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:

printf 'Longhorn username: '
read longhorn_username
printf 'Longhorn password: '
read -s longhorn_password
printf '%s:%s\n' \
    "${longhorn_username}" \
    "$(openssl passwd -stdin -apr1 <<< "${longhorn_password}")" \
    > auth
kubectl create secret generic -n longhorn-system basic-auth --from-file auth
kubectl apply -f longhorn-ingress.yaml
