# Installation and Configuration There are two ways we can run this utility. In kubernetes as services and as ad-hoc. ## Installing in Kubernetes as services Deploying in Kubernetes itself which will run periodically (every 15 minutes by default) and capture unused resources and expose them as Prometheus metrics. You should configure prometheus or similar tool to scrape this metrics  Once you have all The metrics in prometheus you can configure prometheus rule to trigger alert. Sample alert are provided in deploy folder deploy/prometheusrule.yaml(./deploy/prometheusrule.yaml) And you can import k8sPurger Dashboard from deploy folder to create dashbaord like below.  NOTE :- Service will scan for unused resources every 15 minutes which you can changing by setting REFRESH_INTERVAL(in second) in deployment.yaml ``` git clone https://github.com/yogeshkk/K8sPurger cd K8sPurger kubectl apply -f deploy/manifest.yaml ``` ## Running From shell Second way is to run as ad-hoc command as and when required. You can run this manually it required [Python client for Kuberntes](https://github.com/kubernetes-client/python). We need to install that first also make sure you have kubeconfig in ~/.kube/conf or in KUBECONFIG env variable before runing script. ``` pip3 install -r requirements.txt python K8sPurger.py ``` Output Will look like below ``` yogesh$ ~/p/K8sPurger> python K8sPurger.py This script is created to find unused resource in Kubernetes.
