Package com.spotify.docker.client

Class DefaultDockerClient.CreateProgressHandler

java.lang.Object

com.spotify.docker.client.DefaultDockerClient.CreateProgressHandler

All Implemented Interfaces:

ProgressHandler

Enclosing class:

DefaultDockerClient

private static class DefaultDockerClient.CreateProgressHandler
extends Object
implements ProgressHandler

Hack: this ProgressHandler is meant to capture the image ID (or image digest in Docker 1.10+) of an image being created. Weirdly enough, Docker returns the ID or digest of a newly created image in the status of a progress message.

The image ID/digest is required to tag the just loaded image since, also weirdly enough, the pull operation with the fromSrc parameter does not support the tag parameter. By retrieving the ID/digest, the image can be tagged with its image name, given its ID/digest.
