A few days ago we started having a bunch of ci.wildfly.org failures in tests that use Testcontainers. It seems something in testcontainers is incompatible with the current release of Docker[1], so when Docker gets updated things break. Docker was routinely updated on ci.wildfly.org a few days ago and boom... Ken Wills implemented a global workaround for this yesterday. We want to remove that workaround tomorrow unless someone asks in this thread for more time to adapt anything they are running. The permanent fix is to update to Testcontainers 2.0.2, which they released yesterday. We did that for the main branch in wildfly/wildfly and we *think* that's the only thing currently using testcontainers on ci.wildfly.org. But if we're wrong and you need more time before the workaround is removed, please speak up. [1] https://github.com/testcontainers/testcontainers-java/issues/11212 Best regards, Brian
