Gitpod Self-hosted + RKE2

My journey so far making Gitpod play nice with RKE2, and other notes. This is what I've got working in the very small amount of time I have to work on this. Hopefully this helps as a starting point for a more robust and supported Gitpod+RKE2 solution.

This only documents some of the specific configurations, not everything needed to create the cluster itself (e.g., VPC; DNS).

I will update as time permits along the way!

Ubuntu 24.04

From the comments: "These exact instructions are not working on Ubuntu 24.04. Ubuntu has changed the naming of ZFS partitions, partition 2 and 3 are switched around, and the boot/efi folder is now different."

I don't have my dual-disk test system any longer, and so can't adjust these steps myself.

Overview

Ubuntu Desktop 20.04 supports a single ZFS boot drive out of the box. I wanted a ZFS mirror, without going through an entirely manual setup of Ubuntu as described by OpenZFS in their instructions for Ubuntu 20.04 and instructions for Ubuntu 22.04

Simple guide for fulldisk encryption with Proxmox and ZFS native encryption

Install normally using the installer, after the setup reboot into recovery mode (from the USB stick). Make sure to install in UEFI mode (you need systemd-boot).

If the USB stick is not working for you, because of the old Kernel version (2.6.x), you can also use an Ubuntu 19.10 / 20.04 boot stick. ZFS suport is enabled there out of the box.

Steps:

Setup a Node.js project with Typescript, ESLint, Prettier, Husky

Starting a personal node project could be easy; starting a team node project could be challenging.

I am a developer currently working in SEEK Australia.

In my experience, common mistakes developer make when starting a projects are:

No Linting

How to disable cloud-init in Ubuntu

Prevent start

Create an empty file to prevent the service from starting
```
  sudo touch /etc/cloud/cloud-init.disabled
```

Uninstall

Do not use forEach with async-await

TLDR: Use for...of instead of forEach() in asynchronous code.

For legacy browsers, use for...i or [].reduce()

To execute the promises in parallel, use Promise.all([].map(...))

Ubuntu Grub Boot Kernel

Boot a specific installed Ubuntu kernel using grub-reboot and grub-set-default.

This allows you to pick what kernel you want to boot on next reboot, or set the default, without having to know much about how grub works or editing config files.

Usage

  Usage: boot-kernel [options] [kernel]

call grub-reboot or grub-set-default to boot the provided kernel.
