The powershell plugin when used within docker container enters a hang state. I would expect it to fail if powershell core is not installed, which works if the same thing is ran outside docker. The jenkins agent is a Ubuntu 16.04 machine.

I dont see any other process also running within the docker container in the hung state except cat
