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

Add to your contaier config /etc/pve/lxc/XXX.conf:

lxc.apparmor.profile: unconfined
lxc.cgroup.devices.allow: a
lxc.cap.drop: 
lxc.mount.auto: proc:rw sys:rw

Netperf in homebrew is installed without demo mode by default, so we need to edit the recipe slightly, also demo mode fails to build under OS/X, requiring a tiny patch to netlib.c ( http://www.netperf.org/pipermail/netperf-talk/2013-December/001162.html ). The following recipe changes the URL to a prepatched version that I host and changes the configure line to enable demo mode.

`brew edit netperf`

```
class Netperf < Formula
  desc "Benchmarks performance of many different types of networking"

Profiling an application in Mac OS X

Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

The CPU pane shows how processes are affecting CPU (processor) activity:
