Documentation incomplete or code bug?

@Keong Lim

Saw this change https://gerrit.onap.org/r/#/c/81867

which configures the AAI URL path "aai.serviceInstanceQuery=/aai/v13/nodes/service-instance/{0}"

According to documentation: https://onap.readthedocs.io/en/casablanca/submodules/aai/aai-common.git/docs/AAI%20REST%20API%20Documentation/nodesQuery.html#api-uri

The URL path should have been "/aai/v13/nodes/service-instances/service-instance/{0}" but tests show that both URL paths work equally well.

Is the documentation incomplete? or is there a code bug letting it pass through?

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)

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



5



Strange dependency in ESR

@James Forsyth

Can anyone look at this one?

Blocker

@J. Ram Balasubramanian

AAI-2202: Cannot execute POMBA on latest master due to A&AI IssueClosed

Documentation on the search/nodes-query API is missing. @James Forsyth needs to find it and publish it.
7



Documentation request

@Taranjit Singh (Deactivated)

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. @Former user (Deleted) 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.

OOM helm charts

@James Forsyth @Venkata Harish Kajur

Migration of the oom / aai charts to an new repo that we will have commit access to. Harish tried to preserve the history on the existingn set of files, but there was no way to do it because the commit messages would violate the 50 character limit. So we will lose history on the commits and do the push as a new code drop.

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.
