud.cfg

virt-customize -a almalinux8.qcow2 --timezone "Europe/Moscow"

virt-customize -a almalinux8.qcow2 --update

virt-customize -a almalinux8.qcow2 --install qemu-guest-agent,nano,wget

virt-customize -a almalinux8.qcow2 --run-command 'sudo systemctl enable qemu-guest-agent'

Set root password

read -sp "Password for root: " pwd && virt-customize -a almalinux8.qcow2 --root-password password:$pwd

   PassWord

Create VM for future template    

qm create 1001 --name "al8-ci-tmplt-01" --memory 1024 --cores 1 --net0 virtio,bridge=vmbr0

Import disk

qm importdisk 1001 almalinux8.qcow2 ceph-rbd01

Add imported disk

qm set 1001 --scsihw virtio-scsi-pci --scsi0 ceph-rbd01:vm-1001-disk-0

Set boot disk

qm set 1001 --boot c --bootdisk scsi0

Add cloud-init image into the VM

qm set 1001 --ide2 ceph-rbd01:cloudinit

Set agent

qm set 1001 --agent 1

Convert VM to template

qm template 1001

Ansible server

dnf install -y ansible

Create root Ansible project dir

mkdir ./pve_create_vm

cd ./pve_create_vm

Add necessary project files

Edit vars

nano inventory/hosts.ini

nano vars.ini

Run VM creation

ansible-playbook vm_create.yml

After that you will get the VM with corresponding parameters
