Hi, I gradually migrate a huge repo we have from a Docker-based infra we have to Pants. Lately, we've started to have sporadic cases in which CI fails due to networking issues. We've found that it could happen from over-using Docker. We currently replace in the testing phase a Pytest Docker with

pants test

. Just to make sure: does Pants/Pex's sandboxing has a virtual network interface or anything related that could have a race-condition with Docker when creating a container?

No. The local sandboxing just consists of running in a temporary directory with snapshots of files from the workspace. There is no attempt to handle network at all.

Thanks! Currently, I'm not sure about anything and some of our systems still use and old version of Ubuntu and Docker. Anyway, will look for the reason somewhere else - thanks again 🙂
