在Ubuntu 16.04上无法连接到unix:/var/run/docker.sock上的Docker守护程序
在Ubuntu 16.04上无法连接到unix:/var/run/docker.sock上的Docker守护程序

意外的是，我的docker出了问题，无法启动。
docker ps给出以下错误
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?而systemctl status docker.service给出了以下输出：
● docker.service - Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

skyuua提到的同一线程中的more recent answer建议如下(它将-H fd://更改为-H unix://)
sudo systemctl编辑docker.service
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H unix:// -H tcp://127.0.0.1:2375紧接着是
sudo systemctl守护进程-重新加载
sudo systemctl重启docker.service
在我的Ubuntu16.04和docker 18.0.3上，这重写了/etc/systemd/system/docker.service.d/override.conf文件，允许docker正确启动。

我们运行sudo apt-get update，我们的docker版本也更新了，从18.09.1更改为18.09.3，docker变得混乱。经过网上挖掘，我找到了下面的解决方案，为我们解决了问题。
sudo systemctl edit docker.service
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd-ce -H unix://var/run/docker.sock -H tcp://0.0.0.0:2375然后重启服务
sudo systemctl restart docker.service页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
