Getting Mac Docker client to connect to virtualbox via vagrant

Question

I am trying to expose dockers tcp ip to my host docker client. I have the following setup

• Virtualbox 4.3.26 r98988
• vagrant 1.7.2
• Mac OSX Mavericks 10.9.5
• Centos 6.6 vagrant box running (docker 1.5.0)
• Docker 1.5 on the host and vagrant box

FYI, I can get to the exposed docker containers just fine in the browser. I have exposed the necessary ports in the VagrantFile

in /etc/init.d/docker I have set other_args as the following:

other_args="--insecure-registry 192.168.254.96:5000 -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock"

I have set the following DOCKER_HOST=tcp://127.0.0.1:2375 on the host and I get the following error:

FATA[0076] An error occurred trying to connect: Get https://127.0.0.1:2375/v1.17/containers/json: EOF

If i set the DOCKER_HOST=tcp://172.17.8.101 then i get

FATA[0076] An error occurred trying to connect: Get https://127.0.0.1:2375/v1.17/containers/json: EOF I'm not able to run the usual docker ps from the host.

I tried running netstat -tulpn to see what the virtualbox/vagrant instance was listening to. It seems like 2375 is listening.

I tried looking at the virtual network settings for that instance

I have a few questions

1. Did I set the tcp connection correctly in /etc/init.d/docker. Should it be the ip that I set in vagrant?
2. Is there a way to check if the docker client is connecting with the mac host?

Answer 1

I ended up using https (https://docs.docker.com/articles/https/). After those steps were completed I needed to stop iptables service /etc/init.d/iptables stop.
