Prefer use of (non headless) services. Pod to pod communication is not a first class citizen in a Service mesh (as the name stands). Thus using non headless services in the preferred way.
Listen at least on 127.0.0.1. Service Mesh sidecar will listen on the public POD IP. If the traffic is allowed, it needs to pass it to the "real" POD. For that, it sends it to 127.0.0.1. Then, the POD must listen on this interface
Name the ports in the service / pod with their protocol. In order to detect protocol, service mesh tends to use the naming of the port (on the service and pod part). Naming it "foo" doesn't help whereas "http" or "http-foo" helps the service mesh provider to know which protocol is used. allowed protocols are "tcp", "http", "https", "http2", "grpc".
Allow to disable https (or enable http). As the ssl part can be done by the service mesh, there's no need to do it on the pod side. Thus, we should be able to disable https (or enable http).
If Service 2 Service authorization is needed, per service service account must be created as service mesh implementation uses service account for Authorization

Principles specific to ONAP

As AAF is used for certificates generation and as AAF is not compliant with service mesh, we need to be able to disable AAF integration in ONAP components.

Plan of work

Focus first on the “core” part of ONAP, i.e. the one allowing to onboard and instantiate a service.

On this core, build from the ground, i.e. the services infrastructure and go up to the other services

Order of Service Mesh onboarding:

DMaaP
AAI
SDC
SO
SDN-C
Multicloud

...

DMaaP

Image Removed

Components

3 main components:

Message router
Data router
Bus controller

"Databases"

Message router relies on Kafka (which relies on Zookeeper)
Data router relies on Mariadb galera
Bus controller relies on postgreSQL

Work Done

Patch files for DMaaP (careful, it's hardcoded) and Postgres

View file

name	sm_dmaap.patch
height	250

View file

name	sm_postgres.patch
height	250

Generic work

Jobs

Force service mesh to be disabled on every job by adding these annotations in the POD metadata (not in the Job metadata):

...

JIRA Tickets created for Service Mesh

EPICS

Components on Service Mesh EPIC

Components Service Account creation EPIC

Service 2 Service Authorization EPIC

Customer 2 Service Authorization EPIC

Component Internal support for Customer Authorization EPIC

Service Naming

Istio asks to set the type of protocol in the port name (https://istio.io/docs/ops/configuration/traffic-management/protocol-selection/). As DMaaP is exclusively http/https, I've added http- or https- in front of port names (hardcoded).

HTTP call

As istio is dealing (or not?) with mtls, http is sufficient. So every configuration with https should be move to http

Kafka

Kafka and Zookeeper from Message router seems not to be “service mesh compatible".

I've decided to to switch to banzaicloud kafka operator (which claims being istio compatible and use the same images for kafka)

Installation

I have on the cluster 3 storage classes:

default (Cinder backed by CEPH HDD)
ssd (Cinder backed by CEPH SSD)
ssd-kafka (same as SSD + the following value: volumeBindingMode: WaitForFirstConsumer) as banzaicloud propose to do (https://github.com/banzaicloud/kafka-operator/#installation-1).

Per default, Message Router uses its own kafka and zookeeper clusters (charts cannot be disabled and configuration is set).

Here's what to do:

Change Zookeeper and Kafka Address in Message Router configuration

This obviously hardcoded but we can think of a more generic approach

Mariadb Galera

Mariadb galera was working out of the box with a replica of 2. The only issue is that their internal communication is not seen and appears as 'PassthroughCluster'.

So I tried bitnami-mariadb charts (with replica of 3) but we have the same "issue" .

→ Moved back to "our" chart.

Postgresql

common postgres cluster chart doesn't work at all with service mesh:

the installation use a statefulset but with some "voodoo" in order to specialize the deployment
pgpool is not used (by DMaaP) nor can work (as passwords are hardcoded)

So I decided to recreate the chart with (specialized) deployments instead of a statefulset + make pgpool work with specific users (but only at launch for now) + use secrets with pgpool.

Cassandra

We must force Cassandra to listen on 127.0.0.1 and to use POD IP for broadcast.

Nothing to do

AAI components

all AAI components are using spring boot.

They're using https per default.

Adding the following lines on application.properties allow to move back to http:

security.require-ssl=false
server.ssl.enabled=false

we also need to use the different REST endpoint with http instead of https.

One example via many other: -schema.service.base.url=https://aai-schema-service.{{ include "common.namespace" . }}:8452/aai/schema-service/v1/ +schema.service.base.url=http://aai-schema-service.{{ include "common.namespace" . }}:8452/aai/schema-service/v1/

On the global part, we need to remove aaf, aaf-profile hand change client service schema to no-auth:

---
global:
   aafEnabled: false
   installSidecarSecurity: false
   config:
     profiles:
       active: production,dmaap
     schema:
       service:
         client: no-auth

HAProxy

"Main" entrance of AAI is actually an HAProxy. Instead of doing that, we could use a VirtualService from istio:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: {{ include "common.servicename" . }}
  namespace: {{ include "common.namespace" . }}
  labels:
    app: {{ include "common.name" . }}
    chart: {{ .Chart.Name }}-{{ .Chart.Version | replace "+" "_" }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
spec:
  hosts:
  - {{ include "common.servicename" . }}
  http:
  - name: "search-data"
    match:
    - uri:
