Debezium SQLServer Connector failed SSL handshake

I have a running Kafka Connect instance and have submitted my connector with the following configuration at the bottom of this post. Kafka Connect itself seems to complete SSL handshake, but the sql-server-source-connector/status endpoint shows the SSL handshake failed…

Questions

  1. Kafka Connect completes the SSL handshake… but the worker does not. I’ve set the docker configs: CONNECT_SSL_*, CONNECT_CONSUMER_SSL_*, CONNECT_PRODUCER_SSL_and I've setdatabase.history.consumer.ssl.anddatabase.history.producer.ssl.*`in the connector request itself… What SSL configuration am I missing?

  2. The Kafka Connect topics seem to work… The Debezium docs seem to indicate I set database.server.name=connect_test and create topics for each table I want to ingest into kafka… So for my table, I’d create connect_test-TEST_Test_Table_Object. Are these the correct naming conventions for pre-created (aka, manually created) topics for the SQLServer connector with my config?

  3. connect-configs (1 partition)

  4. connect-offsets (3 partitions)

  5. connect-status (3 partitions)

  6. schema_changes-connect_test (3 partitions)

  7. connect_test-TEST_Test_Table_Object (3 partitions)
