Kustomize configs for installing CNF features and e2e functional tests for verifying feature deployment/integration

Overview

This repo contains example kustomize configs used to installed openshift features required for CNF workloads and a e2e functional test suite used to verify cnf related features.

Contributing kustomize configs

All kustomize configs should be entirely declarative in nature. This means no bash plugin modules performing imparative tasks. Features should be installed simply by posting manifests to the cluster. After posting manifests, determining when the cluster has converged on those manifests successully should be observable.

Usage

Prerequisites

• You need a running OCP 4.4 cluster and a valid KUBECONFIG.
• You need at least one node with the node-role.kubernetes.io/worker-cnf="" label and a MachineConfigPool matching worker-cnf machine configurations
• You need to install jq (a command line tool for parsing JSON) on the local machine.

You can run make setup-test-cluster to have the first two (or the first in case of only one) workers labeled as worker-cnf and to have the MachineConfigPool created.

Configuring

All the Makefile rules depend on two environment variable, either for deploying, waiting and choosing what tests to run.

FEATURES

i.e. FEATURES="sctp ptp sriov", drives what features are going to be deployed using kustomize, and what tests are going to be run.

The current default values is "sctp performace"

FEATURES_ENVIRONMENT

i.e. FEATURES_ENVIRONMENT=demo determines the kustomization layer that will be used to deploy the choosen features.

The current default values is e2e-gcp

Deployment

For each feature choosen via FEATURES we expect to have a layer either in feature-configs/deploy or in feature-configs/$FEATURES_ENVIRONMENT.

• run FEATURES_ENVIRONMENT=demo make feature-deploy.
  This will try to apply all manifests in a loop until all deployments succeeded, or until it runs into a timeout.
• optionally run FEATURES_ENVIRONMENT=demo make feature-wait to be notified of when the features are deployed.

Testing

We expect to have a section of the test suite named after each feature we want to test (for example sctp named after the sctp feature).

External tests are consumed as dependencies and ran as part of this same suite.

Dockerized version

A dockerized version of CNF tests is available at quay.io/openshift-kni/cnf-tests. For more details on how to use it, please check the corresponding docs.

Example RAN profile

An example RAN profile is provided in feature-configs/cn-ran-overlays
