Kraken as a KubeApp

To run containerized Kraken as a Kubernetes/OpenShift Deployment, follow these steps:

1. Configure the config.yaml file according to your requirements.
2. Create a namespace under which you want to run the kraken pod using kubectl create ns <namespace>.
3. Switch to <namespace> namespace:
   • In Kubernetes, use kubectl config set-context --current --namespace=<namespace>
   • In OpenShift, use oc project <namespace>
4. Create a ConfigMap named kube-config using kubectl create configmap kube-config --from-file=<path_to_kubeconfig>
5. Create a ConfigMap named kraken-config using kubectl create configmap kraken-config --from-file=<path_to_kraken_config>
6. Create a ConfigMap named scenarios-config using kubectl create configmap scenarios-config --from-file=<path_to_scenarios_folder>
7. Create a serviceaccount to run the kraken pod kubectl create serviceaccount useroot.
8. In Openshift, add privileges to service account and execute oc adm policy add-scc-to-user privileged -z useroot.
9. Create a Deployment and a NodePort Service using kubectl apply -f kraken.yml

NOTE: It is not recommended to run Kraken internal to the cluster as the pod which is running Kraken might get disrupted.
