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 :

Install MiniKube and start it :

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

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

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

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.
