Functions

func DeployVersion

func DeployVersion(appID string, sequence int64) error

DeployVersion deploys the version for the given sequence

func ExtractArchiveToTempDirectory

func ExtractArchiveToTempDirectory(archiveFilename string) (string, error)

func GetForwardedPortsFromAppSpec

func GetForwardedPortsFromAppSpec(appID string, sequence int64) ([]types.ForwardedPort, error)

func GetGraphs

func GetGraphs(app *types.App, sequence int64, kotsStore store.Store) ([]kotsv1beta1.MetricGraph, error)
