Parameter	Type	Default	Description
`controller.replicas`	integer	`3`	Number of controller pod replicas.
`controller.podAnnotations`	object	`{}`	Annotations to apply to controller pods.
`controller.podLabels`	object	`{}`	Labels to apply to controller pods.
`controller.hostNetwork`	boolean	`false`	Enable host network namespace for controller pods.

Node server configuration

The node server DaemonSet runs on each node to manage local drives.

Parameter	Type	Default	Description
`nodeserver.podAnnotations`	object	`{}`	Annotations to apply to node server pods.
`nodeserver.podLabels`	object	`{}`	Labels to apply to node server pods.
`nodeserver.hostNetwork`	boolean	`false`	Enable host network namespace for node server pods.
`nodeserver.nodeSelector`	object	`{}`	Node selector constraints for scheduling node server pods.
`nodeserver.tolerations`	array	`[]`	Tolerations for scheduling node server pods on tainted nodes.
`nodeserver.seccompLocalhostProfile`	string	`""`	Seccomp localhost profile path for container security.

Examples

Limit nodes with node selector

Restrict DirectPV to specific nodes using labels:

nodeserver:
  nodeSelector:
    aistor.min.io/pool-id: "1"

Allow scheduling on control plane nodes

Add tolerations to schedule on tainted nodes:

nodeserver:
  tolerations:
    - key: "node-role.kubernetes.io/control-plane"
      operator: "Exists"
      effect: "NoSchedule"

Configure seccomp profile

Enable seccomp security profile:

nodeserver:
  seccompLocalhostProfile: "profiles/seccomp.json"

You must load the seccomp profile on nodes before enabling this option. See the security profiles documentation.

Use private registry

Configure image pull secrets for air-gapped environments:

images:
  pullSecrets:
    - name: my-registry-secret
  directpv: my-registry.example.com/minio/directpv:v5.1.0
  livenessprobe: my-registry.example.com/minio/livenessprobe:v2.17.0-0
  csiNodeDriverRegistrar: my-registry.example.com/minio/csi-node-driver-registrar:v2.15.0-0
  csiProvisioner: my-registry.example.com/minio/csi-provisioner:v6.0.0-0
  csiResizer: my-registry.example.com/minio/csi-resizer:v2.0.0-0

Complete custom values file

Example aistor-volumemanager-values.yaml with common customizations:

annotations:
  environment: production

labels:
  team: storage

nodeserver:
  nodeSelector:
    node-role.kubernetes.io/storage: "true"
  tolerations:
    - key: "dedicated"
      operator: "Equal"
      value: "storage"
      effect: "NoSchedule"
  seccompLocalhostProfile: "directpv-seccomp.json"

controller:
  replicas: 3
  podAnnotations:
    prometheus.io/scrape: "true"

Install using the custom values:

helm install directpv minio/aistor-volumemanager -f aistor-volumemanager-values.yaml
