[olug] Docker + xinetd??

[Justin Reiners]

Sorry to bother, maybe someone here knows.

Has only had luck running xinetd within docker? I've got some older legacy
stuff written in python, which takes input on stdin I use xinetd to
operate. I've been trying and failing for about 2 days now...

I appreciate any ideas on why the entry point doesn't seem to work, the
docker instance seems to hang.

Searching for "xinetd + docker" seems to be a lost cause.


*Dockerfile:*
