 # About
 
-The [Aspire Dashboard](https://aspire.dev/dashboard/standalone/) is a standalone viewer for logs, traces, and metrics from OpenTelemetry-enabled applications in any language. Source code is available in [microsoft/aspire](https://github.com/microsoft/aspire).
+This image contains the Aspire Dashboard.
 
-For preview builds, see the [nightly Aspire Dashboard image](https://mcr.microsoft.com/artifact/mar/aspire/nightly/dashboard/about).
+Watch [discussions](https://github.com/dotnet/dotnet-docker/discussions/categories/announcements) for Docker-related .NET announcements.
 
 # Usage
 
-Run the dashboard locally:
+The Aspire Dashboard is a browser-based app to view run-time information about your distributed application.
 
-```console
-docker run --rm -d --name aspire-dashboard -p 127.0.0.1:18888:18888 -p 127.0.0.1:4317:18889 -p 127.0.0.1:4318:18890 mcr.microsoft.com/aspire/dashboard:13
-```
+The dashboard shows:
 
-Open `http://localhost:18888`. To sign in, use the login URL or token printed in the container logs:
+* Resources that make up your app, such as .NET projects, executables and containers.
+* Live console logs of resources.
+* Live telemetry, such as structured logs, traces and metrics.
 
-```console
-docker logs aspire-dashboard
-```
+## Configuration
 
-This example keeps browser-token authentication enabled and binds the published ports to the host's loopback interface. Incoming OTLP telemetry is unauthenticated by default in standalone mode; the browser token does not secure telemetry ingestion. Only accept telemetry from trusted applications; configure HTTPS, authentication, and network controls before exposing the dashboard beyond your machine. See [dashboard security guidance](https://aspire.dev/dashboard/security-considerations/).
+The dashboard must be configured when it is started. The configuration is done via environment variables. The following environment variables are supported:
 
-## Send telemetry
+* `ASPNETCORE_URLS` specifies one or more HTTP endpoints through which the dashboard frontend is served. The frontend endpoint is used to view the dashboard in a browser. Defaults to `http://localhost:18888`.
+* `DOTNET_DASHBOARD_OTLP_ENDPOINT_URL` specifies the [OTLP/gRPC](https://opentelemetry.io/docs/specs/otlp/#otlpgrpc) endpoint. This endpoint hosts an OTLP service and receives telemetry using gRPC. When the dashboard is launched by the Aspire app host this address is secured with HTTPS. Securing the dashboard with HTTPS is recommended. Defaults to `http://localhost:18889`.
+* `DOTNET_DASHBOARD_OTLP_HTTP_ENDPOINT_URL` specifies the [OTLP/HTTP](https://opentelemetry.io/docs/specs/otlp/#otlphttp) endpoint. This endpoint hosts an OTLP service and receives telemetry using Protobuf over HTTP. Defaults to `http://localhost:18890`.
+* `ASPIRE_DASHBOARD_MCP_ENDPOINT_URL` specifies the Aspire MCP endpoint. When this value isn't specified then the MCP server is hosted with an `ASPNETCORE_URLS` endpoint. The MCP server can be disabled by configuring `Dashboard:Mcp:Disabled` to `true`. Defaults to `http://localhost:18891`.
+* `DOTNET_DASHBOARD_UNSECURED_ALLOW_ANONYMOUS` specifies the dashboard doesn't use authentication and accepts anonymous access. This setting is a shortcut to configuring `Dashboard:Frontend:AuthMode`, `Dashboard:Otlp:AuthMode` and `Dashboard:Mcp:AuthMode` to `Unsecured`.
+* `DOTNET_DASHBOARD_CONFIG_FILE_PATH` specifies the path for an optional JSON configuration file.
 
-Instrument your application with its language's OpenTelemetry SDK and configure an OTLP exporter with the matching protocol and endpoint. Starting the dashboard does not instrument your application automatically. For applications running on the host, use:
+### Frontend authentication
 
-* OTLP/gRPC: `http://localhost:4317` (mapped to container port `18889`).
-* OTLP/HTTP: `http://localhost:4318` (mapped to container port `18890`).
+The dashboard's frontend supports OpenID Connect (OIDC). Set `Dashboard__Frontend__AuthMode` to `OpenIdConnect`, then add the following configuration:
 
-For applications in other containers, use the dashboard container's name and port (`18889` or `18890`) on a shared Docker network, not their own `localhost`.
+* `Authentication__Schemes__OpenIdConnect__Authority` &mdash; URL to the identity provider (IdP)
+* `Authentication__Schemes__OpenIdConnect__ClientId` &mdash; Identity of the relying party (RP)
+* `Authentication__Schemes__OpenIdConnect__ClientSecret`&mdash; A secret that only the real RP would know
+* Other properties of [`OpenIdConnectOptions`](https://learn.microsoft.com/dotnet/api/microsoft.aspnetcore.builder.openidconnectoptions) specified in configuration container `Authentication__Schemes__OpenIdConnect__*`
 
-## Operational notes
+It may also be run unsecured. Set `Dashboard__Frontend__AuthMode` to `Unsecured`. The frontend endpoint will allow anonymous access. This setting is used during local development, but is not recommended if you attempt to host the dashboard in other settings.
 
