Micronaut + Vertx + testcontainers - vert.x

Question

How do I configure Micronaut app using Vert.x and testcontainers? I'm trying:
application-test.yml
datasources:
default:
url: jdbc:tc:mysql:8:///db
driverClassName: org.testcontainers.jdbc.ContainerDatabaseDriver
vertx:
mysql:
client:
uri: jdbc:tc:mysql:8:///db
Tests with micronaut-data-jdbc work, but with micronaut-vertx-mysql-client not work:
Error:
Message: Cannot parse invalid connection URI: jdbc:tc:mysql:8:///db
I'm not very familiar with testecontainers, but it seems like it doesn't come up with a fixed port, so I don't know how to configure the connection URI.
Thanks!

Answer 1

It might be a problem that micronaut-vertx-mysql-client does not support the Testcontainers JDBC URL scheme (hard to say without further logs).
In this case, I would suggest to use Testcontainers with database container objects instead of the special JDBC URL.

I got a solution to the problem:
Micronaut + jdbc hikari + vertx mysql client + flyway mysql
