Automation plays a key role in standardising and simplifying the process of building environments.

Continuing on my journey of automating my home lab setup, I found a very good resource that’s available for Proxmox users to automate the installation of various Linux containers and Virtual Machines. You can find them from user tteckster here https://tteck.github.io/Proxmox/

By using these scripts, we can save time, ensure consistency, and reduce the chances of human error during the environment build process.

Why Automate LXC and VM Builds?

Automation offers several notable benefits when it comes to building Linux containers and VMs:

Time and Effort Savings

Manually configuring and setting up containers or VMs can be a time-consuming and labor-intensive task.

By automating the build process using command line scripts, we can save significant time and effort.

Scripts eliminate the need to manually perform repetitive steps, allowing for faster deployment.

Consistency and Reproducibility

Maintaining consistency across multiple containers or VMs is vital in ensuring reliable application deployment.

Command line scripts enable us to define the exact configuration and settings required for each container or VM.

By automating the build process, every instance is built using the same steps, ensuring consistency and reproducibility across different environments.

Error Reduction

Manual configuration is prone to human error. Even a small mistake in the build process can lead to significant issues, affecting the stability and performance.

Automation minimises the chances of human error by executing a predefined set of instructions consistently.

Scripts can perform complex and error-prone tasks accurately, reducing the risk of misconfiguration or missteps.

Flexibility and Customisation

These command line scripts provide a flexible and customisable approach to building Linux containers and VMs.

These scripts often offer various options and parameters that allow us to tailor the build process according to their specific requirements.

We can choose different configurations, select specific software packages, and define resource allocation based on our application’s needs.

Introducing the Command Line Scripts

This brilliant website by tteckster provides a collection of command line scripts that enable the automation of Linux Container (LXC) and Virtual Machine (VM) builds on Proxmox.

These scripts enable us to create in an interactive manner, offering options for both basic and advanced configurations.

Basic Setup

The basic setup uses default settings, making it a convenient option for users who prefer a quick and straight forward setup.

To run the basic script for your specific machine, go through the list of options available and use the command in the Proxmox shell.

For example, to create a Linux Container for Cloudflared, we can use the following command:

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/cloudflared.sh)"

Or to create a MariaDB container, we can use the following command:

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/mariadb.sh)"

Advanced Setup

For more flexibility and customisation, the advanced setup feature of the scripts allows us to alter the default settings according to our needs.

This function utilises the whiptail command to present options in a dialogue box format, allowing us to modify the options available, such as increased memory, disk size and set options such as static IP addresses and DNS.

To run the advanced setup script, when prompted, choose the settings options when presented after running your chosen script.

After selecting your options, the script collects and verifies the input in order to generate the final configuration for the container or virtual machine.

Summary

Automating our Proxmox builds with command line scripts streamlines the deployment process, reduces manual effort, and ensures consistency and reproducibility.

By using the provided basic or advanced setup scripts from the website, we can easily build Linux Containers or Virtual Machines on Proxmox tailored to our specific needs in a repeatable manner.

Remember to visit https://tteck.github.io/Proxmox/ for more details and documentation on the available scripts.

There are also a number of other scripts available and can be found by searching on GitHub. For example, user roib20 has created Proxmox helper scripts for TrueNAS and CloudInit which can be found here https://github.com/roib20/proxmox-scripts
