docker version fails on OS X

Question

I have a fresh, first-time install of boot2docker on OS X 10.10.4 and I am getting the following error:

$ boot2docker version
Boot2Docker-cli version: v1.7.1
Git commit: 8fdc6f5

$ docker version
Client version: 1.7.1
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 786b29d
OS/Arch (client): darwin/amd64
An error occurred trying to connect: Get https://192.168.59.103:2376/v1.19/version: dial tcp 192.168.59.103:2376: i/o timeout

Everything I read says this problem was fixed in 1.7.1 of boot2docker... what am I missing?

Update 1 Upon a suggestion below I tried a few things. Here's the output:

$ boot2docker ip
192.168.59.103
$ openssl s_client -connect 192.168.59.103:2376
^C  <--- I gave up after a while... nothing was responding.
$ boot2docker ssh

Update 2 Should have rebooted... not used to caring about that when not in Windows but it seems something on my Mac had gotten out of whack... now it works.

Answer 1

Please try eval $(boot2docker shellinit) and issue docker version again.

If that doesn´t help, please try openssl s_client -connect 192.168.59.103:2376 to see there is something listening on 192.168.59.103:2376

If there is nothing listening, then your docker version tries to connect to the wrong address and you have to set your Variable DOCKER_HOST to the right address.

You could also check with boot2docker ssh if boot2docker is up and with boot2docker ip to which ip boot2docker is bound (should be 192.168.59.103).

Answer 2

Sadly, I should have done troubleshooting step 1: reboot. For whatever reason, that fixed it.
