无法连接到容器：拨号失败 [英] Failed to connect to containerd: failed to dial

问题描述

只需按照官方说明在Ubuntu 14.04中的存储库中安装Docker CE

Just installed Docker CE following official instructions with the repository in Ubuntu 14.04

安装成功，守护进程正在运行

Installation went successfully, the daemon is running

$ ps aux | grep docker
[...] /usr/bin/dockerd --raw-logs [...]

我的用户在docker组中：

My user is in the docker group:

$ groups
[...] docker

cli似乎无法通信（与sudo相同）

The cli can't seem to communicate (same with sudo)

$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock.
Is the docker daemon running?

套接字似乎具有正确的权限：

The socket seems to have the correct permissions:

$ ls -l /var/run/docker.sock
srw-rw---- 1 root docker 0 Feb  4 16:21 /var/run/docker.sock

日志似乎声称存在某些问题

The log seems to claim about some issues though

$ sudo tail -f /var/log/upstart/docker.log

有任何建议可以使这项工作吗？

Any advice to make this work ?

记录和Docker重新启动当然已经完成

推荐答案

同样的情况发生在我身上。是因为您的Linux内核版本太低！使用命令 uname -r检查它，如果版本低于 3.10（例如：debian 7 whezzy默认版本为3.2），即使您成功安装了docker-ce，您仍将无法启动docker daemon成功。这就是为什么！网络上的所有大多数答案都告诉您重新开始 bla bla bla ...，但他们并未考虑此问题。

Same situation happend on me. IS because your linux kernel version too low !!! check it use command "uname -r" , if the version below "3.10" (for example: debian 7 whezzy default version is 3.2 ) ,even you install docker-ce suceessfully, you will still can not start docker daemon success.That why! All most answers on the web tell you to 'restart' bla bla bla... but they did not consider this problem.
