	Version     string `json:"version"`
	AppVersion  string `json:"app_version"`
	Description string `json:"description"`
}

type ChartLock

	Generated time.Time `json:"generated"`
	// Digest is a hash of the dependencies in Chart.yaml.
	Digest string `json:"digest"`

type Dependency

type Dependency struct {
	// Name is the name of the dependency.
	//
	// This must mach the name in the dependency's Chart.yaml.
	Name string `json:"name"`
	// Version is the version (range) of this chart.
	//
	// A lock file will always produce a single version, while a dependency
	// may contain a semantic version range.
	Version string `json:"version,omitempty"`
	// The URL to the repository.
	//
	// Appending `index.yaml` to this string should result in a URL that can be
	// used to fetch the repository index.
	Repository string `json:"repository"`
	// A yaml path that resolves to a boolean, used for enabling/disabling charts (e.g. subchart1.enabled )
	Condition string `json:"condition,omitempty"`
	// Tags can be used to group charts for enabling/disabling together
