Follow the steps below Depending on you requirements there are several ways to setup the CPS environment. 

Checkout the project

Checkout https://gerrit.onap.org/r/admin/repos/cps

From docker-compose folder run the following after building the images locally :

VERSION=x.y.z-SNAPSHOT DB_HOST=dbpostgresql DB_USERNAME=cps DB_PASSWORD=cps docker-compose up -d

This starts both cps and postgres containers.

Note: Checkout the README.md in docker-compose folder for detailed steps.

Setup schema in DB

Liquibase auto creates the schema on startup.

Set environment variables with relevant connection details which can be found in application.yml in docker-compose folder.

Building the project

When building the project run from the root cps folder :

mvn clean install

Running the project

This option is if you have  a local postgres running.

From the cps folder run the following command :

java -DDB_HOST=localhost -DDB_USERNAME=cps -DDB_PASSWORD=cps -jar cps-application/target/cps-application-x.y.z-SNAPSHOT.jar

...

mvn spring-boot:run

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

Install 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 Help 

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:

• 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

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

Deploy CPS

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

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

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