How to create a MySQL cluster within an Istio injected namespace? - mysql

Question

I'm currently trying to create a 2 nodes MySQL cluster in an 1.13.10 K8s using the Oracle MySQL Operator. It works fine within a standard namespace. However, once it's created within an Istio 1.4 injected namespace, the MySQL Agent, that is in charge of setting the replication up, returns the following error:
Error bootstrapping cluster: failed to create new cluster: SystemError: RuntimeError: Dba.create_cluster: ERROR: Error starting cluster: The port '33061' for localAddress option is already in use. Specify an available port to be used with localAddress option or free port '33061'.
I was not able to find any support on this so far.
How can I configure Istio to enable the agent to manage the replication ?
