ec ps throws TypeError

[ulrikpedersen]

I'm following the tutorial here. When I run ec ps it always throws a TypeError, whether or not I have any IOCs deployed.

I have epics-containers-cli version 3.1.0 installed in my python3.10 virtualenv.

I can see the IOC container is deployed:

Thanks Ulrik. There may be a regression on using docker as we don't try it out all that often.

@marcelldls are you able to check docker usage as part of your tutorials review please? If not give it back to me.

[marcelldls]

Thanks for this @ulrikpedersen - appears to be a subtle difference between the docker and podman APIs for how labels are returned. I can reproduce your issue so I will get it sorted. In future our system tests will catch these

[marcelldls]

@ulrikpedersen Fix is released. Please try pip install edge-containers-cli==3.1.1

[ulrikpedersen]

Very cool, thank you @marcelldls

Works for me with version 3.1.1