-* Telemetry is stored in memory with configurable limits and is lost when the dashboard restarts. The dashboard is intended for development and short-term diagnostics, not durable telemetry storage.
-* Standalone mode displays telemetry without an AppHost. Resource listings and captured console logs require a configured [resource service](https://aspire.dev/dashboard/configuration/#resources).
+## OTLP authentication
 
-## Documentation and examples
+The OTLP endpoint can be secured with [client certificate](https://learn.microsoft.com/aspnet/core/security/authentication/certauth) or API key authentication.
 
-* [Run the standalone dashboard](https://aspire.dev/dashboard/standalone/).
-* [Python telemetry tutorial](https://aspire.dev/dashboard/standalone-for-python/).
-* [JavaScript and Node.js telemetry tutorial](https://aspire.dev/dashboard/standalone-for-nodejs/).
-* [Standalone dashboard sample (C#)](https://github.com/microsoft/aspire-samples/tree/main/samples/standalone-dashboard).
-* [Dashboard configuration reference](https://aspire.dev/dashboard/configuration/).
+For client certification authentication, set `Dashboard__Otlp__AuthMode` to `Certificate`.
+
+For API key authentication, set `Dashboard__Otlp__AuthMode` to `ApiKey`, then add the following configuration:
+
+* `Dashboard__Otlp__PrimaryApiKey` specifies the primary API key. (required, string)
+* `Dashboard__Otlp__SecondaryApiKey` specifies the secondary API key. (optional, string)
+
+It may also be run unsecured. Set `Dashboard__Otlp__AuthMode` to `Unsecured`. The OTLP endpoint will allow anonymous access. This setting is used during local development, but is not recommended if you attempt to host the dashboard in other settings.
+
+## Resources
+
+* `Dashboard__ResourceServiceClient__Url` specifies the gRPC endpoint to which the dashboard connects for its data. There's no default. If this variable is unspecified, the dashboard shows OTEL data but no resource list or console logs.
+
+The resource service client supports certificates. Set `Dashboard__ResourceServiceClient__AuthMode` to `Certificate`, then add the following configuration:
+
+* `Dashboard__ResourceServiceClient__ClientCertificate__Source` (required) one of:
+  * `File` to load the cert from a file path, configured with:
+    * `Dashboard__ResourceServiceClient__ClientCertificate__FilePath` (required, string)
+    * `Dashboard__ResourceServiceClient__ClientCertificate__Password` (optional, string)
+  * `KeyStore` to load the cert from a key store, configured with:
+    * `Dashboard__ResourceServiceClient__ClientCertificate__Subject` (required, string)
+    * `Dashboard__ResourceServiceClient__ClientCertificate__Store` (optional, [`StoreName`](https://learn.microsoft.com/dotnet/api/system.security.cryptography.x509certificates.storename), defaults to `My`)
+    * `Dashboard__ResourceServiceClient__ClientCertificate__Location` (optional, [`StoreLocation`](https://learn.microsoft.com/dotnet/api/system.security.cryptography.x509certificates.storelocation), defaults to `CurrentUser`)
+
+To opt-out of authentication, set `Dashboard__ResourceServiceClient__AuthMode` to `Unsecured`. This completely disables all security for the resource service client. This setting is used during local development, but is not recommended if you attempt to host the dashboard in other settings.
+
+### Telemetry Limits
+
+Telemetry is stored in-memory. To avoid excessive memory usage, the dashboard has limits on the count and size of stored telemetry. When a count limit is reached, new telemetry is added, and the oldest telemetry is removed. When a size limit is reached, data is truncated to the limit.
+
+* `Dashboard__TelemetryLimits__MaxLogCount` specifies the maximum number of log entries. Defaults to 10,000.
+* `Dashboard__TelemetryLimits__MaxTraceCount` specifies the maximum number of traces. Defaults to 10,000.
+* `Dashboard__TelemetryLimits__MaxMetricsCount` specifies the maximum number of metric data points. Defaults to 50,000.
+* `Dashboard__TelemetryLimits__MaxAttributeCount` specifies the maximum number of attributes on telemetry. Defaults to 128.
+* `Dashboard__TelemetryLimits__MaxAttributeLength` specifies the maximum length of attributes. Defaults to unlimited.
+* `Dashboard__TelemetryLimits__MaxSpanEventCount` specifies the maximum number of events on span attributes. Defaults to unlimited.
+
+Limits are per-resource. For example, a `MaxLogCount` value of 10,000 configures the dashboard to store up to 10,000 log entries per-resource.
+
+## Other
+
+* `Dashboard__ApplicationName` specifies the application name to be displayed in the UI. This applies only when no resource service URL is specified. When a resource service exists, the service specifies the application name.
