Kafka Connect

This page provides examples for defining a connection to Kafka Connect Clusters.

Simple configuration, with JMX metrics

The URLs (workers) should always have a scheme defined (http:// or https://).

This example uses an optional AES-256 key. The key decodes values encoded with AES-256 to enable passing encrypted values to connectors. It is only needed if your cluster uses AES-256 Decryption plugin.

kafkaConnect:
  - name: my-connect-cluster-name
    version: 1    
    tags: ["tag1"]
    configuration:
      workers:
        value:
          - http://my-kc.worker1:8083
          - http://my-kc.worker2:8083

Basic authentication

For Basic Authentication, define username and password properties.

kafkaConnect:
  - name: my-connect-cluster-name
    tags: ["tag1"]
    version: 1      
    configuration:
      workers:
        value:
          - http://my-kc.worker1:8083
          - http://my-kc.worker2:8083    
      username: 
        value: my-username
      password: 
        value: my-password

TLS with custom truststore

A custom truststore is needed when the Kafka Connect workers are served over TLS (encryption-in-transit) and their certificates are not signed by a trusted CA.

kafkaConnect:
  - name: my-connect-cluster-name
    tags: ["tag1"]
    version: 1      
    configuration:
      workers:
        value:
          - http://my-kc.worker1:8083
          - http://my-kc.worker2:8083    
      sslTruststore:
        file: /path/to/my/truststore.jks
      sslTruststorePassword: 
        value: myPassword

TLS with client authentication

A custom truststore might be necessary too (see above).

kafkaConnect:
  name: my-connect-cluster-name
  tags: ["tag1"]
  version: 1    
  configuration:
    workers:
      value:
        - http://my-kc.worker1:8083
        - http://my-kc.worker2:8083    
   sslKeystore:
      file: /path/to/my/keystore.jks
    sslKeystorePassword: 
      value: myPassword
