Hey! I am having this really weird intermittent issue when building a Docker image containing a pex. The weird part is that it does not re-occur if I just run the same target / goal. I am on an M1 Mac, and I am running Pants from the latest commit on main. Update: Now Pants just won't work. It's cycling through four different error messages each time I try to run
pants package
.
pants run
works fine!
Am I missing something obvious here or should I file this as a bug / issue on Github?
Ok, now it's cycling these three four error messages:
Copy code
Engine traceback:
  in `package` goal

Trying to delete the cache now.
Did not work.
I think this is related to the fact that I am using the Docker environment, since run works fine.
After some more noodling, I am getting RequestTimeoutError issues towards Docker:
Copy code
Failed to start Docker container `fcfe131491c6435b21c2f1fe4c446b5260378113cd775e91f49230599cc1bbfc` for image `sha256:e4bf78b64f77acd1f2201a360900c645575cd5aefdf46d4cc5025194651f30ac`: RequestTimeoutError
Ok, got things working again after a reboot and flushing all of the cached files, as well as deleting docker containers that were hanging around. Weird!

Ouch, sorry for the trouble!
Would you mind filing an issue with all this detail, as well as your pants.toml and the contents of relevant BUILD files?
It sounds like you're using the new environments feature? It's new so still has sharp edges

Yeah, I'm running Docker environments for builds. Will file the issue today!
Don't worry about it, I expected some issues since the feature is so new.
Hey sorry, having a hard time reproducing this and a lot of work to do, so my issue hasn't been filed yet. It's on its way!
I am pretty sure it has something to do with deleting the container that pants spins up and leaves running in the background. Not sure what that does.
