= Configuring node agents and node labels
|
|
|
|
[role="_abstract"]
|
|
The Data Protection Application (DPA) uses the `nodeSelector` field to select which nodes can run the node agent. The `nodeSelector` field is the recommended form of node selection constraint.
|
|
|
|
.Procedure
|
|
|
|
. Run the node agent on any node that you choose by adding a custom label:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc label node/<node_name> node-role.kubernetes.io/nodeAgent=""
|
|
----
|
|
+
|
|
[NOTE]
|
|
====
|
|
Any label specified must match the labels on each node.
|
|
====
|
|
|
|
. Use the same custom label in the `DPA.spec.configuration.nodeAgent.podConfig.nodeSelector` field, which you used for labeling nodes:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
configuration:
|
|
nodeAgent:
|
|
enable: true
|
|
podConfig:
|
|
nodeSelector:
|
|
node-role.kubernetes.io/nodeAgent: ""
|
|
----
|
|
+
|
|
The following example is an anti-pattern of `nodeSelector` and does not work unless both labels, `node-role.kubernetes.io/infra: ""` and `node-role.kubernetes.io/worker: ""`, are on the node:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
configuration:
|
|
nodeAgent:
|
|
enable: true
|
|
podConfig:
|
|
nodeSelector:
|
|
node-role.kubernetes.io/infra: ""
|
|
node-role.kubernetes.io/worker: ""
|
