Add getR2dbcUrl helper method to JdbcDatabaseContainer

Module

Core

Problem

I might've been chosen the wrong module, sorry for that, haven't found one for all RDBMS containers.

There is a convenient method, getJdbcUrl in JdbcDatabaseContainer. The problem however, if I'm working with R2DBC the connection string schema is different. Currently, I have to create an R2DBC connection string myself, which is a bit tedious.

Solution

It would be great to have a similar method in JdbcDatabaseContainer, like getR2dbcUrl that would construct the R2DBC compliant connection string.

Benefit

This would make integration with R2DBC drivers more seamless and provide better developer experience.

Alternatives

The alternative, I think, is to create the connection string manually, which might be fine, not a big deal, until you have to do it over and over again, in which case it became really frustrating.

Would you like to help contributing this feature?

Yes

Start in JdbcDatabaseContainer and inspect the existing getJdbcUrl implementation, then compare its connection details with the R2DBC URL requirements linked in the issue. The work is done when the class exposes getR2dbcUrl and produces a compliant connection string for supported database containers; verify it against the relevant container tests.
