This guide is geared to provide information regarding how to do service design to automate instantiation and day0 configuration.
Installation
ONAP is meant to be deployed within a Kubernetes environment. Hence, the de-facto way to deploy CDS is through Kubernetes.
ONAP also package Kubernetes manifest as Chart, using Helm.
Prerequisite
https://docs.onap.org/en/latest/guides/onap-developer/settingup/index.html
Setup local Helm
| Code Block |
|---|
helm serve &
helm repo add local http://127.0.0.1:8879 |
Get the chart
Make sure to checkout the release to use, by replacing $release-tag in bellow command
| Code Block |
|---|
git clone https://gerrit.onap.org/r/oom
git checkout tags/$release-tag
cd oom/kubernetes
make cds |
Install CDS
| Code Block |
|---|
helm install --name cds cds |
Design time
Bellow are the requirements to enable automation for a service within ONAP.
Currently, ONAP officially supports instantiation and post-instantiation use cases.
Instantiation use case
The goal is to be able to automatically resolve all the HEAT environment variables, called cloud parameters.
Prerequisite
Workflow
A workflow defines an overall action to be taken for the service; it can be composed of a set of sub-actions to execute. Currently, workflows are backed by Directed Graph engine.
...
Required workflows
The following workflows are contracts established between SO, SDNC and CDS to cover the instantiation and the post-instantiation use cases.
resource-assignment
This action is meant to assign resources needed to instantiate the service. The goal is to resolved all the HEAT environment variables.
...
For each VNF and VF-Module comprising the service, a combinaison of a template and mapping is needed.
The requirement is as ' follow ' for VNF:
${vnf-name}-template
${vnf-name}-mapping...
If any of the mapping uses a source capabbility to resolve a parameters.
config-assign
This action is meant to assign all the resources and mesh the templates needed for the configuration to apply post-instantiation.
...
Combinaison of templates with respective mappings
Scripts if needed
config-deploy
This action is meant to push the configuration templates defined during the config-assign step for the post-instantiation.
