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 (Nokia)

  • 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 (Nokia) )

• 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:
