Support for Docker for Mac #115

Open bijoys opened 8 years ago

bijoys commented 8 years ago

This plugin is failing to build images when used with Docker for Mac. The error is 'java.net.ConnectException: Connection refused'. DOCKER_HOST is set to unix:///var/run/docker.sock

Is there a way to get the plugin working for Docker for Mac?

thanks.

+1, I was able to build an image using Docker for Mac using the spotify docker maven plugin

wouterd commented 8 years ago

Hmm, interesting. I have docker or mac as well, but it doesn't set the DOCKER_HOST environment variable and thus my plugin just works. Try it by doing unset DOCKER_HOST before running the maven build. Docker 4 mac exposes the socket as well as an http interface to the docker daemon on localhost, so the default behaviour of my plugin (connecting to http on localhost) should do. Support for unix domain sockets is something I'd love to have, but it's rather hard on the JVM to get it to work. Also, I'd have to figure out how to change the transport of my http client from tcp to unix sockets, which isn't all that trivial. :)

Thanks for the response. I did not have DOCKER_HOST env variable set when I tested this. My docker command line is working fine, but the plugin fails with connection refused. Please see the stack trace below. Is there anything I can do to troubleshoot this further?

@wouterd its not so super difficult, all you need to todo is to use a different ConnectionSocketFactory for unix sockets like it is done here for Apache HttpClient.

I first thought, too, that it is too difficult, but its astonishingly easy (Spotify does it quite similarly).

And btw, Docker for Mac over Unix sockets works really nice.

bijoys commented 8 years ago

@wouterd would you be able to integrate the changes suggested by @rhuss? Thanks.

udalrich commented 8 years ago

I am running Docker 1.12 and it does not seem to be opening the socket at 2375.

$ telnet localhost 2375 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused Trying ::1... telnet: connect to address ::1: Connection refused telnet: Unable to connect to remote host $ docker --version Docker version 1.12.0-rc3, build 91e29e8, experimental $ echo $DOCKER_HOST

(That is an empty line as the echo output).
