Functions

func InstallCmd

func InstallCmd(opts *options.Options, optionsFunc ...cliutils.OptionsFunc) *cobra.Command

func LabelsToFlagString

func LabelsToFlagString(labelMap map[string]string) string

func NewCLISettings

func NewCLISettings(namespace, context string) *cli.EnvSettings

Build a Helm EnvSettings struct basically, abstracted cli.New() into our own function call because of the weirdness described in the big comment below

func RenderKnativeManifests

func RenderKnativeManifests(opts options.Knative) (string, error)

used by e2e test

func RenderKnativeValues

func RenderKnativeValues(version string) (string, error)

func Uninstall

func Uninstall(opts *options.Options, cli install.KubeCli, mode Mode) error

func UninstallCmd

func UninstallCmd(opts *options.Options, optionsFunc ...cliutils.OptionsFunc) *cobra.Command

Types

type HelmClient

type HelmClient interface {
	// Prepare an installation object that can then be .Run() with a chart object
	NewInstall(namespace, releaseName string, dryRun bool, context string) (HelmInstallation, *cli.EnvSettings, error)

	// Prepare an un-installation object that can then be .Run() with a release name
	NewUninstall(namespace string) (HelmUninstallation, error)

	// List the already-existing releases in the given namespace
	ReleaseList(namespace string) (HelmReleaseListRunner, error)

	// Returns the Helm chart archive located at the given URI (can be either an http(s) address or a file path)
	DownloadChart(chartArchiveUri string) (*chart.Chart, error)

	// Returns true if the release with the given name exists in the given namespace
	ReleaseExists(namespace, releaseName string) (releaseExists bool, err error)
}

This interface implements the Helm CLI actions. The implementation relies on the Helm 3 libraries.

func DefaultHelmClient

func DefaultHelmClient() HelmClient

a HelmClient that talks to the kube api server and creates resources

type HelmInstallation

type HelmInstallation interface {
	Run(chrt *chart.Chart, vals map[string]interface{}) (*release.Release, error)
}

an interface around Helm's action.Install struct

type HelmReleaseListRunner

type HelmReleaseListRunner interface {
	Run() ([]*release.Release, error)
	SetFilter(filter string)
}

an interface around Helm's action.List struct

type HelmUninstallation

type HelmUninstallation interface {
	Run(name string) (*release.UninstallReleaseResponse, error)
}

an interface around Helm's action.Uninstall struct

type Installer

type Installer interface {
	Install(installerConfig *InstallerConfig) error
}

func NewInstaller

func NewInstaller(opts *options.Options, helmClient HelmClient) Installer

NewInstaller consumes a helm client and sets up an installer for usage in glooctl.

func NewInstallerWithWriter

func NewInstallerWithWriter(helmClient HelmClient, kubeNsClient v1.NamespaceInterface, outputWriter io.Writer) Installer

NewInstallerWithWriter creates a new Installer for a given helm client, namespace and output writer. The extra variables are exposed to allow for ease of testing.

}

type Mode

type Mode int

const (
	Gloo Mode = iota
	GlooWithUI
	Enterprise
	Federation
)

type Uninstaller

type Uninstaller interface {
	Uninstall(ctx context.Context, cliArgs *options.HelmUninstall, mode Mode) error
}
