Docker private registry : How to list all images

dep4b · September 16, 2016, 12:02pm

I’m adding support for DockerCloud to GrandCentrall.

It takes git hashes and looks for the corresponding docker images, and deploys them. I need to consult our private repo to see if a git hash has corresponding docker images or not, and ended up with this very very very awful hack:

github.com

o19s/grand_central/blob/docker_cloud/src/main/java/com/o19s/grandcentral/dockercloud/DockercloudRegistry.java#L40


	private CloseableHttpClient httpClient;
	private final JsonFactory jsonFactory = new JsonFactory();
	private final ObjectMapper jsonObjectMapper = new ObjectMapper(jsonFactory);


	public DockercloudRegistry(DockercloudConfiguration dockercloudConfiguration) {
		this.dockercloudConfiguration = dockercloudConfiguration;


		httpClient = HttpClients.createDefault();
	}


	@Override
	public boolean imageExistsInRegistry(String dockerTag) throws Exception {
		
		LOGGER.info("Checking if Docker tag exists in registry: " + dockerTag);
		
		boolean imageExists = false;


		String serviceName = "chk-" + dockerTag;


		String imageName = dockercloudConfiguration.getStackExistsTestImage() + ":" + dockerTag;

Yep. I basically create a service, see if it starts up successfully, and then if it does, it exists. If it doesn’t, then it doesn’t exist. Ugh. I spent hours trying to make a crawler to hit the docker cloud website… the react front end defeated me!
