Subject RE: Important Pending Items
Date Tue, 01 Mar 2016 20:40:38 GMT
Hi Will,

It will be 100% open source. The $dayjob has blocked the team from working on it recently.
I'd like to get some of our ideas into the CloudStack wiki this week before I go on leave
for a week.
Rohit has created a repo for us: https://github.com/shapeblue/Trillian
(which looks a bit sad at the moment - I hope to push our Ansible roles for building mgmt.
servers and Marvin boxes into it this week also)

Internally we're planning a two week sprint on it starting 14th March. Having to dip in and
out of this effort is making it very difficult to get anywhere

I think the biggest part of the work will be to get Marvin up to scratch, the log output from
the tests is pretty bad.

We very much want this to be a community 'thing', and we're happy to work with everyone/anyone
to get there.

Any ideas on the most effective way to have a number of people on this - I'm all ears.
In the meantime I'll try to make good on my promises to get our ideas visible to everyone...

Subject: Re: Important Pending Items

@Paul and @Bharat, thank you for the quality write-ups on this topic.

re:Paul's Details:
I share a lot of your thoughts on this. The hypervisor in hypervisor setup with the ability
to test multiple environments is also core to my thinking. I can't find any details on Trillian,
other than what is in this thread. Is it open source and freely available? This is being developed
at ShapeBlue?

re:Bharat's Details:
This seems like it is the most likely candidate for being able to offer value in the short
term. Thank you for the work documenting it and making the source available. I still need
to review the code. This approach will take quite a bit of work get setup initially, but once
setup, it looks like it will do the trick. By using only freely available software makes it
more accessible than some options which have been suggested in the past.

My thoughts on the topic:
- I think it is important that the CI can test all the different hypervisors and any hardware
integrations available in the environment.
- Ideally the CI tool would be easily distributed and installed at multiple sites. Every company
who depends on ACS will have their own configuration, hardware and mission critical features.
If the CI can be distributed (as independent installs), it will reduce the load on any specific
site and it will enable companies who have specific hardware in their direct path to success
the ability to validate their use case.
- I think a standardized CI output is also important. Ideally the summary of the CI run would
be posted back to the PR thread. I think it is also important to push the detailed logs to
a central location so others can review them. Ideally, links to the detailed logs would also
be pushed to the PR thread.
- I think there should be multiple tiers of testing. Basic simulator testing and full runs.
We may be able to setup simulator testing using a Docker container. I think @pdion891 has
put some work into this that I may be able to build on.
- I think it is probably too ambitious to do CI on every PR before merge, but ideally we would
We may have to only CI the master branch for now and revert any PR that causes it to fail.

I have been digging into this quite a bit today. I will continue working on this as it is
very important to me for the 4.9 release. I would like to setup a CI environment locally as
well to help validate and contribute to the effort. I have some hardware I can throw at this,
so I will be working to get something setup to start testing ASAP.

If I can work off either (or both) of your work, I would appreciate it.

Cheers,
