Package gcp_credentials contains implementations of DockerConfigProvider for Google Cloud Platform.

MakeDockerKeyring inspects the passedSecrets to see if they contain any DockerConfig secrets.

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

RegisterCredentialProvider is called by provider implementations on initialization to register themselves, like so: func init() { RegisterCredentialProvider("name", &myProvider{...}) }.

BasicDockerKeyring is a trivial map-backed implementation of DockerKeyring.

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

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

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

DockerKeyring tracks a set of docker registry credentials, maintaining a reverse index across the registry endpoints.

DockerConfig represents the config file used by the docker CLI.
