)

chartsToCheckConstraints and *ChartsToCheckConstraints define which charts and system charts should be checked for images and added to imageSet based on whether the given Rancher version/tag satisfies the chart's Rancher version constraints to allow support for multiple version lines of a chart in airgap setups. If a chart is not defined here, only the latest version of it will be checked for images. INFO: CRD charts need to be added as well.

Functions

func BuildOrGetIndex

func BuildOrGetIndex(dir string) (*repo.IndexFile, error)

BuildOrGetIndex builds or get index from local chart repo directory

func DecodeValuesInDir

func DecodeValuesInDir(dir string) ([]map[interface{}]interface{}, error)

DecodeValuesInDir reads directory and returns a slice of values corresponding to values.yaml files found inside of it.

func DecodeValuesInTgz

func DecodeValuesInTgz(path string) ([]map[interface{}]interface{}, error)

DecodeValuesInTgz reads tarball and returns a slice of values corresponding to values.yaml files found inside of it.

func IsChartDir

func IsChartDir(dirName string) (bool, error)

IsChartDir validate a chart directory.

Checks for a valid Chart.yaml.

func LoadMetadata

func LoadMetadata(path string) (*chart.Metadata, error)

LoadMetadata loads chart metadata from chart directory (not tgz file)

func PickImagesFromValuesMap

func PickImagesFromValuesMap(
	imagesSet map[string]map[string]bool,
	values map[interface{}]interface{},
	chartSource string,
	OS OsType,
) error

PickImagesFromValuesMap walks a values map to find images, and add them to imagesSet.
