type ApplicationConfig 

type ApplicationConfig struct {
	// The RoleName key inserted as an annotation (https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/)
	// in Flyte Workflow CRDs created in the CreateExecution flow. The corresponding role value is defined in the
	// launch plan that is used to create the execution.

	ID     string  `json:"id"`

}

type ClusterResourceConfig 

type ClusterResourceConfig struct {
	TemplatePath string `json:"templatePath"`
	// TemplateData maps template keys e.g. my_super_secret_password to a data source
	// which is then substituted in cluster resource templated config files wherever
	// {{ my_super_secret_password }} appears.
	TemplateData    TemplateData    `json:"templateData"`
	RefreshInterval config.Duration `json:"refreshInterval"`
	// Like TemplateData above, this also specifies template values as defaults to be substituted for specific domains
	// or for all domains.
	// For example:
	/*
		defaultData:
		  production:
		    foo:
		      value: "bar"
		    foofoo:
		      valueFrom:
		        env: SHELL

	// The database user who is connecting to the server.
	User string `json:"username"`
	// Either Password or PasswordPath must be set.
	// The Password resolves to the database password.
	Password     string `json:"password"`
	PasswordPath string `json:"passwordPath"`
	// See http://gorm.io/docs/connecting_to_the_database.html for available options passed, in addition to the above.
	ExtraOptions string `json:"options"`
}

This configuration section is used to for initiating the database connection with the store that holds registered entities (e.g. workflows, tasks, launch plans...) This struct specifically maps to the flyteadmin config yaml structure.

type Domain
