)
Functions ¶
func GetGCPOauthToken ¶
func ImageCredsWithDefaults ¶
func ImageCredsWithDefaults(lookup func() ImageCreds, configPath string) (func() ImageCreds, error)
Types ¶
type Client ¶
type Client interface {
Tags(context.Context) ([]string, error)
Manifest(ctx context.Context, ref string) (ImageEntry, error)
}
Client is a remote registry client for a particular image repository (e.g., for quay.io/weaveworks/flux). It is an interface so we can wrap it in instrumentation, write fake implementations, and so on.
func NewInstrumentedClient ¶
type ClientFactory ¶
type ClientFactory interface {
ClientFor(image.CanonicalName, Credentials) (Client, error)
}
ClientFactory supplies Client implementations for a given repo, with credentials. This is an interface so we can provide fake implementations.
type Credentials ¶
type Credentials struct {
// contains filtered or unexported fields
}
Credentials to a (Docker) registry.
func NoCredentials ¶
func NoCredentials() Credentials
NoCredentials returns a usable but empty credentials object.
func ParseCredentials ¶
func ParseCredentials(from string, b []byte) (Credentials, error)
func (Credentials) Hosts ¶
func (cs Credentials) Hosts() []string
Hosts returns all of the hosts available in these credentials.
func (Credentials) Merge ¶
func (cs Credentials) Merge(c Credentials)
func (Credentials) String ¶
func (cs Credentials) String() string
type ImageCreds ¶
type ImageCreds map[image.Name]Credentials
ImageCreds is a record of which images need which credentials, which is supplied to us (probably by interrogating the cluster)
type ImageEntry ¶
type Registry ¶
type Registry interface {
GetRepositoryImages(image.Name) ([]image.Info, error)
GetImage(image.Ref) (image.Info, error)
}
Registry is a store of image metadata.
func NewInstrumentedRegistry ¶
type Remote ¶
type Remote struct {
// contains filtered or unexported fields
}
type RemoteClientFactory ¶
type RemoteClientFactory struct {
Logger log.Logger
Limiters *middleware.RateLimiters
Trace bool
InsecureHosts []string
// contains filtered or unexported fields
}
func (*RemoteClientFactory) ClientFor ¶
func (f *RemoteClientFactory) ClientFor(repo image.CanonicalName, creds Credentials) (Client, error)
