|---|---|---|
| APP_ID | Your application | The id for your application, used for service discovery |
| APP_PORT | Your application | 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 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_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_METRICS_PORT | Your application | The HTTP Prometheus port to which Dapr sends its metrics information. With this variable, your application sends its application-specific metrics to have both Dapr metrics and application metrics together. See metrics-port for more information |
| DAPR_PROFILE_PORT | Your application | The profiling port through which Dapr lets you enable profiling and track possible CPU/memory/resource spikes in your application’s behavior. Enabled by --enable-profiling command in Dapr CLI for self-hosted or dapr.io/enable-profiling annotation in Dapr annotated pod. |
| DAPR_API_TOKEN | Dapr sidecar | The token used for Dapr API authentication for requests from the application. Enable API token authentication in Dapr. |
| NAMESPACE | Dapr sidecar | Used to specify a component’s namespace in self-hosted mode. |
| 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. |
| SSL_CERT_DIR | Dapr sidecar | Specifies the location where the public certificates for all the trusted certificate authorities (CA) are located. Not applicable when the sidecar is running as a process in self-hosted mode. |

| DAPR_HELM_REPO_USERNAME | A username for a private Helm chart | The username required to access the private Dapr Helm chart. If it can be accessed publicly, this env variable does not need to be set |
