Node Affinity

It specifies the node affinity policy configured for the volcano add-on.

• If it is set to Not configured, node affinity is disabled for the add-on pods.
• If it is set to Node Affinity, a node where the add-on pods will be deployed is specified. If you do not specify the node pool, the add-on will be randomly scheduled based on the default cluster scheduling policy.
• If it is set to Specified Node Pool Scheduling, a node pool where the add-on pods will be deployed is specified. If you do not specify the node pool, the add-on will be randomly scheduled based on the default cluster scheduling policy.
• If it is set to Custom Policies, you can take advantage of more flexible scheduling. You can enter labels of the nodes where the add-on is to be deployed. If you do not specify node labels, the add-on will be randomly scheduled based on the default cluster scheduling policy.
