Enabling Kafka on IIM

You can enable Kafka connection properties with SSL on an IIM setup.

Using Customization UI

Follow these steps to configure SSL-enabled Kafka:

Copy the truststore and keystore (jks) certificates to a directory on the file system where Sterling B2B Integrator instance is running.


For example:
/ibm/resources/certificates/common-ca/truststore.jks
/ibm/resources/certificates/kafka-consumer-1/kafka-consumer-1.jks

Update SSL connection related properties in the Customization UI and use /ibm/resources/ in the path.
Log in to the Customization UI as a user with APIUser permission and click customer_overrides. Navigate to the Property tab.

Create a property using the property key nosql_prop for kafka.properties file as mentioned below:

Property Key	Property Value
nosql_prop.ssl.truststore.location	`/ibm/resources/certificates/common-ca/truststore.jks`
nosql_prop.ssl.keystore.location	`/ibm/resources/certificates/kafka-consumer-1/kafka-consumer-1.jks`

Similarly, you can update other Kafka properties including the other SSL properties using the Customization UI.

Property Key	Property Value
nosql_prop.bootstrap.servers
nosql_prop.security.protocol	SSL
nosql_prop.ssl.truststore.password
nosql_prop.ssl.keystore.password
nosql_prop.ssl.key.password
nosql_prop.ssl.enabled.protocols	TLSv1.2,TLSv1.1,TLSv1
nosql_prop.ssl.truststore.type	JKS
nosql_prop.ssl.keystore.type	JKS

Follow these steps:

Update the properties in the kafka.properties.in file on the file system located in directory.
```
<Path_to_B2BI_Directory>/properties
```

Run the below command.
