The client is structured similarly to the docker command line client, such that. This can be a unix socket (e.g., unix:///var/run/docker.sock) on macOS/Linux,.
At the moment runs only on Linux. On OSX you have to setup a VM with Linux installed on it in order to use it. The most popular approach is by using but this VirtualBox abstraction seems heavy.
There is another, more lightweight way of interacting with a VM on OSX using great project. It spins up a small Linux distribution (called ) which runs from RAM, weights around 24 MB and boots in 5-6 seconds. In this article I’ll guide through all necessary steps to create more lightweight Docker experience on OSX.
Install Docker client build for OSX curl -o docker chmod +x./docker mv docker /bin export DOCKERHOST=localhost docker version Client version: 0.7.6 Go version (client): go1.2 Git commit (client): bc3b2ec 2014/02/05 16:19:18 dial unix /var/run/docker.sock: no such file or directory We are getting an error because there is no Docker daemon listening on the socket. We will fix that in a moment by using the daemon that sits on the VM. Install boot2docker curl boot2docker chmod a+x boot2docker mv boot2docker /bin/boot2docker Initialize the VM and then start it boot2docker init 2014-02-01 16:22:12 Creating VM boot2docker-vm.
Boot2docker up 2014-02-01 16:22:52 Starting boot2docker-vm. 2014-02-01 16:23:12 Started.

Check if you can ssh into it (password is tcuser) boot2docker ssh Export DOCKERHOST as localhost so local Docker OSX client can communicate with the socket on the VM export DOCKERHOST=localhost Run docker version to check if it works. Docker version Client version: 0.7.6 Go version (client): go1.2 Git commit (client): bc3b2ec Server version: 0.7.6 Git commit (server): bc3b2ec Go version (server): go1.2 Let’s pull our first image and try to run it docker pull zaiste/postgresql Pulling repository zaiste/postgresql docker run -d zaiste/postgresql docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES daffafef1a96 zaiste/postgresql:latest /bin/su postgres -c 14 minutes ago Up About a minute 0.0.0.0:5432/tcp insaneturing You can also build a Docker client yourself. For that you will need installed on your system. For OSX the easiest way is to get it using. Brew install go go get -v github.com/dotcloud/docker/docker.
Mv tmp/bin/docker /bin/ Hopefully, those steps will make your interactions with Docker on OSX simpler and more productive.
Final DockerClient client = DefaultDockerClient.builder.uri( 'unix:///var/run/docker.sock ').build; client.ping What do you expect The client will connect to docker via the unix socket. The ping will return successfully. What happened instead The ping fails with an exception. See stack trace below. Software:.

On my mac I use docker-machine and connect on a TCP socket.
Are you using docker for mac? Yes, this occurs using docker for mac and connecting over a unix socket. (And, side note, docker for mac cannot be configured to use TCP.
If you try to set the hosts option in the settings json, it conflicts with the -hosts option hard-coded into the docker command line options in the xhyve VM. Not particularly relevant, but I wanted to kvetch about it.) When I create a docker-machine VM and connect over TCP, everything runs fine.
But I would think that isn't surprising. The jnr changes were about the code for unix socket connections. Nothing about the TCP connections should be impacted.
