 | APP_PORT             | Dapr sidecar | The port your application is listening on  |
 | APP_API_TOKEN        | Your application | The token used by the application to authenticate requests from Dapr API. Read [authenticate requests from Dapr using token authentication]({{< ref app-api-token >}}) for more information. |
 | DAPR_HTTP_PORT       | Your application | The HTTP port that the Dapr sidecar is listening on. Your application should use this variable to connect to Dapr sidecar instead of hardcoding the port value. Set by the Dapr CLI run command for self-hosted or injected by the `dapr-sidecar-injector` into all the containers in the pod.                                   |
-| DAPR_HTTP_ENDPOINT   | Your application | The HTTP endpoint that the Dapr sidecar is listening on. Your application should use this variable to change the endpoint used to connect to the Dapr sidecar instead of hardcoding an alternative hostname. It is expected that this value minimally include the schema and hostname.|
+| DAPR_HTTP_ENDPOINT   | Your application | The HTTP endpoint that the Dapr sidecar is listening on. Your application should use this variable to change the endpoint used to connect to the Dapr sidecar instead of hardcoding an alternative hostname. It is expected that this value minimally include the schema and hostname: `https://dapr.io` would indicate an `https` schema, a hostname of `dapr.io` and the implied (via the `https` scheme) port of `443` |
 | DAPR_GRPC_PORT       | Your application | The gRPC port that the Dapr sidecar is listening on. Your application should use this variable to connect to Dapr sidecar instead of hardcoding the port value. Set by the Dapr CLI run command for self-hosted or injected by the `dapr-sidecar-injector` into all the containers in the pod.                                   |

 | DAPR_API_TOKEN  | Dapr sidecar     | The token used for Dapr API authentication for requests from the application. [Enable API token authentication in Dapr]({{< ref api-token >}}). |
 | NAMESPACE | Dapr sidecar | Used to specify a component's [namespace in self-hosted mode]({{< ref component-scopes >}}). |
 | DAPR_DEFAULT_IMAGE_REGISTRY | Dapr CLI | In self-hosted mode, it is used to specify the default container registry to pull images from. When its value is set to `GHCR` or `ghcr`, it pulls the required images from Github container registry. To default to Docker hub, unset this environment variable. |
