Deciphering Skaffold's configuration with skaffold.yaml

Any action that Skaffold needs to perform should be clearly defined in the skaffold.yaml configuration file. In this configuration file, you must specify which tool Skaffold has to use to build an image and then deploy it to the Kubernetes cluster. Skaffold typically expects to find the configuration file as skaffold.yaml in the current directory; however, we can override the location using the --filename flag.
