[release-5.7] TLS configuration for multiple Kafka brokers is not created in Vector

Prior to this update, TLS configuration was not generated for the vector log collector forwarding logs to a Kafka destination, if the destination Kafka broker URLs were specified only as the kafka/brokers list, without specifying the 'url' field of the output. After this update, TLS configuration is generated in the above situation.

1) Deploy CLO 5.6.4 version. 2) Create a CR resource using Vector as collector. 3) Create a secret and a CLF instance with multiple Kafka brokers: spec: outputs: - kafka: brokers: - tls: //xxxx1:9092/ - tls: //xxxx2:9092/ - tls: //xxxx3:9092/ topic: jb-openshift name: out-audit-logs secret: name: jn-audit-kafka type: kafka pipelines: - inputRefs: - application name: kafka outputRefs: - out-audit-logs 4) Access a Vector pod and check the Kafka config section in vector.toml file (ca_file is not defined) # Kafka config [sinks.out_audit_logs] type = "kafka" inputs = [ "kafka" ] bootstrap_servers = ",xxxx1:9092,xxxx2:9092,xxxx3:9092" topic = "jb-openshift" [sinks.prometheus_output.tls] enabled = true key_file = "/etc/collector/metrics/tls.key" crt_file = "/etc/collector/metrics/tls.crt" Nevertheless, if we do the same process for a single Kafka broker, we can see the configuration in vector.toml file: spec: outputs: - name: out-audit-logs secret: name: jn-audit-kafka type: kafka url: tls: //xxxx:9093/app-topic pipelines: - inputRefs: - application name: kafka outputRefs: - out-audit-logs [sinks.out_audit_logs.tls] enabled = true key_file = "/ var /run/ocp-collector/secrets/jn-audit-kafka/tls.key" crt_file = "/ var /run/ocp-collector/secrets/jn-audit-kafka/tls.crt" ca_file = "/ var /run/ocp-collector/secrets/jn-audit-kafka/ca-bundle.crt"
