Hi,

I am using docker tools and I am working on MacOS. I think that there is no way to configure docker-java to connect with an specific docker-machine. Is it right?

The reason is because in order to access to unix:///var/run/docker.sock I need to be inside the boot2docker (docker-machine ssh default) and to connect the URLs begins with tcp and this protocol is not supported.

Could you tell me if I am right? Otherwise, is there any work arround?

Regards,

Raquel

You can use http/https protocal to connect to a remote docker daemon. See https://github.com/docker-java/docker-java#programmatic

Hope that helps.

I have tried with http and https, but it does not work.

My code:

DockerClientConfig.DockerClientConfigBuilder builderD = DockerClientConfig

.createDefaultConfigBuilder().withUri("https://192.168.99.100:2376");

DockerClient docker = DockerClientBuilder

.getInstance(builderD)

.build();

ListContainersCmd cmd = docker.listContainersCmd();

List<Container> list = cmd.exec();

for (Container container : list) {

System.out.println(container.getImage());

}

With http the system reports that it can't read the response:
