Status

• Generator container:
• Workload container:

                 [-n NAMESPACE] [--oc OC] [--ocs-namespace OCS_NAMESPACE]
                 [-s STORAGECLASS] [-t RUNTIME] [-z]

optional arguments:
  -h, --help            show this help message and exit
  -l LOG_DIR, --log-dir LOG_DIR
                        Path to use for log files
  -m {ReadWriteOnce,ReadWriteMany}, --accessmode {ReadWriteOnce,ReadWriteMany}
                        StorageClassName for the workload's PVCs
  -n NAMESPACE, --namespace NAMESPACE
                        Namespace to use for the workload
  --oc OC               Path/executable for the oc command

  -z, --sleep-on-error  On error, sleep forever instead of exit
  -t, --runtime         Run time in seconds

Deployment via the Helm chart (using Helm v3):

$ KUBECONFIG=~/src/osio4/kubeconfig helm install foo helm/ocs-monkey-generator
NAME: foo
