"endpoint with name XX already exists in network bridge" while running withReuse

[lmsurpre]

I can't tell if this is something specific to testcontainers-keycloak or a more generic testcontainers issue, but figured I'd start here.

Previously, I was able to call withReuse(true) on my KeycloakContainer (before starting it) and it would let me re-use the same container from one run to the next which was very useful to reduce the cycle time on test development.

Now, when I try the same thing, everything after the first run is failing with an error like this:

13:07:40.153 [main] ERROR 🐳 [quay.io/keycloak/keycloak:13.0.1] - Could not start container
com.github.dockerjava.api.exception.DockerException: Status 403: {"message":"endpoint with name quizzical_leakey already exists in network bridge"}

I backed out to testcontainers-keycloak version 1.6.1 (where I think this was working before), but it turns out I'm seeing the same behavior there. I'm wondering if its related to some underlying Docker for Mac changes or something...

Please let me know if you have any ideas for me to try.

PS. It works just fine if I manually delete the container after each run, but I was hoping it would let me continue to use the same container over and over (until I decide not to)

I moved this issue into discussions, because a) there was no action in the last few months on it and b) I don't think this is related to this Keycloak Testcontainers implementation, but - IF it's related to testcontainers - it's related to the core testcontainers project.

I somebody thinks he/she has a solution, answers are appreciated and welcome!
