• 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

    • 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)
