Running CPS via Helm charts on Minikube :

WSL Checks (when using WSL2 on MS Windows)

Check that your WSL 2 environment is running both linux distribution and docker using a windows command prompt/shell
*It might be needed to configure for Windows is configured for WSL 2 and WSL itself is set to use your linux distribution as default.

WSL Check

$ wsl -l -v
  NAME                   STATE           VERSION
* Ubuntu-20.04           Running         2
  docker-desktop         Running         2
  docker-desktop-data    Running         2

When using WSL 2ensure to open a WSL shell window ie. Command Prompt, wsl ...

Install MiniKube

Install and start MiniKube

Install and Start MiniKube

curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube start

Install Kubectl and Helm and Helm Repo

To setup kubectl and helm for ONAP locally follow steps as outlined in the deploy section on - https://docs.onap.org/projects/onap-oom/en/latest/oom_user_guide.html#deploy

Please note the following amendments to the above instructions:

Follow https://v1-18.docs.kubernetes.io/docs/tasks/tools/install-kubectl/ to install the latest version of kubectl instead of the very old 1.15.11.
No Need to 'Paste kubectl config rom Rancher' (not sure why that is even in those instructions)
Skip 'helm install ons/onap' as the document mentions it is not available anymore

Install helm push plugin (before building the Helm repository)

Install Helm Push Plugin

helm plugin install https://github.com/chartmuseum/helm-push.git --version=0.8.1

After following the steps above ensure your local repo has the charts loaded onto it :

helm search repo local
NAME CHART VERSION APP VERSION DESCRIPTION
local/a1policymanagement 8.0.0 1.0.0 A Helm chart for A1 Policy Management Service
local/aaf 8.0.0 ONAP Application Authorization Framework
local/aai 8.0.0 ONAP Active and Available Inventory
local/appc 8.0.0 Application Controller
...
local/contrib 8.0.0 ONAP optional tools
local/cps 8.0.0 Configuration Persistance Service (CPS)

Deploy CPS

To install CPS only, run the following command from within the oom/kubernetes/cps folder

Install CPS using Helm

cd <your git repo>/oom/kubernetes/cps
helm upgrade dev1 local/cps -i -f values.yaml --set global.masterPassword=mysecr

Once you chart is deployed, we can test it by hitting the spring actuator endpoint from a pod:

Test CPS is alive

kubectl run -it network-multitool-$USER --image=praqma/network-multitool --restart=Never --rm -- bash

curl -X GET "http://cps:8080/manage/health" -H "accept: application/json" -H "Content-Type: application/json"

Note. This was tested on windows using WSL2 with Ubuntu 20.04 but any similar environment should suffice.
