// with a porter.yaml file as an argument
var applyCmd = &cobra.Command{

	Short: "Applies a configuration to an application",
	Long: fmt.Sprintf(`
%s

Applies a configuration to an application by either creating a new one or updating an existing
one. For example:

  %s

This command will apply the configuration contained in porter.yaml to the requested project and
cluster either provided inside the porter.yaml file or through environment variables. Note that
environment variables will always take precendence over values specified in the porter.yaml file.

By default, this command expects to be run from a local git repository.

The following are the environment variables that can be used to set certain values while
applying a configuration:
  PORTER_CLUSTER              Cluster ID that contains the project
  PORTER_PROJECT              Project ID that contains the application
  PORTER_NAMESPACE            The Kubernetes namespace that the application belongs to
  PORTER_SOURCE_NAME          Name of the source Helm chart
  PORTER_SOURCE_REPO          The URL of the Helm charts registry
  PORTER_SOURCE_VERSION       The version of the Helm chart to use
  PORTER_TAG                  The Docker image tag to use (like the git commit hash)
