Comment 20 for bug 1734983

1 minor regression found in the docker plugin execution.

-------------------------------------------------------------------------------------------------
When running soreport with docker installed we get an exception in the plugin as follow :

...
 Setting up archive ...
 Setting up plugins ...
caught exception in plugin method "docker.setup()"
writing traceback to sos_logs/docker-plugin-errors.txt
...

# cat sos_logs/docker-plugin-errors.txt
Traceback (most recent call last):
  File "/usr/share/sosreport/sos/sosreport.py", line 1252, in setup
    plug.setup()
  File "/usr/share/sosreport/sos/plugins/docker.py", line 126, in setup
    super(UbuntuDocker, self).setup()
  File "/usr/share/sosreport/sos/plugins/docker.py", line 100, in setup
    for container in containers:
NameError: name 'containers' is not defined

-------------------------------------------------------------------------------------------------

This upstream fixes the above situation:
https://github.com/sosreport/sos/commit/68e149809d5b487d0c5800b5a1a005aaad83c7be

I have forwarded the bug and my analysis to Debian :
