      --kafka-group string                  Address of Kafka server to connect to.
                                            Environment variable: "KAFKA_GROUP" (default "group-e2e")
      --kafka-tls-ca-cert-file string       CA cert file Path.
                                            Environment variable: "KAFKA_TLS_CA_CERT_FILE"
      --kafka-tls-client-cert-file string   Client Cert File Path.
                                            Environment variable: "KAFKA_TLS_CLIENT_CERT_FILE"
      --kafka-tls-client-key-file string    Client key file Path.
                                            Environment variable: "KAFKA_TLS_CLIENT_KEY_FILE"
      --kafka-tls-enabled                   Whether or not to use TLS when connecting to the broker (defaults to false).

      --kafka-tls-insecure-skip-verify      Controls whether a client verifies the server's certificate chain and host name. If InsecureSkipVerify is true, TLS accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
                                            Environment variable: "KAFKA_TLS_INSECURE_SKIP_VERIFY"
