If you have a file named .testcontainers.properties in your ~ and add: testcontainers.reuse.enable=true

Can we have this documented somewhere before merging this PR?

Where would you look for it? It's a bit specific to Testcontainers

Perhaps in https://github.com/quarkusio/quarkus/blob/main/docs/src/main/asciidoc/dev-services.adoc as a separate section?

thanks for the hint @gastaldi , added a couple paragraphs.

At this time it's limited to containers used for relational databases so I've only mentioned it in that section; we can expand on this later if people find it useful.

Would we want to wrap the config for this into the devservices config, rather than need an additional file to config with?

+1 from me. I had looked at re-use before but I thought it was just for re-using containers inside the same JVM, I did not realize the container could survive JVM exit.

I have wondered the same, but Testcontainers doesn't expose this. We would need to either hot-patch it or to overwrite the user's configuration file - not nice.

And it's a rather advanced option of Testcontainers, I think for now I'd rather have the users aware that it's Testcontainers stuff and that they refer their documentation + configuration; it might have other implications and there's more tuning options that I haven't mentioned here.
