How to use LXD (Linux containers) in a shell script to create VM when the cloud instance launches

by

You can use LXD (Linux containers) in a shell script to create a virtual machine (VM) when a cloud instance launches by following these steps:

  1. Install LXD:
sudo apt-get update
sudo apt-get install lxd
  1. Initialize LXD:
sudo lxd init
  1. Create a new container:
sudo lxc launch ubuntu:18.04 <container_name>
  1. Create a shell script to launch the container on instance start:
#!/bin/bash

lxc launch ubuntu:18.04 <container_name>

  1. Make the shell script executable:
chmod +x script.sh
  1. Add the shell script to the cloud instance’s start-up script:
sudo nano /etc/rc.local

Add the following line to the file:

/path/to/script.sh &
  1. Save and close the file.

The next time the cloud instance launches, the container will be automatically created using the shell script.

Note: These are general steps to create a VM using LXD in a shell script. Depending on your specific setup and requirements, you may need to make adjustments to the commands and configurations used. (https://perfumesample.com)
