Provision Ubuntu 2004 on WSL2

Automating provisioning Ubuntu 20.04 with Ansible on WSL 2

Uses ansible, in a pipenv, in a WSL 2 Ubuntu instance to provision locally.

Intended to be re-runnable (idempotent) to maintain and update when required.

Getting Started

Prerequisites

1. Windows 10

2. WSL 2 (to enable, run the below commands in an elevated powershell prompt)

3. dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

4. dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

5. Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -NoRestart

6. wsl --set-default-version 2

7. wsl --shutdown

8. List available wsl distros wsl --list --online

9. Ubuntu 20.04 installed via cmd wsl --install -d Ubuntu-20.04

10. Generate an SSH key in your Ubuntu instance and add to Github

11. In PowerShell type ipconfig and note/copy the "Default Gateway" ip for "Wireless LAN adapter WiFi:"

12. Temp fix DNS echo "<default gateway ip>" > /etc/resolv.conf

13. Now you can clone this repo!

Fix known DNS issues with WSL2

1. ./scripts/fix_dns.sh -n "192.168.x.x" -h "a-host-name" (your home router IP)

Configure Python & pipenv (only need to do this once)

1. Install Make sudo apt install make
2. sudo apt-get update
3. make prep
4. make env

Clone and Run (the first time)

1. make shell
2. ansible-galaxy install -r requirements.yml
3. ansible-playbook playbook.yml -i inventory --ask-become-pass

Updating after adding new tasks or applications

1. cd provision-ubuntu2004-on-wsl2
2. make shell
3. make update

What is Installed?
