Kubernetes gives us a construct called ConfigMaps that helps us implement this feature. There's two ways to do this, either you can pass in data via environment variables for small sets of data or for larger pieces of data you can use it as a volume mount. In the simple scenario in this example I have a configmap a time configmap EPI version v1 and we're going to call it log-config and the actual data associated with this is log-level of debug. So this is the definition of the configmap now when we want to execute this in the container we first need to volume mount that, so we put volume of config-volume and configmap with name of log-config, which is the information that we had pulled in before. And to see this inside of the container, we're going to pass this in as an environment variable, we'll call it log-level and the value comes from…
