Upload your scenario in a config map

  • to load the scenario in a config map
  • to create a volume from the config map
  • to mount this volume in the container
  • to reference the file as a resource.

Create multiple pods to simulate multiple service task container

kubectl create configmap scenarii --from-file=$(root)/MyScenario.json -n $(namespace)

Start

cd k8s kubectl create -f pa-DiscoverySeedExtraction.yaml
