This page basically acts as my PowerPoint presentation, but without PowerPoint and as GardWiki page.

It should be treated like an outline, which should give you all the good links and a basic outline, of how we use Argo CD at DT for ONAP.

The official Argo CD page:
- https://argoproj.github.io/cd
So Argo CD helps us, doing GitOPs, but what is GitOPs, and basically why is it important, was perfectly answered by Cornelia Davis
- KubeCon: GitOps Is Likely More Than You Think It Is - Cornelia Davis, Weaveworks
A more recent recorded version of that talk exists as well:
- GitOps Is Likely More Than You Think It Is (only 21 views, I was one of them). Both talks are 99% similar, but the first one is more on point.
The slides of the two talks can be found here:
- https://static.sched.com/hosted_files/kccncna20/39/GitOpsIsMoreThanYouThink.pdf
- Remark:
  - Show slide 3 - What is GitOps
  - Show slide 17 - Decouple CI from CD
Argo CD - a tool for CD, but what says the CNCF Landscape about it.
- https://landscape.cncf.io/
CNCF Landscape - Continuous Integration & Delivery
- https://landscape.cncf.io/card-mode?category=continuous-integration-delivery&grouping=category
There are at least 44 tools regarding CI & CD. (checked 24 Nov 2021 )

Why Argo and not Flux
- Flux CD joins forces with Argo CD project
And consider: CNCF - The Trail Map

Argo CD at TNAP

Recently Andreas and Marc gave a talk:
- LFN Webinar: Deutsche Telekom Deploys ONAP In O-RAN Town (Timestamp 25:51)

Two scenarios:

Deploy gitlab runner into one k8s cluster

Just for learning and getting a feeling
The runner settings in Gitlab

install the runner in a different cluster like tesla-dev

start with version 0.33.1 update it later to 0.34.0

add it to all kustomization.yaml's

now update it to version 0.34.0

Update an existing ONAP component
- oom from onap

  - https://gerrit.onap.org/r/gitweb?p=oom.git;a=tree;h=refs/heads/istanbul;hb=refs/heads/istanbul
- In our case, we split the oom repo into several repos. One helm chart repo for each onap component.
- and yesterday we had the increase the internal version number of dmaap (from 8.0.1 to 8.0.1-1)

- and we put it into our artifactory (JFrog), similar to nexus
- Now we need to update it in our argo-management repo to the version 8.0.1-1 as well
- and watch it in Argo CD, how it is being updated

Outlook were we like to get better:
