Portworx node labels
Portworx service and node configuration can be managed through Kubernetes node labels, allowing control over where Portworx is installed, and whether specific nodes should be designated as storage or metadata nodes. Below is a list of common Kubernetes node labels used for managing Portworx service behavior and node designation.
| Label | Description |
|---|---|
px/enabled=false | Prevents Portworx from being installed on a node. |
px/enabled=true | Allows Portworx to be installed on the node. This is the default behavior if no label is applied. |
px/enabled=remove | Removes Portworx from a node. After Portworx is removed, the label is converted to px/enabled=false. |
px/service=stop | Stops the Portworx service on a node. |
px/service=start | Starts the Portworx service on a node. |
px/service=restart | Restarts the Portworx service on a node. |
px/storage-node=true or false | Indicates whether a node is eligible to become a storage node. Note that this does not guarantee the node will become one. StorageCluster settings take precedence. |
px/metadata-node=true or false | Indicates whether a node is eligible to become a KVDB (metadata) node. It does not guarantee that the node will become one. |
portworx.io/node-type=storageless | For disaggregated installs, labels the node as part of the storageless node group. |
portworx.io/node-type=storage | For disaggregated installs, labels the node as part of the storage node group. |
