[jira] [Commented] (BEAM-7857) Portable Wordcount on Flink runner finishes but does not produce output files in DOCKER execution mode

["Ștefan Istrate (Jira)" <ji...@apache.org>]

Ștefan Istrate commented on BEAM-7857:
--------------------------------------

I'm also trying to figure this out. Can't Docker mount a host folder to the container, so that the local and outside-of-docker filesystems interact properly? How can I achieve this with Beam?
