docker-machine安装由于“无法读取CA证书”错误而失败

Question

I am trying to setup docker-machine locally on my Windows machine and I followed the install instructions at the Docker Machine Page .

Per the instructions, I ran the following commands in my bash terminal

To install Docker client binary

$curl -L https://github.com/docker/machine/releases/download/v0.3.0/docker-machine_windows-amd64.exe > /bin/docker-machine

and to install Docker machine binary

$ curl -L https://github.com/docker/machine/releases/download/v0.3.0/docker-machine_windows-amd64.exe > /bin/docker-machine

when I try to run docker-machine -v I get the following error

FATAL[0000] Couldn't read ca cert 'C:\\Users\\Me\\.boot2docker\\certs\\boot2doker-vm\\ca.pm: open 'C:\\Users\\Me\\.boot2docker\\certs\\boot2docker-vm'\\ca.pem: The filename, directory name, or volume label syntax is incorrect.

I did some searching and came across a few posts, but can't really see any connection to what would be causing my issues...

Answer 1

I installed docker machine today on my Windows 7 machine and run the command without any problem.

Did you use boot2docker before on your machine? If you did, it might be related as mine is a clean machine without any pre-existing docker installations.

Answer 2

Its referring to boot2docker environment.

see this: DOCKER_CERT_PATH="/Users//.docker/machine/machines/dev"

Answer 3

I got the same answer and was able to resolve it by changing the path pattern to be unix-style in the environment variable.

Inside msysgit bash shell:

export DOCKER_CERT_PATH=/C/Users/Me/.boot2docker/certs/boot2docker-vm

This resolved boot2docker.

Note that I also tried using docker-machine before using boot2docker which previously failed with the same error. That was not resolved the same way boot2docker could be resolved. For now only boot2docker is working for me.
