Configuring Lima to use shared networking on macOS with socket_vmnet

Install https://github.com/lima-vm/socket_vmnet:

% git clone https://github.com/lima-vm/socket_vmnet.git
% cd socket_vmnet
% sudo make PREFIX=/opt/socket_vmnet install

Transcoding via Intel Quicksync in an Docker container under LXC on PVE

For Reasons™ I run Plex in a Docker container in LXC on Proxmox. Here's some configuration notes on making it work.

LXC container creation

It needs to be a privileged container
Needs to have nesting enabled

Once the container has been created, you need to manually add the following options to the container's configuration file (/etc/pve/lxc/<id>.conf):

RKE2 commands

Install

curl -sL https://get.rke2.io | sh
systemctl daemon-reload
systemctl start rke2-server

Configuring the Azure out-of-tree external Cloud Provider

RKE

A cluster configured using RKE needs to include the following section in cluster.yaml in order to specify that we want to use an external Cloud Provider:

K3s and Cilium with the Egress IP Gateway feature

This is a short guide to deploying a three-node Kubernetes cluster using K3s, including kube-vip to provide a HA control-plane and to manage LoadBalancer Service resources, and finally as Cilium as our CNI with the Egress Gateway feature enabled. We'll also heavily lean into Cilium's support for eBPF by doing away with kube-proxy entirely, but note that this does come with some limitations.

First, let's set some common options for K3s:

export K3S_VERSION="v1.22.4+k3s1"
export K3S_OPTIONS="--flannel-backend=none --no-flannel --disable-kube-proxy --disable-network-policy"

Cluster external iSCSI initiator to Longhorn volume target, via Cilium's CEW feature

With Cilium's Cluster External Workload feature it's possible to attach clients outside of the cluster to Longhorn volumes presented via iSCSI. This example uses RKE.

Cluster bring-up

I've created four virtual machines for my cluster - one as a controlplane / etcd host, and three workers:

cluster_name: cilium
