What happened?

I'm trying to debug my LocalStack container in a CI environment and for that I would like it to not be deleted after the tests so I can read its logs after.

I followed the steps described in the doc, which means opting-in Reusable Containers (testcontainers.reuse.enable=true in ~/.testcontainers.properties), adding withReuse(true) and starting the container manually:

LocalStackContainer localStackContainer =
    new LocalStackContainer(DockerImageName.parse("localstack/localstack:2.0.2"))
        .withServices(
            Service.DYNAMODB,
            LocalStackContainer.EnabledService.named("events")
        )
        .withClasspathResourceMapping("testcontainers/init-scripts", "/etc/localstack/init/ready.d",
            BindMode.READ_ONLY)
        .withEnv("DEBUG", "1")
        .withEnv("HOSTNAME", "localstack")
        .withEnv("HOSTNAME_EXTERNAL", "localstack")
        .withEnv("SKIP_SSL_CERT_DOWNLOAD", "true")
        .waitingFor(Wait
            .forLogMessage(".*localstack just finished starting.*", 1))
        .withStartupTimeout(Duration.ofMinutes(10))
        .withReuse(true);
localStackContainer.start();

But unfortunately, after the tests ran, docker ps -a doesn't show any localstack container.

Relevant log output

No response

Reusable Containers is an Experimental feature and there is a note in the docs too.

Reusable containers are not suited for CI usage and as an experimental feature not all Testcontainers features are fully working (e.g., resource cleanup or networking).

I believe the team is working on this feature.

I have just tested it locally and it is working as expected. I suppose should work in a CI environment too if you have control of the runners e.g. GitLab Runner. 🤔

I'm not able to reproduce either. Please, make sure Reuse is what you need, take a look at Singleton Container Pattern.

Feel free to reopen the issue adding a reproducible project and more info.
