  Will need to add the file for the haproxy in values.yaml since a limit on secrets meant we had to bake it into the haproxy container previously

GraphGraph is coming

RestClient updates are potentially being contributed by community members

Champ slipped below 55% with latest commit.

• Tian Lee will do babel, model-loader, champ, gizmo, event-client, spike, rest-client, validation
  
• Arul Nambi will do sparky-be, search-data-service, data-router, logging-service, router-core
  
• Venkata Harish Kajur will check aai-common, resources, traversal, graphadmin, cacher, schema-service (which probably already have the setting)
  
• Add thresholds to all repos that are above 55% so it doesn't happen again
• For setting the threshold on each repo, set it to the current percentage, so if it's is at 62.7%, set the threshold to 0.62

•  <jacoco.line.coverage.limit>0.68</jacoco.line.coverage.limit>

Added pages to AAI in Dublin Release

• AAI Developer Environment Setup - Dublin
• AAI Tutorial-Making and Testing a Schema Change - Dublin

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)

12th Mar: messages from onap-discuss list and wiki comments show that there is still confusion and/or missing steps for the Dublin tutorial, need to sync with current code

18th Mar: David Perez Caparros had problems with v16 in AAI-2154 - Getting issue details... STATUS .

Noticed several gerrit reviews for API v16 support:

• https://gerrit.onap.org/r/#/c/82056/
• https://gerrit.onap.org/r/#/c/82541/
• https://gerrit.onap.org/r/#/c/82542/
• https://gerrit.onap.org/r/#/c/82543/ 

Either it was premature to make v16 known during Dublin development or they should be co-ordinated for earlier in the cycle.

Note that these changes also include deprecation of v8 and v9. Is that new change or catching up on old changes?

Again, reinforces a sentiment from previous meeting "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."

Related to "rolling upgrades", I would rather see a system where old versions can be disabled by stopping pods/containers and new versions can be enabled by starting pods/containers, with the haproxy or MSB directing requests to appropriate api-version-based servers for processing.

Is that a future that should be discussed with Stephen Terrill in ONAPARC e.g. ARC AAI Component Description - Dublin ?

James Forsyth

Can anyone look at this one?

AAI-2202 - Getting issue details... STATUS

• Documentation on the search/nodes-query API is missing. James Forsyth needs to find it and publish it.

Taranjit Singh

Understanding the architecture of AAI is not easy - hard to understand how the code is laid out and how things flow. Need documention which will describe how the microservices are connected, which repos support which functions, etc. Pavel Paroulek says that he had to reverse engineer the dependencies to see how the repos are connected. Recommended to focus on the resources repo for understanding the core function of AAI.

Is v15 API for Dublin release? AAI-1811 - Getting issue details... STATUS

Why does schema-service now have v16 files? AAI-2161 - Getting issue details... STATUS

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

• 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.

AAI-2172 - Getting issue details... STATUS

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
