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？ Windows 10 上的 Linux Bash Shell

Question

我是 Docker 新手。我正在尝试在 Windows 上使用它。
我有 Windows 10 系列，所以我安装了 Linux Bash Shell。
当我运行这个命令时:

$ docker run hello-world

我得到: docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? .
当我运行时

$ systemctl status docker

我明白了

System has not been booted with systemd as init system (PID 1). Can't operate

Answer 1

对于使用 WSL2 并看到相同错误消息的任何人，请查看 https://github.com/MicrosoftDocs/WSL/issues/457#issuecomment-511495846
