Configures producer options for the Kafka Bridge as keys.

The values can be one of the following JSON types:

* String
* Number
* Boolean

You can specify and configure the options listed in the {ApacheKafkaproducerConfig} with the exception of those options which are managed directly by Strimzi.
Specifically, all configuration options with keys equal to or starting with one of the following strings are forbidden:

* `ssl.`
* `sasl.`
* `security.`
* `bootstrap.servers`

When one of the forbidden options is present in the `config` property, it is ignored and a warning message will be printed to the Cluster Operator log file.
All other options will be passed to Kafka

IMPORTANT: The Cluster Operator does not validate keys or values in the `config` object.
If an invalid configuration is provided, the Kafka Bridge cluster might not start or might become unstable.
Fix the configuration so that the Cluster Operator can roll out the new configuration to all Kafka Bridge nodes.

There are exceptions to the forbidden options.
For client connection using a specific _cipher suite_ for a TLS version, you can xref:con-common-configuration-ssl-reference[configure allowed `ssl` properties].
