Error waiting for log message with Docker 20.10.1

Our E2E test suite uses Testcontainers to run our microservices and their dependencies in containers for the duration of our tests. All of the tests were passing until we updated our build nodes to Docker 20.10.1, at which point we started repeatedly getting STDOUT: $Error grabbing logs: unexpected EOF errors, and our Wait.forLogMessage calls started timing out.

Note however, that this issue seems sporadic as about 1 out of 10 builds still passes. After we reverted to Docker 19.03.14 the issue went away. We're using the latest version of Testcontainers (1.15.1 at the time of reporting the issue).

It's unclear to me if this is a Docker/Moby problem or a Testcontainers problem - I figured I'd report it here first to see if anyone else experienced similar issues, as I couldn't find related bug reports on Docker's issue tracker.

Comienza con la suite de pruebas E2E y las llamadas a Wait.forLogMessage; después, reproduce el fallo intermitente de EOF inesperado en STDOUT con Docker 20.10.1 y Docker 19.03.14. En el issue no se especifica ningún archivo ni prueba concretos; se considera terminado cuando se haya identificado si el fallo pertenece a Testcontainers o a Docker y se haya documentado un resultado de regresión verificado.
