Bundler represents a key/certificate pair.

type Certs

type Certs struct {
	// contains filtered or unexported fields
}

Certs handles keys and certificates for kube components.

func NewCerts

func NewCerts(path string, r runner.Runner) (*Certs, error)

NewCerts returns a configured Certs.

func (*Certs) BundleFor

func (c *Certs) BundleFor(ctx context.Context, name string) (*Bundle, error)

BundleFor returns keys Bundle for a provided name of the kube component.

type ChartGetter

type ChartGetter interface {
	GetChart(ctx context.Context, repoName, chartName, chartVersion string) (*chart.Chart, error)
}

ChartGetter interface is a wrapper for GetChart function.

type Handler

type Handler struct {
	// contains filtered or unexported fields
}

Handler is a http controller for a kube entity.

func NewHandler

func NewHandler(

) *Handler

NewHandler constructs a Handler for kubes.

func (*Handler) Register

func (h *Handler) Register(r *mux.Router)

Register adds kube handlers to a router.

type Interface

type Interface interface {
	Create(ctx context.Context, k *model.Kube) error
