 | `--app-max-concurrency` | `--app-max-concurrency` | | `dapr.io/app-max-concurrency` | Limit the [concurrency of your application]({{< ref "control-concurrency.md#setting-app-max-concurrency" >}}). A valid value is any number larger than `0`|
 | `--metrics-port` | `--metrics-port` | | `dapr.io/metrics-port` | Sets the port for the sidecar metrics server. Default is `9090` |

-| `--placement-host-address` | `--placement-host-address` | | `dapr.io/placement-host-address` | Comma separated list of addresses for Dapr Actor Placement servers. When no annotation is set, the default value is set by the Sidecar Injector. When the annotation is set and the value is empty, the sidecar does not connect to Placement server. This can be used when there are no actors running in the sidecar. When the annotation is set and the value is not empty, the sidecar connects to the configured address. For example: `127.0.0.1:50057,127.0.0.1:50058` |
-| `--scheduler-host-address` | `--scheduler-host-address` | | `dapr.io/scheduler-host-address` | Comma separated list of addresses for Dapr Scheduler servers. When no annotation is set, the default value is set by the Sidecar Injector. When the annotation is set and the value is empty, the sidecar does not connect to Scheduler server. When the annotation is set and the value is not empty, the sidecar connects to the configured address. For example: `127.0.0.1:50055,127.0.0.1:50056` |

 | `--actors-service` | not supported | | not supported | Configuration for the service that offers actor placement information. The format is `<name>:<address>`. For example, setting this value to `placement:127.0.0.1:50057,127.0.0.1:50058` is an alternative to using the `--placement-host-address` flag. |
 | `--reminders-service` | not supported | | not supported | Configuration for the service that enables actor reminders. The format is `<name>[:<address>]`. Currently, the only supported value is `"default"` (which is also the default value), which uses the built-in reminders subsystem in the Dapr sidecar. |
 | `--profiling-port` | `--profiling-port` | | not supported | The port for the profile server (default `7777`) |
