Pushing with authentication doesn't work with credsStore osxkeychain

[fakeh]

Trying to push a Maven built image to Docker Hub with the authentication details specified in ~/.docker/config.json (as created by docker login) doesn't pull in the correct credentials, resulting in:

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.13:push (push-image) on project publisher: Exception caught: denied: requested access to the resource is denied -> [Help 1]

Setting up the element in ~/.m2/settings.xml works as expected.

<groupId>com.spotify</groupId>
<artifactId>docker-maven-plugin</artifactId>
<version>0.4.13</version>

<execution>
	<id>push-image</id>
	<phase>deploy</phase>
	<goals>
		<goal>push</goal>
	</goals>
	<configuration>
		<imageName>redbite/${image.name}:${project.version}</imageName>
		<useConfigFile>true</useConfigFile>
	</configuration>
</execution>

$cat ~/.docker/config.json
{
	"auths": {
		"https://index.docker.io/v1/": {}
	},
	"credsStore": "osxkeychain"
}

see spotify/docker-client#657, support needs to be added to the underlying docker-client library

Any workaround or tag in maven to force the plugin to use creds mentioned in of pom.xml
