Docker 无法连接到 docker 守护进程 [英] Docker can't connect to docker daemon

问题描述

在我将 Docker 版本更新为 0.8.0 后，我在输入 sudo docker version 时收到一条错误消息:

After I update my Docker version to 0.8.0, I get an error message while entering sudo docker version:

Client version: 0.8.0
Go version (client): go1.2
Git commit (client): cc3a8c8
2014/02/19 12:54:16 Can't connect to docker daemon. Is 'docker -d' running on this host?

我已经按照说明输入了命令 sudo docker -d，然后我得到了这个:

And I've followed the instructions and entered command sudo docker -d, and I got this:

[/var/lib/docker|2462000b] +job initserver()

我该如何解决问题?

推荐答案

Linux

Linux 的安装后步骤 文档揭示了以下步骤:

Linux

The Post-installation steps for Linux documentation reveals the following steps:

1. 创建docker 组.

sudo groupadd docker

将用户添加到 docker 组.

sudo usermod -aG docker $(whoami)

注销并重新登录以确保 docker 以正确的权限运行.

启动docker.

Log out and log back in to ensure docker runs with correct permissions.

Start docker.

sudo service docker start

Mac OS X

正如 Dayel Ostraco 所说，添加环境变量是必要的:

Mac OS X

As Dayel Ostraco says is necessary to add environments variables:

docker-machine start # Start virtual machine for docker
docker-machine env  # It's helps to get environment variables
eval "$(docker-machine env default)" # Set environment variables

docker-machine start 命令输出注释以指导过程.

The docker-machine start command outputs the comments to guide the process.
