+ ### Docker Compose File (`ubuntu.yml`)
+
+ Once the snippets has been added to the local location you can cd to the /var/lib/snippets directory
+
+ ```code
+ cd /var/lib/vz/snippets/
+ ```
+ Next using nano create the ubuntu.yaml file
+
+ ```code
+ nano ubuntu.yaml
+ ```
+
+ copy and paste the following code
+
+ ```yaml
+ #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

+ ```
+ Next need to create the bash script to create the template
+
+ ```code
+ nano create-template.sh
+ ```
+
+ ```bash
+ #! /bin/bash
+
+ VMID=<Your ID you would Like to use>
+ STORAGE=<Your storage location>
+ USER=<your username>
