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.

Inizia con la suite di test E2E e le chiamate a Wait.forLogMessage, quindi riproduci il fallimento intermittente di EOF imprevisto su STDOUT con Docker 20.10.1 e Docker 19.03.14. Nell’issue non sono indicati file o test specifici; il lavoro è completato quando si è identificato se il fallimento appartiene a Testcontainers o a Docker e si è documentato un risultato di regressione verificato.
