This commit switches the object type from Deployment to Job to be able to display the status after executing all the scenarios specified in the Kraken config instead of crashing which is expected in Deployments. Fixes https://github.com/cloud-bulldozer/kraken/issues/135

### Kraken image
|
|
|
|
Container image gets automatically built by quay.io at [Kraken image](https://quay.io/repository/openshift-scale/kraken).
|
|
|
|
### Run containerized version
|
|
Refer [instructions](https://github.com/cloud-bulldozer/kraken/blob/master/docs/installation.md#run-containerized-version) for information on how to run the containerized version of kraken.

### Run Custom Kraken Image
|
|
Refer to [instructions](https://github.com/cloud-bulldozer/kraken/blob/master/containers/build_own_image-README.md) for information on how to run a custom containerized version of kraken using podman
|

### Kraken as a KubeApp
|
|
|
|
To run containerized Kraken as a Kubernetes/OpenShift Deployment, follow these steps:
|
|
1. Configure the [config.yaml](https://github.com/openshift-scale/kraken/tree/master/config/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 Job using `kubectl apply -f kraken.yml` and monitor the status using `oc get jobs` and `oc get pods`.
|
|
|
|
NOTE: It is not recommended to run Kraken internal to the cluster as the pod which is running Kraken might get disrupted.
