All connection information required by your triggers and bindings should be maintained in application settings and not in the binding definitions in your code. This is true for credentials, which should never be stored in your code.
Important
Credential settings must reference an application setting. Don't hard-code credentials in your code or configuration files. When running locally, use the local.settings.json file for your credentials, and don't publish the local.settings.json file.
When connecting to a managed Kafka cluster provided by Confluent in Azure, make sure that the following authentication credentials for your Confluent Cloud environment are set in your trigger or binding:
| Setting | Recommended value | Description |
|---|---|---|
| BrokerList | BootstrapServer |
App setting named BootstrapServer contains the value of bootstrap server found in Confluent Cloud settings page. The value resembles xyz-xyzxzy.westeurope.azure.confluent.cloud:9092. |
| Username | ConfluentCloudUsername |
App setting named ConfluentCloudUsername contains the API access key from the Confluent Cloud web site. |
| Password | ConfluentCloudPassword |
App setting named ConfluentCloudPassword contains the API secret obtained from the Confluent Cloud web site. |
When connecting to Event Hubs, make sure that the following authentication credentials for your Event Hubs instance are set in your trigger or binding:
| Setting | Recommended value | Description |
|---|---|---|
| BrokerList | BootstrapServer |
App setting named BootstrapServer contains the fully qualified domain name of your Event Hubs instance. The value resembles <MY_NAMESPACE_NAME>.servicebus.windows.net:9093. |
| Username | $ConnectionString |
Actual value is obtained from the connection string. |
| Password | %EventHubsConnectionString% |
App setting named EventHubsConnectionString contains the connection string for your Event Hubs namespace. To learn more, see Get an Event Hubs connection string. |
The string values you use for these settings must be present as application settings in Azure or in the Values collection in the local.settings.json file during local development.
You should also set the Protocol, AuthenticationMode, and SslCaLocation in your binding definitions.
