有问题我的码头设置？
当我做一个 docker pull busybox 时，它会提取图像并下载完成。
bash-3.2 $ docker pull busybox

你好医生
我错过了什么？
您不需要当您使用 boot2docker 作为每个命令传递到
你看到呃当您以 sudo 运行时，因为 sudo 没有 DOCKER_HOST env set，只有您的用户可以。
您可以通过执行以下操作来确认：
$ env
然后一个
$ sudo env
在每个输出中寻找 DOCKER_HOST 。
至于有一个运行你的脚本的docker文件，为您工作：
Dockerfile
FROM busybox
＃将您的脚本复制到docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh
＃运行脚本
CMD /usr/local/bin/script.sh
然后你可以运行：
docker build -t your-image-name：your-tag。
这将构建您的码头图像，您可以通过执行以下操作查看：
docker image
然后运行您的容器，您可以执行以下操作：
docker运行your-image-name：your-tag
此运行命令将从您使用 Dockerfile 和你的构建命令，然后一旦你的 script.sh 完成执行，它就会完成。
I am new to docker. I have a shell script that loads data into impala and I want a docker file that runs builds an image and run the container.
I am on mac, installed boot2docker and have the DOCKER_HOST env set up.
bash-3.2$ docker info

I am trying to just installed a pre-built image using:
sudo docker pull busybox
I get this error:
sudo docker pull busybox
2014/08/18 17:56:19 Post http:///var/run/docker.sock/images/create?fromImage=busybox&tag=: dial unix /var/run/docker.sock: no such file or directory
Is something wrong with my docker setup?
When I do a docker pull busybox, It pulls the image and download is complete.
bash-3.2$ docker pull busybox

Hello Doctor
Am I missing something?
You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.
You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.
You can confirm this by doing a:
$ env
Then a
$ sudo env
And looking for DOCKER_HOST in each output.
As for having a docker file that runs your script, something like this might work for you:
Dockerfile
FROM busybox
# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh
# Run your script
CMD /usr/local/bin/script.sh
Then you can run:
docker build -t your-image-name:your-tag .
This will build your docker image, which you can see by doing a:
docker images
Then, to run your container, you can do a:
docker run your-image-name:your-tag
This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.
