Getting error while running targeted

[sham-more24]

Hello,

I'm encountering an issue when trying to run a targetd/docker/Dockerfile. Building the container successfully creates the image, but I encounter an error when attempting to run it. Below are the logs of the error for reference.

Could you please assist me in resolving this issue?

Looks like a few different issues.

1. The container doesn't have python-gobject libraries. In fedora this would be packages python3-gobject-base, python3-gobject-base-noarch, python3-gobject.
2. The command line syntax for zfs has changed, breaking the code that is wrapping it, not uncommon, but unfortunate
3. pkg_resources is deprecated

I'll be able to take a look at this more next week

@tasleson Sure I will wait for your further reply and also I wanted to ask you one more question that is can targetcli be run inside docker container of open-iscsi ?

I can't think of any reason at the moment why this wouldn't work, assuming you've given the container all the needed privileges and visibility to needed FS paths etc.
