In this meetup, we discussed the integration of Gitlab-ci and ArgoCD with the GitOps operator.

1. DevEx | GitOps & ArgoCD
Micro FeedBack Loops

2. DevEx
A Cloud-Native

3. why?

4. Shifting Architecture(s)

5. We tend to take
our work very
seriously

6. Faster!, Higher!,
Stronger!
- More features
- Time To Market
- When Is it ready ?

7. PUT IMAGE HERE
AND CROP AS CIRCLE
Operational Overhead
- The TCO & ROI of the entire
SDLC - is defined by its
operational cost
- More CapEx - Capital (Capability)
exp
- Less OpEx - Operational exp

8. what

9. Developer to “yak shaver”
Some days … more than others

10. Developer to “yak shaver”
Many TOIL’s
along the road
…

11. how

12. Transform
Frustration to
Motivation ?

13. 2019 - RadarCon
Greg Burrell Senior Reliability Engineer, Netflix

15. Much more than just Git !

16. Build your platform - PRODUCT THINKING
What kind of environment would you like want to work in ?
- Interfaces UI / CLI
- Logins
- Context switches …

18. Build your platform - Remote |
Offline

19. Shorter ! Feedback Loops
DOD - Definition of Done
- How do I know it’s done ?
- How does the team know it’s done ?
- How does management know it’s done ?
- How does NOC know it’s functional ?

20. - Revisit -> Re Target your CI / CD processes
- Chosen Frameworks
- Educate your teams / selfs

21. Solution Suggestion
that works
But …

22. Reduce Frustration | Micro Feedback loops ++
● Helper-tools / Utilities
● Make (my personal favorite)
● Kubectx / kubens
● Common functions
○ Set cloud provider project / profile
○ Get a secret from credentials store
● IDE -plugins
● IDE - the obvious
○ Auto lint / build / deploy

23. Developer Self-Service
Cloud Native | like ordering on amazon …

24. Self-Service Cloud Resources
cpu, ram, [ disk, network ]

25. Self-Service Kubernetes Resources
cpu, ram, [ disk, network ]

26. - selfService CI

27. Demo that (should) works
How will our Dev
Experience look
like with GitOps ?

28. If you're seeing this
slide the demo
failed miserably ;)

29. 🚀 Boosting the Developer
Experience
Crawl, Walk, Run, Fly !

30. Shorten them feedbacks !
- Not just standard pipelines
- DAG’s
- Logic which speeds up the feedback loop
- Caches
- …
- Flows based on Git Operations
