Testcontainers timed out waiting for URL to be accessible | Mockserver Mac M1 compatibility

Exception looks like this:

Caused by: org.testcontainers.containers.ContainerLaunchException: Timed out waiting for URL to be accessible (http://localhost:59262/mockserver/status should return HTTP [200])

Suppose you want to start mockserver docker image on Mac M1. Probably you doing something like this:

DockerImageName containerImage = DockerImageName.parse("mockserver/mockserver:latest");
MockServerContainer container = MockServerContainer(containerImage)
            .withExposedPorts(8080);

Most likely this error happens because of poor docker x86-64 image compatibility with the ARM (M1) CPU architecture.

If you see carefully, then you can find out that some versions of mockserver images (including latest sometimes) may not contain arm-specific image. See https://hub.docker.com/layers/mockserver/mockserver/mockserver-5.13.0/images/sha256-858f26f107c4fa385b9785a719d9fd333bb9cb4d3e6c88fe342822762d334cfd?context=explore, for example.

I suggest you to switch to image version 5.15.0, for example. It has arm-specific build:

DockerImageName containerImage = DockerImageName.parse("mockserver/mockserver:5.15.0");
MockServerContainer container = MockServerContainer(containerImage)
            .withExposedPorts(8080);

See https://hub.docker.com/layers/mockserver/mockserver/5.15.0/images/sha256-b8a8bc5042b6fd7fbe0acfbf81b23a5f576579fae48fcdecb676c9492905341d?context=explore.
