Ubuntu Development Environment Setup Script

Ubuntu Dev Setup Script

I tend to setup and teardown my dev environments quite frequently. So I have created this setup.sh script to automate setting up the dev environment with my preferences.

This script -

• Installs curl, git, net-tools, and tree.
• Installs build-essential package which installs gcc, g++ and some other libs.
• Installs the latest openjdk and maven.
• Installs python3 and some required libraries (I use them pretty often).
• Installs nodejs 12 globally. Then installs Node Version Manager and installs all LTS versions.
• Installs docker and docker-compose
• Installs zsh and oh-my-zsh and powerline fonts, and changes theme to agnoster.

The script has been tested on Ubuntu 20.04 (standalone and WSL2).

Prerequisites

• Make sure Windows 10 is updated to May 2020 Update (ver 2004)
• Open the Turn Windows features on or off utility. Enable -
  • Virtual Machine Platform
  • Windows Hypervisor Platform
  • Windows Subsystem for Linux
• Restart Windows to enable above features.
• Go to this link. Download and install WSL2 kernel.
• Open powershell and execute wsl --set-default-version 2 to set v2 as the default WSL2 version.
• Go to Microsoft Store and install a distribution of your choice (Ubuntu, Debian, etc). Optionally install Windows Terminal.

Visual Studio Code

Add this line in the settings.json file in VSCode

"terminal.integrated.fontFamily": "'Cascadia Mono PL'"

Making agnoster work in WSL (using Windows Terminal)

To make agnoster show all the glyphs properly in WSL, some additional steps are required.

1. Download and install the latest Cascadia Code.
2. In your profiles.json, change the fontFace property to Cascadia Code PL (or whichever variant you like).

So, your favorite WSL distro's settings will look something like

{
    "guid": "{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}",
    "name": "Ubuntu 20.04 LTS",
    "source": "Windows.Terminal.Wsl",
    "commandline": "wsl.exe -d Ubuntu-20.04",
    "fontFace": "Cascadia Code PL",
    "fontSize": 12,
}

NOTE: If you like to use the terminal provided by your favorite distro, then go to it's properties (right-click on title bar and click on properties), go to the Fonts tab, and select Cascadia Mono PL.

Extras

1. This issue in the agnoster-zsh-theme repo consists of some really cool zsh prompts.
2. atomcorp.github.io/themes/ has a bunch of really cool themes for Windows Terminal.
3. To open any folder/repo in VSCode, just go to the folder on terminal and execute code .. This will perform a one time setup where it installs the remote VSCode server in your distro.
4. To run linux GUI apps, install and run VcXsrv, then go to the Running Graphical Applications sub-section in the WSL Ubuntu Wiki and follow the steps there.
