docker-java equivalent of "docker service create --with-registry-auth"

Question

Using https://github.com/docker-java/docker-java and looking for a way to add the --with-registry-auth option from https://docs.docker.com/v17.12/engine/reference/commandline/service_create/#options

val createCmd = dockerClient.createServiceCmd(
                ServiceSpec()
                        .withName("name")

                        .withTaskTemplate(TaskSpec()
                                .withContainerSpec(ContainerSpec()
                                        .withEnv(envs)
                                        .withImage("image")
                                        .withMounts(mounts)
                                )
                                .withNetworks(networks)
                                .withPlacement(ServicePlacement()
                                        .withConstraints(constraints))
                        )
        )

To clarify this more:

I am looking for docker-java way to do this command (this does work!):

docker service create --with-registry-auth --constraint 'node.labels.mynodeid==7' myprivateregistry.foo:5000/imagename:latest

Removing the --with-registry-auth like this

docker service create --constraint 'node.labels.mynodeid==7' myprivateregistry.foo:5000/imagename:latest

will bringt up this error: No such image: myprivateregistry.foo:5000/imagename:latest because the credentials, which are valid btw, are not passed to the node.

I don't get any error. I just don't know how to use the docker-java API to add the mentioned flag. Did search doc and source code but did not find anything. — TomGrill Games

Is it fine if the registry auth is provided in your dockerClient object itself? — mchawre

Building DockerClient object with .withRegistryUsername(), .withRegistryPassword() did not change anything. — TomGrill Games

What was the poblem with these two options, or you just got no output. — mchawre

As of docker-java 3.2.0-rc5 you can now specify authConfig to pull images from a private registry

        AuthConfig authConfig = new AuthConfig()
                .withUsername("testuser")
                .withPassword("testpassword")
                .withEmail("[email protected]")
                .withRegistryAddress("your.registry.address.here");

        dockerClient.createServiceCmd(new ServiceSpec()
                .withName(SERVICE_NAME)
                .withTaskTemplate(new TaskSpec()
                        .withContainerSpec(new ContainerSpec()
                                .withImage(DEFAULT_IMAGE))))
                .withAuthConfig(authConfig)
                .exec();

Specify registry auth details in dockerClient object itself in your code.

Check this out.

If it didn't worked. First verify whether the registry auth details you have are the correct one and manually try to pull docker image using docker cli.

Put registry config in .docker/config.json file and try to pull docker images. And then backtrace the issues.

Thanks, docker cli works, see question. I think either docker-java does not provide a way to pass the option/flag or I cannot find how.
