@bcipriano @DiegoTavares There seems to be an issue in the sample job submitted in the integration test script:

OpenCue/samples/pyoutline/basic_job.py

Lines 28 to 33 in b21aa6b

	ol = outline.Outline(
	'basic_job', shot='shot01', show='testing', user=getpass.getuser())
	layer = outline.modules.shell.Shell(
	'echo_frame', command=['echo', '#IFRAME#'], chunk=1, threads=1, range='1-5')
	ol.add_layer(layer)
	outline.cuerun.launch(ol, use_pycuerun=False)

Despite being a simple job, the wait_for_job function reports the job as pending until it times out:

Would appreciate some thoughts on this.

It looks like the job is not being picked up by rqd, which means rqd might not be coming up as expected, or not configured properly on the integration test to be assigned to the right allocation. Can you confirm the rqd version created by your dockerfile is running as expected in isolation (outside of the test environment)?
