Installing microk8s in an LXC container

I wanted to run Microk8s on a Proxmox 6 host inside of an LXC container. These are my notes from the journey.

1. Create a privileged LXC container through the Proxmox web interface

• Enable nesting and FUSE
  • In Proxmox UI, select container, then Options > Features > Check nesting and FUSE boxes

2. SSH into the Proxmox host and edit the container's config in /etc/pve/lxc/.conf
   • Add the following lines

• lxc.apparmor.profile: unconfined

Installing actions-runner-controller on microk8s running in LXC

This is a niche problem, but these steps worked for me. Proxmox 6.1-5 with microk8s v1.18.0 running in an LXC container. Tested with actions-runner-controller 0.4.1.

• Need to add --allow-privileged=true to /var/snap/microk8s/current/args/kube-apiserver
  • Then restart the API server: sudo systemctl restart snap.microk8s.daemon-apiserver.service
  • If this is a cluster of nodes, then this change needs to be applied on node hosting the control plane
• Enable "Create device nodes" feature for the container (Options > Features)
• Add to LXC container config: lxc.cgroup.devices.allow: a

How to build a bootable Arch-based thumb drive that can temporarily disable the Radeon GPU in a 2011 MacBook Pro.

I recently spent a few hours rescuing a faithful 2011-era MacBook Pro that had begun to suffer from the "Radeongate" graphics distortion problem. While it's possible to disable the Radeon GPU, the steps involve a lot of manual labor. Their automated solution produced an ISO that wouldn't boot for me, so I ended up building a custom ISO that only requires me to run one command after installing each macOS update. A non-technical family member can perform the fix, which is a big plus.

You'll need to buy RealMacMods' automated utility so that you can grab their script that does the heavy lifting. It's $10 at the time of this writing and is a nice way to support the
