NFVO added to ESR

@t

can we discuss in this meeting on NFVO as new node in esr system info for the SOL 005 usecase: Support ETSI NFV-SOL 005 (Os-Ma-Nfvo ref point ) between SO & VF-C/NFVO

AAI-2194: Support ETSI NFV-SOL 005 (Os-Ma-Nfvo ref point ) between SO & VF-C/NFVOClosed

Container Images

@James Forsyth

Container Image Minimization Guidelines

@James Forsyth will compile the set of instructions for building docker images,:
For resources, traversal, graphadmin, cacher, and schema-service, all of the images can be built via this:
mvn -Pdocker clean install -DskipTests -Dcheckstyle.skip=true, dockerfile are locatedsrc/main/docker/Dockerfile
Amdocs microservices have instructions in the wiki, collate this into a single wiki page
Recommended docker version - should tie to kubernetes version (maybe link to ONAP wiki page)

schema-service has v16 files

@Keong Lim

Is v15 API for Dublin release? AAI-1811: Add support for v15 version of APIsClosed

Why does schema-service now have v16 files? AAI-2161: Add support for v16 version of APIsClosed

@James Forsyth Document nodes wiki and add explanation about presence of the v15 file. Should add v14-v15 changes to release notes.

Dublin: circular dependency between aai-common and schema-service causes build failure

@Keong Lim

While building aai-common, aai-common/aai-core has dependency on schema-service (build fails).

While building schema-service, schema-service/aai-schema-gen has dependency on aai-common/aai-schema-ingest (build fails).

Seems like a circular dependency between aai-common and schema-service, with both builds broken on the first pass.

On the second or subsequent passes, there might be enough libraries built to make it work again, but that's very unclean.

Currently, it might be passing when downloading artifacts because it's actually pulling older versions from maven repositories, similar to the "second or subsequent passes" described above.

Pulling from maven repositories is no good for testing changes to schemas in local dev environments (won't see the new schemas in the microservices, see also step 7 of AAI Tutorial-Making and Testing a Schema Change - Dublin messing around with "mvn versions:set -DnewVersion=0.0.1-TEST-SNAPSHOT" etc).

The build should be a DAG (directed acyclic graph) and work on a single-pass.

These really should not be separate repositories. There's too much coupling between the microservices to sensibly keep them as separate repositories. A single repository can already have multiple microservices/libraries/etc as artifacts.

@Venkata Harish Kajur create oxm files for the junits in aai-core to remove the coupling to the schema service to prevent circular dependency

Run AAI containers as non-root user

@James Forsyth

https://wiki.onap.org/display/DW/Best+Practices

  • The Docker and Kubernetes engines may run as root until such time as the products support non-root execution.

  • Applications may run as root within a container.

  • The process ID of a container must not run as the root ID with the exception of containers supporting ONAP features that require the container to run as the root ID.

  • Containers may run with root privileges.

  • Project containers that run as the root ID must document this in the release notes along with the functionality that requires the container to run as the root ID.

Encourage our clients to migrate off named query

Trying for Silver badge and Level 2 on Security; 50% code coverage on repos

Resiliency and fault tolerance; meeting notice never published,

@James Forsyth will set up session using zoom for next week, due 10 Feb - update, Re-requested for 2/19

CSIT on OOM needs to cover more of the services - no volunteers to look at this

Moving Helm charts into AAI repos

@Former user (Deleted) is the AAI contact for doing the helm chart migration, info passed along to Mike Elliot

CSIT Robot Integration Sanity Test Cases



Need to maintain these for Dublin, and expand to include things like MSB integration. Establish a working group to develop CSIT test cases for Dublin and document them on the wiki. @James Forsyth will create the page and solicit ideas.

AAI data model principles document



@James Forsyth will set up a separate session to provide ideas on what should be in the document

Looking to bring in SME who would document rules for A&AI schema principles, define design principles for data model. Document will serve as reference during code reviews for A&AI data model. @Chandra Cinthala is identified as the resource who will co-ordinate the activity

AAI Dublin wiki updates

@Keong Lim



Added pages to AAI in Dublin Release

@Venkata Harish Kajur could you please update procedures for schema-service implementation?

Will need this to work on Dublin schema changes (e.g. BBS use case)
