Add Kafka TLS/mTLS certificate flags and secured-broker E2E test - #101
Merged
Conversation
Closes #70 by wiring ssl.ca/certificate/key CLI options through the consumer and adding SecureKafkaContainer plus SASL_SSL mTLS integration coverage.
Run the one-off apache/kafka cert container as root so openssl can write generated keys into the host temp directory mounted at /work.
Use the current uid:gid for the openssl docker run so generated client keys remain readable to the test process after bind-mount generation.

What is the motivation?
Production Kafka clusters often require TLS and mTLS with custom CAs; #70 called out missing certificate CLI support and we still have no integration test against a secured broker after #77 and #89.
What does this change do?
Adds
--ssl-*flags for the Kafka source, test harness support for a TLS/SASL broker, and documents TLS usage indocs/kafka.md.What is your testing strategy?
