My Ubuntu server post-deploy script
Background
For most daily Linux use, I run Ubuntu 22.04 as a VM in Hyper-V on my Windows 10 laptop. I am sure others prefer a different way, but I like this setup. Win 10 is easiest to use in the corporate environment, and I have a Linux VM that feels local. It’s a server OS, and I can blow it away at any time.
Occasionally I will accidentally hose the machine and need to start from scratch. Inevitably I forget what and how I’ve installed packages, so I’m finally going to document a quick post-deploy script.

## First, Quick Create with Hyper-V often creates only a 12 GB disk.
# Shut down VM
# Use Hyper-V to extend disk to 128 GB. Instructions: https://linguist.is/2020/08/12/expand-ubuntu-disk-after-hyper-v-quick-create/
# Start up VM
sudo apt install cloud-guest-utils
sudo fdisk -l # this should show a DISK called /dev/sda and a DEVICE called /dev/sda1 with a size of 128 GB now.
sudo df -l # this should show a filesystem called /dev/sda1 but it won't be using all of the 128 GB yet
# Expand the sda1 partition into the free space
sudo growpart /dev/sda 1
# run resize2fs
sudo resize2fs /dev/sda1
sudo df -l ## this should now show the same filesystem, /dev/sda1, but now there is much more free space left.

I’m often told to use WSL2, but I like having a VM so that I can blow away/ roll back/ etc. In any case, I’ll update this script if/when I need.
