由于错误无法在 Ubuntu WSL 上运行 Docker 无法连接到 unix:///var/run/docker.sock 上的 Docker 守护进程.docker 守护进程是否正在运行?

问题描述

我在 Windows 10 机器上运行 WSL 2 (Ubuntu).我使用官方 Docker 指南 (

...从默认 WSL2 访问

基于这篇文章.Linux 开发人员使用 WSL 2、Docker 桌面的 Windows 环境和 docker 文档.Docker 桌面 WSL 2 后端

以下仅适用于 WSL1

docker 似乎无法在 WSL 中运行.他们建议将 WSL 连接到在 Windows 中运行的 docker 桌面:为 Windows 和 WSL 设置 Docker

在 docker 论坛中，他们也提到了该解决方案:无法连接到 docker 守护进程

希望有所帮助.

I am running WSL 2 (Ubuntu) on a Windows 10 machine. I installed Docker on my Ubuntu using the official Docker guide (https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository). Running docker run hello-world produces the following error: docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

I have tried the following steps:

1. Using sudo docker... instead of docker...
2. Adding user to docker usergroup with sudo usermod -aG docker $(whoami)
3. sudo nohup docker daemon -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock & which I found in this thread: https://forums.docker.com/t/cannot-connect-to-the-docker-daemon-is-the-docker-daemon-running-on-this-host/8925/4

None of these steps helped.

docker version produces this output:

Client: Docker Engine - Community

 API version:       1.40
 Go version:        go1.12.17

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

service docker status gives Docker is not running. service docker start/restart does nothing, Docker does not start. Any ideas what could be the issue?

解决方案

I found your question, as I was trying to achieve the same. {I have updated my question as with the latest windows update, the process it's much more easier}

Using WSL2

You simply have to activate and use WSL2, I have to install Ubuntu 20.04 as the 18.04 wasn't connecting with Docker desktop. In the windows shell:

To check the WSL mode, run

wsl -l -v

To upgrade your existing Linux distro to v2, run:

wsl --set-version (distro name) 2

WSL Integration will be enabled on your default WSL distribution. To change your default WSL distro, run

wsl --set-default <distro name>

Then in docker you have to.

...use the WSL2 engine

...access from your default WSL2

Based on this article.A Linux Dev Environment on Windows with WSL 2, Docker DesktopAnd the docker docs.Docker Desktop WSL 2 backend

Below is valid only for WSL1

It seems that docker cannot run inside WSL. What they propose is to connect the WSL to your docker desktop running in windows: Setting Up Docker for Windows and WSL

In the docker forums they also refer to that solution: Cannot connect to the docker daemon

Hope that helps.
