Piraeus Operator

The Piraeus Operator manages LINSTOR clusters in Kubernetes.

All components of the LINSTOR software stack can be managed by the operator:

• DRBD
• LINSTOR
• LINSTOR CSI driver
• LINSTOR High-Availability Controller

Legacy Operator

The previous version of Piraeus Operator is still available here.

If you are currently using Piraeus Operator v1, please continue to use it. It will be maintained, receiving updates to fix issues or new software versions until a stable upgrade path to v2 is available.

Usage

To deploy Piraeus Operator v2 from this repository, simply run:

$ kubectl apply --server-side -k "https://github.com/piraeusdatastore/piraeus-operator//config/default?ref=v2.5.0"
# Verify the operator is running:
$ kubectl wait pod --for=condition=Ready -n piraeus-datastore -l app.kubernetes.io/component=piraeus-operator
pod/piraeus-operator-controller-manager-dd898f48c-bhbtv condition met

Now you can create a basic storage cluster by applying the LinstorCluster resource.

$ kubectl apply -f - <<EOF
apiVersion: piraeus.io/v1
kind: LinstorCluster
metadata:
  name: linstorcluster
spec: {}
EOF
