The library comes with examples for the adapter and a Dockerfile for running the example scripts.
Run make up.
You will start at a bash prompt in the /opt/php-pubsub directory.
If you need another shell to publish a message to a blocking consumer, you can run make shell
To run the examples:
$ php examples/KafkaConsumerExample.php $ php examples/KafkaPublishExample.php (in a separate shell)
