Error building windows gems on OS X

[jdantonio]

Every time I try to build concurrent-ruby I have the same issue. Below are the full details.

I only use docker for building concurrent-ruby releases so I haven't done anything with my config since the last release. When I ran the build task I got this error:

Started.

To connect the Docker client to the Docker daemon, please set:
    export DOCKER_TLS_VERIFY=1
    export DOCKER_HOST=tcp://192.168.59.103:2376
    export DOCKER_CERT_PATH=/Users/Jerry/.boot2docker/certs/boot2docker-vm

Using above environment variables for starting rake-compiler-dock.

I set the requested environment variables and ran it again. Then I got this error:

rake-compiler-dock bash -c "      bundle --without=\"development testing\" &&\n      rake cross native gem RUBY_CC_VERSION=1.9.3:2.0.0:2.1.6:2.2.2\n      rm -rf .bundle\n"

Your environment variables are already set correctly.

boot2docker is installed and started, but 'docker version' failed.

    Please check why 'docker version' fails.
    You might need to re-init with 'boot2docker delete'
    or have a look at the FAQs: http://git.io/vtDBH

I dug into the code and added puts @docker_version_text into DockerCheck and got this output:

Client version: 1.7.0
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 0baf609
OS/Arch (client): darwin/amd64
An error occurred trying to connect: Get https://192.168.59.103:2376/v1.19/version: x509: certificate is valid for 127.0.0.1, 10.0.2.15, not 192.168.59.103

I tried both of the following environment exports but still no luck:

export DOCKER_HOST=tcp://127.0.0.1:2376
export DOCKER_HOST=tcp://10.0.2.15:2376

I then opened a new terminal and ran the following commands to cleanup docker:

boot2docker stop
boot2docker delete
boot2docker init
boot2docker start

I then tried the build task again (in the new terminal):

Waiting for VM and Docker daemon to start...

    export DOCKER_CERT_PATH=/Users/Jerry/.boot2docker/certs/boot2docker-vm
    export DOCKER_TLS_VERIFY=1

I set the requested environment variables and waited as boot2docker downloaded everything again. Once the download was complete the build tasks ran successfully.

Here is the info on my Mac:

Thanks for the detailed bug report! This is almost certainly caused by a bug in boot2docker-1.7.0. It is fixed in the iso-image, that comes with 1.7.1: https://github.com/boot2docker/boot2docker/issues/938

Try boot2docker upgrade or similar.

As a side note: The manual setup of environment variables is usually not necessary, but automatically done by rake-compiler-dock for each call.

[jdantonio]

I upgraded all involved components (docker, boot2docker, and VirtualBox) and had the same issue. I again ran the stop/delete/init/start sequence and everything worked afterwards.

$ docker version

@jdantonio rake-compiler-dock has docker-machine support in the meantime, so maybe things changed a bit. Do you still facing issues, or can I close this?

[jdantonio]

We can close it for now. I will be releasing c-r 1.0.1 within the next couple of weeks. I'll upgrade to the latest versions of everything and see how it goes. If there are problems I'll let you know.
