Create Template
Create a template using Ubuntu Cloud Image and customization script
Customization script (ubuntu.yml)
Once the snippets has been added to the local location you can cd to the /var/lib/snippets directory
cd /var/lib/vz/snippets/
Next using nano create the ubuntu.yaml file
nano ubuntu.yaml
copy and paste the following code
#cloud-config runcmd: - apt update - apt install -y qemu-guest-agent - systemctl enable ssh - apt install -y apt-transport-https ca-certificates curl software-properties-common - curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg - echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu noble stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null - apt update - apt-cache policy docker-ce - apt install -y docker-ce - systemctl status docker - usermod -aG docker mbtech - echo "mbtech ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers - mkdir -p ~/.docker/cli-plugins/ - curl -SL https://github.com/docker/compose/releases/download/v2.36.0/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose - chmod +x ~/.docker/cli-plugins/docker-compose # Taken from https://forum.proxmox.com/threads/combining-custom-cloud-init-with-auto-generated.59008/page-3#post-428772
Next need to create the bash script to create the template
cd ~
nano create-template.sh

Reminder you need to change the variables:
VMID=<Your ID you would Like to use> STORAGE=<Your storage location> USER=<your username>
