3. Main topic :
The Journey to making an Upstream
Contributing Culture in Korea User Group
3

4. Why do we want to contribute upstream?
We are users and developers of OpenStack.
User group activities are important in the OpenStack community,
but there are many regional-oriented activities.
Contribution is the most direct way to participate in the OpenStack global community.
You can feel the joy of participating in the global community while learning the development
process and culture of openstack.

Group will become closer to the global

Fortunately,
Tringh lives in Korea and he is a searchlight PTL.

10. 10
Let’s try to contribute to searchlight

11. 11
In 2020,
we became mentors for the OpenStack team.

12. 12
Contribute to core components is too difficult

13. 13
Decided to contribute to the SDK and client

14. Contribute to SDK and client
Easy to understand the code structure and flow.
You do not need to know openstack well.
Good for studying openstack and contributing code at the same time.

15. 15
After two years of trial and error, our plan
gradually developed.

16. 2020, Contribution Academy Schedule
Mentoring period : 3 month
1st month : openstackclient code analysis
2nd month : Find the issue from storyboard and solve it.
3rd month : Continue to solve the issue and translate the docs
16

17. Openstackclient code analysis
First of all, you need to know how the openstackclient code works.
It is difficult to know where to start to analyze the code blindly.
So we created a course where we could do our weekly assignments and analyze the code.
You can't contribute upstream, but practice adding new features to your code.

18. Step1 : Add a column in openstack server list
purpose
● Check whether the desired value can be obtained through the api.
● Learn how to control the result screen in cli.
18

19. Step2 : Add a column in openstack server show
Purpose
- Learn how to manage component clients in
the cli and how to get and output data from
multiple components.
19

20. Step3 : Fix a failed test case
After steps 1 and 2, all test cases related to servers fail.
In Step3, we try to modify the failed test case according to the newly added function.
What can mentee learn?
- Learn test case structure of openstackclient, fake/mockup data structure
- How to use Tox

Okay, Now Ready for contribute
Let’s find the issue and solve it !

22. 22
Nope..

23. 23
There are many issues there, but I don't know what to solve

24. 24
Found an issue I want to solve, but I don't know how

25. 25
Openstackclient integrates the cli that each
component has.
Then, there will be instructions that have not
been implemented yet.

26. Mapping Guide
There was a table mapping
Component CLI and
openstackclient.
26

27. Mapping Guide
There are many things that haven't been
implemented yet.
Directed by implementing these
27

28. Developing Unimplemented Commands
Take Glance cli as an example
The implementation method of the not yet implemented command is in python-glanceclient.
Referring to the method implemented in glanceclient, implement similarly to openstackclient.
28

29. 29
In our mentoring, we are continuously working
on adding unimplemented commands to
openstackclient.
