Here is what I ended up doing to make it work.
I copied the MySQL connector jar file to the logstash directory then added an ADD command
ADD mysql-connector-java-8.0.17.jar logstash-core/lib/jars/
to my Dockerfile
in my pipeline/logstash.conf I blanked out the following parameters:
jdbc_driver_class => ""
jdbc_driver_library => ""
This is some sort of work around and is supposedly fixed but has yet to be included in Logstash from what I've been told.
