SO CNFM shall process ASD-based CNF Lifecycle orchestration

Pre Condition:

  • ASD and App onboarding package is stored in the Catalog Repository
  • Helm Chart(s) are stored in the Helm Artifact Repository
  • AAI shall support CRUDQ of ASD-based CNF Resources

    • Leverage existing AAI APIs
    • Investigate any new AAI APIs for ASD-based CNF Resources (TBD)

Post Condition:

3.2

Task: Support for SO CNFM NBI API Handler

  • SO CNFM shall support its NBI REST Apis to handle requests from SO.

3.3

Task:

  • SO CNFM shall support the capability to process input parameters from SO, and use the deployment parameters from ASD for the CNF deployment. Those deployment parameter values shall correspond to the parameters defined in the "lifecycleParameters" section(s) of the ASD.

3.4

Task:

  • SO CNFM shall communicate with the ASD Repository to get ASD (descriptor) and artifacts from the ASD repository Manager.

3.5

Task:

  • SO CNFM shall decompose ASD and get the associated DeploymentItems list
    • Get HelmChart references from the DeploymentItems
    • Get ASD from the Repository
      • GET /api/asds/<name> (TBD)

3.6

Task:

  • By leveraging the obtained HelmChart references, SO CNFM shall get associated Helm Charts from the Helm Repository Manager.
    • GET /api/charts/<name>/<version> 

3.7

Option A: use Helm Command:



Option B: use of CNF Adapter (this is not part of initial PoC)

Note: use of CDS is TBD.



Tenant Support

The Tenant support will be realized by Kubernetes cluster, namespace, node and container. Initially, namespace can be used to restrict API access, to constrain resource usage and to restrict what containers are allowed to do.

Assumption & Requirements (from cloud.google.com)

source: https://cloud.google.com/kubernetes-engine/docs/best-practices/enterprise-multitenancy 

The best practices in this guide are based on a multi-tenant use case for an enterprise environment, which has the following assumptions and requirements:

  • The organization is a single company that has many tenants (two or more application/service teams) that use Kubernetes and would like to share computing and administrative resources.
  • Each tenant is a single team developing a single workload.
  • Other than the application/service teams, there are other teams that also utilize and manage clusters, including platform team members, cluster administrators, auditors, etc.
  • The platform team owns the clusters and defines the amount of resources each tenant team can use; each tenant can request more.
  • Each tenant team should be able to deploy their application through the Kubernetes API without having to communicate with the platform team.
  • Each tenant should not be able to affect other tenants in the shared cluster, except via explicit design decisions like API calls, shared data sources, etc.
