Note: port names must be unique and no more than 15 characters long. | +| service.sessionAffinity | string | `"None"` | The session affinity for the service. Valid values are: None, ClientIP. ClientIP enables sticky sessions based on the client's IP address. This is generally beneficial to Polaris deployments, but some testing may be required in order to make sure that the load is distributed evenly among the pods. Also, this setting affects only internal clients, not external ones. If Ingress is enabled, it is recommended to set sessionAffinity to None. | +| service.type | string | `"ClusterIP"` | The type of service to create. | +| serviceAccount.annotations | object | `{}` | Annotations to add to the service account. | +| serviceAccount.create | bool | `true` | Specifies whether a service account should be created. | +| serviceAccount.name | string | `""` | The name of the service account to use.
