Docker and Pants question: Do you use a different

.pantsd

directory when running

./pants

in a Docker container? What about any

*.pyc

files created if you share your repo inside your container? Do you share your repo inside your container?

I just mount my cache dirs, but I'm running into intermittent problems doing that, so I'd like to see a better answer if possible

i would suggest against trying to share

.pants.d

… but anything in the home directory should be safe to share.

v2 doesn't seem to have a local

.cache

either

correct

and this is safe/efficient to share across runs?

the v2 native “build cache” (the cache of Processes that pants has directly executed in sandboxes) is located under

~/.cache/pants/lmdb_store

See https://www.pantsbuild.org/docs/troubleshooting#how-to-change-your-cache-directory about the different folders used

Are there lock files or issues with running two processes of pants against the same repo?

@jolly-midnight-72759: it is completely safe, but concurrent runs of pantsd in the same workspace are not supported currently (the `N+1`th runs will report that they are waiting), so if you want multiple runs, one of them would need to pass

--concurrent

(which effectively disables

pantsd

).
