getBoundPorts failing in Github Action environment

[wilzwert]

I stumbled upon a problem while trying to use a RabbitMQ testcontainer with phpunit in my CI (github action) for a basic Symfony 7.3 project.

I use a GenericContainer :

$container = new GenericContainer(self::RABBITMQ_VERSION)
            ->withExposedPorts(self::RABBITMQ_PORT)  // AMQP port 
            ->withEnvironment(['RABBITMQ_DEFAULT_USER' => 'test', 'RABBITMQ_DEFAULT_PASS' => 'test'])
            ->withWait(new WaitForLog('Server startup complete', false, 30000))
;

The container starts, the WaitForLog strategy does its job, but then the getFirstMappedPort method fails to return a port.
Other testcontainers (PostgreContainer and RedisContainer) work as intended.

I suspect it may have to do with the container being not fully started when the inspect method of the StartedGenericContainer is called, resulting in a cached inspectResponse without container ports data.

As a workaround I created a custom wait strategy which forces new inspection in a loop until ports are actually available, and it actually worked.

Could this be related to the 'Container Startup Reliability' mentioned in this PR #42 ? My issue and solution seem consistent with the temporary fix in this PR (300ms delay added in the getBoundPorts method).

Edit: actually I had to decorate the WaitForLog strategy with my own, so that my custom strategy first awaits for bound ports, then calls the original WaitForLog.
