OOM Meeting Notes - 2021-05-12

Agenda

DCAE:
- DMaaP BC onboarding job: @Ajay Deep Singh
  - goal: update / create dmaap topics and feeds
  - two options:
    - stateless mode (post and forget)
    - shared volume (have a shared volume where response are stored)
- ConfigMap Support: @Jack Lucas @Vijay Kumar @Krzysztof Opasiak
  - https://gerrit.onap.org/r/c/oom/+/121238
  - two options are proposed:
    1. simplify developer life and give them simple 'api' in values.yaml in order to add configmap in their deployment
      - pros: simplicity for developpers / "paved playground" / coherent deployment
      - cons: several templates that needs to be created / maintained
    2. don't help too much developpers and allow them to add "code snippets" in values.yaml
      - pros: more "kubernetes way" / help people to understand K8S / less maintenance in OOM
      - cons: maybe steep learning curve / more freedom for developpers means more "unwanted / crazy deployment"
  - questions on "saved lines" "answer": 27 lines are created in order to "save" 3 (another gain is less complexity) so used by 9 configmaps accross all DCAE μs would save it
  - solution proposed: OK for merge (as long as other -1 issues are solved) but "DCAE team" agrees to help to maintain these templates.
ONAP vF2F → first next week
Honolulu Maintenance Release: @Sylvain Desbureaux
- few patches are waiting (to be OK) for being merged on H branch
  - https://gerrit.onap.org/r/c/oom/+/121023 (waiting for gate and verify)
  - https://gerrit.onap.org/r/c/oom/+/121092 (waiting for parent to be OK and merged on master)
Service Monitor: @Marat Salakhutdinov @Lukasz Grech
- https://gerrit.onap.org/r/c/oom/+/119648 (@Marat Salakhutdinov )
  - review in process
    - code is OK for @Sylvain Desbureaux
    - to do:
      Verify prometheus is installed on all gates (@Sylvain Desbureaux )
      Configure ONAP overrided to enable monitoring (@Sylvain Desbureaux )
- metrics on Nodeports (https://gerrit.onap.org/r/c/oom/+/120150)
  - proposal:
    create a new option "internal_only" for port in common.service (@Sylvain Desbureaux )
    
    create a MR on top of it for ves use (@Lukasz Grech )
Bugs in H release → next week
- most of them because AAF is disabled
- maybe work on a specific gate system for that with people who wants it
Kubernetes version and dual stack status update → next week
service mesh initiative rererebooted → next week

proposal for revamping service template:

^{# service configuration}
^service:
^{type: NodePort}
^{name: dcae-ves-collector}
^ports:
^{- name: http}
^{port: 8443}
^{plain_port: 8080}
^{port_protocol: http}
^{nodePort: 17}
^{useNodePortExt: true}
^{- name: metrics}
^{port: 4456}
^{internal_only: true}
^{port_protocol: http}

^{would output:}
