k8s-starter-pack/apps/longhorn.yaml

# Longhorn — this repo's pre-installed storage layer. Same pattern as
# apps/metallb.yaml: an Application pointing at a Helm chart
# (apps/longhorn/) that pulls in the official upstream chart. Once this
# syncs, any app in this cluster can request persistent storage (a
# PersistentVolumeClaim) and actually get real, replicated storage backed
# by the dedicated disk each worker prepared with
# talos/patch-longhorn.yaml — see docs/06-longhorn.md.
#
# Longhorn needs privileged Pods (it manages block devices directly) and
# the `open-iscsi`/`util-linux-tools` Talos system extensions baked into
# your node image — both covered in docs/01-prerequisites.md and
# docs/02-talos-bootstrap.md. Skipping either means Longhorn's Pods will
# sit unhealthy no matter how correctly this Application syncs.
