MT_SCHEDULER

MT_SCHEDULER=quartz

If specified, the name of the queue for the message scheduler endpoint. The name will automatically be converted to the appropriate address for the transport.

If not specified, the transport-specific delayed message delivery mechanism is configured. For RabbitMQ, this configures the delayed exchange message scheduler via the .UseDelayedExchangeMessageScheduler() method.

To configure the connection string for the masstransit/quartz preconfigured Docker image, MT_Quartz__ConnectionString should be set to the connection string for the Quartz database.

MT_PROMETHEUS

MT_PROMETHEUS=serviceName

If present, Prometheus metrics are enabled and exported using the specified service name. The metrics can be scraped from the service at host:80/metrics.

MT_APP

MT_APP=/app

By default, the MT_APP variable is set to /app, which is the default docker path for .NET applications that are using the platform. There typically is no reason to change this value, but it is documented for completeness.
