Windows10中未安装Docker Desktop，而是通过WSL2安装linux内核docker。在使用VSCode Remote运行远程容器时出现问题，无法正常使用。记录解决方案如下：

前提条件

WSL2 安装 Docker Without Docker desktop

设置 WSL 开发环境

Windows 不安装Docker Desktop使用Docker命令

下载单独的windows docker文件

windows

解压并设置环境变量

将解压路径设置至环境变量path中
docker -v 验证成功
docker ps 失败
接下来继续解决

WSL2 公开 Docker 守护程序并为其创建上下文

在 WSL2 中，更改服务配置以在本地主机上额外公开 Docker 守护程序：

sudo cp /lib/systemd/system/docker.service /etc/systemd/system/
sudo sed -i 's/\ -H\ fd:\/\//\ -H\ fd:\/\/\ -H\ tcp:\/\/127.0.0.1:2375/g' /etc/systemd/system/docker.service
sudo systemctl daemon-reload
sudo systemctl restart docker.service

Windows 设置DOCKER_HOST

增加环境变量：
DOCKER_HOST = tcp://localhost:2375

验证：
docker ps
docker images
docker run hello-world
均可成功

Configure VSCode to access to WSL2 docker

To do so, click on the icon (?) on the top right of the section “Containers” and select “Edit settings…”

You’ll get around 56 settings and you search for “Docker:Host” where you put the line “tcp://localhost:2375” where you can replace the highlighted ip address by the one you got before

Once done, you come back to the panel and you click on “refresh” icon (top right of each sections) and you would get information from your dockerd running in WSL2
