Tracking of designs of functionality and API

1, F-GPS:

Please refer to the patch https://gerrit.onap.org/r/#/c/78634/ which elaborate how to enhance current API to support F-GPS.

The AZ names should be discovered by multicloud discovery/registry process, the AAI schema can be reused without change:

3, FCAPS enhancement

4, Multi-Tenant Support

So far MultiCloud exposed API with ID of a cloud region, assuming the consumer will issue the API request with the default tenant which are part of the AAI cloud region. With that the different tenants on the same VIM/Cloud instance can only be on-boarded into ONAP as different cloud regions.

To support the vision of enabling multiple tenants on the same cloud region, multicloud could help from following aspects:

a, discover all tenants from the VIM/Cloud instance and register them under one AAI cloud region, this is already done if the tenant user comes along with privilege to get list of tenants of the VIM/Cloud instance.

b, MultiCloud NBI should allow consumers to specify the tenant name/id during the requesting the API to MultiCloud. This can be done on various way, the easy and backward compatible approach is to having consumers putting the tenant ID/name into the "optional" request headers of the Rest API call.

5, Secured-communication enablement

The multicloud services which are based on uwsgi could utilize the https feature of uwsgi: https://uwsgi-docs.readthedocs.io/en/latest/HTTPS.html

The question would be: who/how to generate key and cert ?

Follow the practice of MSB project, multicloud service will generate our own keys/certs and put them in the docker by default. And also make sure these keys/certs can be overrided by OOM helm chart , just like the logging settings.

6， Security Requirement: Run microservice as non-root user

Reference: https://gerrit.onap.org/r/#/c/78803/

Make sure you test it with healthcheck API

7, Docker image footprint optimization

Reference:

Exercise on multicloud broker: https://gerrit.onap.org/r/#/c/79582/

Local try, observed image size drops from 846MB to 296MB:

dockerfile changes

Image footprint
optimization exercises:

1, original
dockerfile => (multicloud-broker-orig: 846MB)


Dockerfile:


FROM
python:2

2, rebase to
python:2-slim => (multicloud-broker-slim1: 410MB)


Dockerfile:


FROM
python:2-slim

apt-get install -y unzip gcc

pip install -r ...

apt-get remove -y unzip gcc



3, remove unused
packages => (multicloud-broker-slim2: 296MB)


Dockerfile:

FROM
python:2-slim

apt-get install -y unzip gcc

pip install -r ...

apt-get remove -y unzip gcc
