func RegisterCredentialProvider

func RegisterCredentialProvider(name string, provider DockerConfigProvider)

RegisterCredentialProvider is called by provider implementations on initialization to register themselves, like so:

func init() {
 	RegisterCredentialProvider("name", &myProvider{...})

func SetPreferredDockercfgPath added in v0.10.0

func SetPreferredDockercfgPath(path string)


type AuthConfig added in v1.13.0

type AuthConfig struct {
	Username string `json:"username,omitempty"`
	Password string `json:"password,omitempty"`
	Auth     string `json:"auth,omitempty"`

	// Email is an optional value associated with the username.
	// This field is deprecated and will be removed in a later
	// version of docker.
	Email string `json:"email,omitempty"`

	ServerAddress string `json:"serveraddress,omitempty"`

	// IdentityToken is used to authenticate the user and get
	// an access token for the registry.
	IdentityToken string `json:"identitytoken,omitempty"`

	// RegistryToken is a bearer token to be sent to a registry
	RegistryToken string `json:"registrytoken,omitempty"`

AuthConfig contains authorization information for connecting to a Registry This type mirrors ""

func LazyProvide added in v1.3.0

func LazyProvide(creds LazyAuthConfiguration) AuthConfig

type BasicDockerKeyring

type BasicDockerKeyring struct {
	// contains filtered or unexported fields

BasicDockerKeyring is a trivial map-backed implementation of DockerKeyring

func (*BasicDockerKeyring) Add

func (dk *BasicDockerKeyring) Add(cfg DockerConfig)

func (*BasicDockerKeyring) Lookup

func (dk *BasicDockerKeyring) Lookup(image string) ([]LazyAuthConfiguration, bool)

Lookup implements the DockerKeyring method for fetching credentials based on image name. Multiple credentials may be returned if there are multiple potentially valid credentials available. This allows for rotation.

type CachingDockerConfigProvider

type CachingDockerConfigProvider struct {
	Provider DockerConfigProvider
	Lifetime time.Duration
	// contains filtered or unexported fields

CachingDockerConfigProvider implements DockerConfigProvider by composing with another DockerConfigProvider and caching the DockerConfig it provides for a pre-specified lifetime.

func (*CachingDockerConfigProvider) Enabled

func (d *CachingDockerConfigProvider) Enabled() bool

Enabled implements dockerConfigProvider

func (*CachingDockerConfigProvider) LazyProvide added in v1.3.0

LazyProvide implements dockerConfigProvider. Should never be called.

func (*CachingDockerConfigProvider) Provide

Provide implements dockerConfigProvider

type DockerConfig

type DockerConfig map[string]DockerConfigEntry

DockerConfig represents the config file used by the docker CLI. This config that represents the credentials that should be used when pulling images from specific image repositories.

func ReadDockerConfigFile

func ReadDockerConfigFile() (cfg DockerConfig, err error)

func ReadDockerConfigFileFromUrl

func ReadDockerConfigFileFromUrl(url string, client *http.Client, header *http.Header) (cfg DockerConfig, err error)

func ReadDockerConfigJSONFile added in v1.5.0

func ReadDockerConfigJSONFile(searchPaths []string) (cfg DockerConfig, err error)

ReadDockerConfigJSONFile attempts to read a docker config.json file from the given paths. if searchPaths is empty, the default paths are used.

func ReadDockercfgFile added in v1.5.0

func ReadDockercfgFile(searchPaths []string) (cfg DockerConfig, err error)

ReadDockercfgFile attempts to read a legacy dockercfg file from the given paths. if searchPaths is empty, the default paths are used.

func ReadSpecificDockerConfigJsonFile added in v1.6.0

func ReadSpecificDockerConfigJsonFile(filePath string) (cfg DockerConfig, err error)

ReadSpecificDockerConfigJsonFile attempts to read docker configJSON from a given file path.

type DockerConfigEntry

type DockerConfigEntry struct {
	Username string
	Password string
	Email    string
	Provider DockerConfigProvider

func (DockerConfigEntry) MarshalJSON added in v0.19.0

func (ident DockerConfigEntry) MarshalJSON() ([]byte, error)

func (*DockerConfigEntry) UnmarshalJSON

func (ident *DockerConfigEntry) UnmarshalJSON(data []byte) error

type DockerConfigJson added in v1.1.0

type DockerConfigJson struct {
	Auths DockerConfig `json:"auths"`
	// +optional
	HttpHeaders map[string]string `json:"HttpHeaders,omitempty"`

DockerConfigJson represents ~/.docker/config.json file info see

type DockerConfigProvider

type DockerConfigProvider interface {
	// Enabled returns true if the config provider is enabled.
	// Implementations can be blocking - e.g. metadata server unavailable.
	Enabled() bool
	// Provide returns docker configuration.
	// Implementations can be blocking - e.g. metadata server unavailable.
	Provide() DockerConfig
	// LazyProvide() gets called after URL matches have been performed, so the
	// location used as the key in DockerConfig would be redundant.
	LazyProvide() *DockerConfigEntry

DockerConfigProvider is the interface that registered extensions implement to materialize 'dockercfg' credentials.

type DockerKeyring

type DockerKeyring interface {
	Lookup(image string) ([]LazyAuthConfiguration, bool)

DockerKeyring tracks a set of docker registry credentials, maintaining a reverse index across the registry endpoints. A registry endpoint is made up of a host (e.g., but it may also contain a path (e.g. This index is important for two reasons: - registry endpoints may overlap, and when this happens we must find the

most specific match for a given image

- iterating a map does not yield predictable results

func NewDockerKeyring

func NewDockerKeyring() DockerKeyring

NewDockerKeyring creates a DockerKeyring to use for resolving credentials, which lazily draws from the set of registered credential providers.

type FakeKeyring added in v0.11.0

type FakeKeyring struct {
	// contains filtered or unexported fields

func (*FakeKeyring) Lookup added in v0.11.0

func (f *FakeKeyring) Lookup(image string) ([]LazyAuthConfiguration, bool)

type HttpError added in v0.7.0

type HttpError struct {
	StatusCode int
	Url        string

HttpError wraps a non-StatusOK error code as an error.

func (*HttpError) Error added in v0.7.0

func (he *HttpError) Error() string

Error implements error

type LazyAuthConfiguration added in v1.3.0

type LazyAuthConfiguration struct {
	Provider DockerConfigProvider

LazyAuthConfiguration wraps dockertypes.AuthConfig, potentially deferring its binding. If Provider is non-nil, it will be used to obtain new credentials by calling LazyProvide() on it.

func DockerConfigEntryToLazyAuthConfiguration added in v1.3.0

func DockerConfigEntryToLazyAuthConfiguration(ident DockerConfigEntry) LazyAuthConfiguration

type UnionDockerKeyring added in v1.10.0

type UnionDockerKeyring []DockerKeyring

UnionDockerKeyring delegates to a set of keyrings.

func (UnionDockerKeyring) Lookup added in v1.10.0

func (k UnionDockerKeyring) Lookup(image string) ([]LazyAuthConfiguration, bool)
