1 | Helm Chart Common Templates |
| Schema validation tool |
| 2019-08-22 | Would a schema validation tool/capability make sense? After changes are introduced to schema-service the tool would check schema "integrity" (where integrity is a loosely defined term in this case). There could be rules like -

https://gerrit.onap.org/r/c/oom/+/91553 https://gerrit.onap.org/r/c/aai/oom/+/91550 Use of common templates in the helm charts and have it driven from the values.yaml since all the helm charts are identical except the following things such as volumes, volume mounts, ConfigMap and secrets. The goal is to extract all that information in the values.yaml file and use common templates to enable more consistency. In each of the individual helm charts, we have a filebeat sidecar container, when creating a new helm chart, they just have to say if their chart should enable it or not in the values.yaml. | |||||||||||||||||||||||||||||
4 | 2 | Kubernetes job problem |
| 2019-08-14 | Message to discuss list: https://lists.onap.org/g/onap-discuss/topic/32859796 We have a Dublin environment that had a Cassandra problem which caused the graphadmin-create-db-schema job to fail repeatedly. Question 1. Is there an ONAP-built-in monitoring solution for the shared Cassandra database? The Cassandra problem was a combination of: However, Kubernetes showed node-0 and node-2 still "Running" and apparently healthy (zero restarts), with node-1 in CrashLoopBackOff (many restarts). The Cassandra problems have been manually fixed now, but should ONAP have a monitoring solution built-in to detect it?
Deleting the failed job pods cleaned up the list but did not prompt any new job pods to be created. I think the job has now hit its backoff limit, so it no longer runs, even though we have since fixed the Cassandra problem. The rest of AAI pods are obviously waiting for that job to complete before they can progress out of Init state. Update:
Harish will work on

The unzipped files were owned by root due to previous use of sudo. Removed that directory and unzipped again as normal user. janusgraph.sh start was successful.
Recommend to re-do all the remaining steps again to ensure more success.

Referring to https://wiki.onap.org/display/DW/cloud-region-fromVnf
Wiki page says that output is:
Code Block |
---|
vserver vnfc tenant cloud-region |
but stored-queries.json definition includes:
Code Block |
---|
.createEdgeTraversal(EdgeType.COUSIN, 'vserver', 'pserver').store('x') |
So the output should also include "pserver"?
Also, the wiki page shows
The formatting of the traversal suggests that only cloud-region would be returned, which is inconsistent with the sections above on the same page.
Which one is correct for this case?
This is my attempt at a translation of the Gremlin query into DSL query:
Code Block |
---|
{ "dsl":"generic-vnf*('vnf-id',‘id number') > [ vnfc* > vserver* > [ pserver*, tenant* > cloud-region* ] , vserver* > [ pserver*, tenant* > cloud-region* ] ]" } |
Please confirm whether this is accurate and correct.

Ubuntu node works but Centos node fails.
Problem with releasing artifacts, since self-release is blocked, but LF cannot help with release.
aai-common 1.5.2 appears in nexus, but it looks different from 1.5.1, missing the ".asc" files which appear to be GPG signatures.

From https://lists.onap.org/g/onap-discuss/topic/31317665
Discussion:
- The cloud-region schema element is unusual in that it has a two-part key i.e. "cloud-owner" and "cloud-region-id". There are not many other usages of it ("ctag-pool" , "service-capability" and "route-target" are three others, out of over 100 other schema elements)
- Is it possible to enhance the error message to indicate that part of the key value is missing from the relationship-data?
Jira server ONAP JIRA columns key,summary,type,created,updated,due,assignee,reporter,priority,status,resolution serverId 425b2b0a-557c-3c0c-b515-579789cceedb key AAI-2391 - Is it time to deprecate the relationship-data and switch over to using the related-link only?
- Is there any modeling guidance that would steer new designs away from using multi-part key for schema elements?
- Are there other caveats to using the multi-part key design for schema elements?
- Can we get feedback from Chandra Cinthalaon the key design for multi-part keys and whether this will be more common going forward?

