(Can I still use this thread?)

Excuse me, I'm trying to run Zuul v3 in my environment, and I have three
question about it.
I'd appreciate it if anyone helps.

My environment)
I use feature/zuulv3 branch, and version is 2.5.3.dev1374.

"Unknown option --die-with-parent" error was occurred when zuul ran job.
Is there requirement of bubblewrap version?

I used bubblewrap 0.1.7-1~16.04~ansible.
If I removed "--die-with-parent" from zuul/driver/bubblewrap/__init__.py,
above error wouldn't occurred.

When I specified "zuul_return" in playbook, the below error was occurred
on remote host.


Should I write a playbook to set a environment variable "ZUUL_JOBDIR"?

Setup module of ansible took long time when zuul ran jobs.
My job was succeeded if I extended timeout from 60 to 120 by modifying
runAnsibleSetup() in zuul/executor/server.py.

But, if I run same job directly(by own), it was finished soon.
Do you have any knowledge about it?

Is there a constructed VM image or ansible for running zuul v3...?

Best regards,

If it's an issue with your job and you can spot it (bad config) just submit a patch with topic 'zuulv3'. If it's bigger/weirder/you don't know - we'd like to ask that you send a follow up email to this thread so that we can ensure we've got them all and so that others can see it too.
