Installing Longhorn on Talos Linux

I migrated my cluster so you don't have to.

I migrated my cluster from OpenEBS to Longhorn so you don’t have to. I saved ~70W in the process and my NUCs fans are no longer gasping for air. Here are the installation steps found in my video:

Install Dependencies

Talos Docs

brew install talhelper sops age

Generate Secrets

talhelper gensecret > talsecret.sops.yaml
mkdir -p "$HOME/Library/Application Support/sops/age"
age-keygen -o "$HOME/Library/Application Support/sops/age/keys.txt"

touch .sops.yaml

.sops.yaml:

---
creation_rules:
  - age: >-
      <public-key>

sops -e -i talsecret.sops.yaml

Generate Cluster Config

touch talconfig.yaml

talconfig.yaml

talhelper genconfig

talosctl apply-config -n <ip-address> --file <node-file-name>.yaml --insecure

Bootstrap Cluster

talosctl bootstrap --nodes x.x.x.x --endpoints x.x.x.x \                
  --talosconfig=talosconfig

Get Kubeconfig

talosctl kubeconfig  --nodes x.x.x.x --talosconfig=talosconfig

Create and Label ‘longhorn-system’ Namespace

kubectl create ns longhorn-system

kubectl label namespace longhorn-system pod-security.kubernetes.io/enforce=privileged

Install Longhorn

helm repo add longhorn https://charts.longhorn.io

helm repo update

helm install longhorn longhorn/longhorn --namespace longhorn-system --create-namespace --version 1.6.2

k port-forward service/longhorn-frontend 50483:80

Code from this installation can be found on GitHub.