I think we have no plans to deprecate the relation-data option the in the A&AI relationship payload.
It's another option for the client to specify the relationship.
Thanks

Is there a guide for the description of the error message and the error codes? How are new error states (message + code) added?
- William LaMont will send James Forsyth the output of a script that formats the error.properties file to make a wiki page and readthedocs
- James Forsyth should commit that script and create a wiki for the error properties

In think it would be good to answer what is the meaning of the field (collection of PEMs of the CA xor URL)
Questions:
1. Is AAI intended to strictly prescribe how the fields are used and what contents are in the values?
2. Or does AAI simply reflect the wishes of all the client projects that use it to store and retrieve data?
Even if (1) is true, AAI is not really in any position to enforce how clients use the data, so really (2) is always true and we need to consult the original producers of the data and the ultimate consumers of the data to document their intended meanings.
How do we push to have documentation on the purpose and meaning of the fields in AAI?
Where does all this documentation go?
Should the documentation be backed up by validation code?

31st Jan 2019:
The schema-service is ready. Currently it provides file-sharing capabilities in terms of schema/edgerule files.
In order for GraphGraph to take advantage of the schema parsing/processing in schema-service additional abstractions have to be implemented on top of the crude file2string functionality currently in schema-service.
- Venkata Harish Kajurwill ask Manisha Aggarwalif the current functionality of the schema-service is the final version for Dublin and if there will be further enhancements in next releases.
GraphGraph needs the following functionality:
Venkata Harish Kajur and Manisha Aggarwal What is missing in schema service that is needed in graphgraph is the following:
- rest call to get available schemas
- list of all schema nodes/items (like vserver, tenant, p-interfaces..) for example on a REST path /schemas/{schema}/nodes
- all relevant attributes of a given node/item for example on REST path /schemas/{schema}/nodes/{node}
- edges/relationships with their attributes between schema nodes/items (for example on REST path /schemas/{schema}/edges where you specify a "from" "to" schema items as query params)
- subgraph of the schema, where you specify 1. initial (root) items/node (like tenant or vserver) 2. schema version and 3. number of parent/cousin/child hops from the initial item/node
- all paths in a given schema graph between 2 items/nodes (like vserver and tenant) for a given schema version
- edges in the schema graph should be composed of edges in the schema file + edges created from the edgerules file
- edges should contain basic attributes when delivered via the subgraph call (like parent/child relationship and important properties from edgerules) and have additional (or all) attributes when queries via /schemas/{schema}/edges REST endpoint.
20. Mar 2019:
Open questions for schema-service:
- what is the current implemented functionality?
- what are the business use-cases in ONAP for schema-service? Description of functionality in relation to other services/projects is needed. In other words who needs it and why?
- if no business use-cases can be formulated we should consider removing schema-service from A&AI and replacing it with standard file-sharing mechanisms.
21st Mar 2019:
Based on William Reehil comments
https://wiki.onap.org/display/DW/AAI+Schema+Service?focusedCommentId=45299262#comment-45299262 what is "our future proposed functionality"?

AAF will generate certificates to the be used by the containers at startup; AAI services should use the run-time generated certs instead of the ones that are in the repos or oom charts.
In dublin the services will mount a volume with certificates. This is on the roadmap for Dublin as a feature.
- is this for all service and/or HAProxy?
- Where are the certificates coming from (OOM/gerrit/generated by AAF)
12th June 2019: Jonathan Gathman demonstrated aaf-hello functionality at DDF event

Technical solution to either decommission the proxy or make design changes to AAF to enable client side certificates.
After VF2F we will know if this is a requirement in Dublin. We discuss after this date.
question raised: MSB - would client authentication be supported?
- James Forsythcreates a task for encryption of communication between A&AI services and Cassandra
- Tian Lee and Steven Blimkie to report on the Amdocs managed A&AI microservice wheter they support criteria from the Dublin S3P requirements

Brian Freeman asked on Re: Backup and Restore Solution: ONAP-OOM :
what would be the approach to backup an entire ONAP instance particualarly SDC, AAI, SDNC data ? would it be a script with all the references to the helm deploy releases or something that does a helm list and then for each entry does the ark backup ?
What is the AAI strategy for backup and restore?
What is the overall ONAP strategy for backup and restore?
Should it be unified with the data migration strategy as per "Hbase to Cassandra migration" on 2018-11-14 AAI Meeting Notes?
- James Forsythwill raise the topic of having backups and restore functionality in ONAP - if it is feasible, on the roadmap and what others PTL think
Jimmy didn't directly raise the topic but there was movement - Keong Lim asked "if istio service mesh is a no-go, is there a replacement for secure onap communications? is backup/restore/upgradability included in s3p?"
Michael O'Brien replied that a reference tool set for backup and restore was introduced in Casablanca: Backup and Restore Solution: ONAP-OOM
Mike Elliott said he would look at Brian's question, AAI will provide support as needed.
