General kafka configuration

Configuring access to Existing Kafka cluster​

Properties​

Here, you should provide Kafka properties required by:

to connect to your Kafka cluster, and by

to connect to Schema Registry server.

Configuration should be provided in JSON format.

Example configuration:

{
  "bootstrap.servers": "kafka.some.domain-1:9092,kafka.some.domain-2:9092,kafka.some.domain-3:9092",
  "security.protocol": "SASL_SSL",
  "sasl.jaas.config": "org.apache.kafka.common.security.plain.PlainLoginModule required username = \"username\" password=\"password\";",
  "sasl.mechanism": "PLAIN",
  "ssl.truststore.type": "PEM",
  "ssl.truststore.location": "/certs/client.truststore",
  
  "schema.registry.url": "https://some.schema.registry.host:8080",
  "basic.auth.credentials.source": "USER_INFO",
  "basic.auth.user.info": "usernameToSR:passwordToSR"
}

Keystore​

If your Kafka cluster is configured to use TLS/SSL encryption and therefore requires a keystore to connect, here you can paste it in PEM format. Please remember to include both key and certificates (see e.g. this blog for the details)

At runtime keystore file will be available in /certs/client.keystore location, so in Properties config, set it at key ssl.keystore.location.

If your Kafka configuration does not require keystore leave this field empty.

Truststore​

If your Kafka cluster requires a truststore to connect, here you can provide the truststore file in PEM format.

At runtime the truststore file will be available in /certs/client.truststore location, so in Properties config, set it at key ssl.truststore.location.

If your Kafka configuration does not require truststore leave this field empty.
