I've created new worker nodes that are dedicated to running Longhorn replicas. These nodes are tainted with the `node-role.kubernetes.io/longhorn` taint, so no regular pods will be scheduled there by default. Longhorn pods thus needs to be configured to tolerate that taint, and to be scheduled on nodes with the similarly-named label.
Persistent Storage Using Longhorn
Longhorn is a Kubernetes-native persistent storage system. It is quite complex, but installing it is fairly straightforward.
Installation
This is mostly based on the official Install with Kubectl instructions. I wanted to add node selectors to the user-deployed and system-managed components, to ensure that Longhorn only runs on x86_64 nodes, per the Node Selector instructions.
kubectl apply -f longhorn.yaml
Ingress
Expose the Longhorn UI outside the cluster:
kubectl apply -f longhorn-ingress.yaml
Authentication to the UI is handled by Authelia.
