Matt Moore 0c5d9ed0d2 Implements a credentialprovider library for use by DockerPuller. ... This change refactors the way Kubelet's DockerPuller handles the docker config credentials to utilize a new credentialprovider library. The credentialprovider library is based on several of the files from the Kubelet's dockertools directory, but supports a new pluggable model for retrieving a .dockercfg-compatible JSON blob with credentials. With this change, the Kubelet will lazily ask for the docker config from a set of DockerConfigProvider extensions each time it needs a credential. This change provides common implementations of DockerConfigProvider for: - "Default": load .dockercfg from disk - "Caching": wraps another provider in a cache that expires after a pre-specified lifetime. GCP-only: - "google-dockercfg": reads a .dockercfg from a GCE instance's metadata - "google-dockercfg-url": reads a .dockercfg from a URL specified in a GCE instance's metadata. - "google-container-registry": reads an access token from GCE metadata into a password field.		2014-11-17 21:46:54 -08:00
