没有 Docker 桌面的 WSL2 Alpine 中的 Docker

Question

没有 Docker Desktop 的 WSL1 下的 Docker 是不可能的，所以我试图按照这篇文章从WSL2 Alpine 中运行 Docker。

但是，我没有那么幸运能够让它工作。 完整的日志包括在下面。

请问有谁知道哪里出错了？

整个过程在alpine/v3.15下完成（从https://apps.microsoft.com/store/detail/alpine-wsl/9P804CRF0395?hl=en-us&gl=US安装）——

Answer 1

您可以按照链接到的博客文章中的说明运行 Docker 守护程序：

sudo dockerd

然后切换到另一个 WSL Alpine 实例并运行 Docker 客户端命令。

但要使用 OpenRC Docker 服务，您有两种选择。

首先，您可以启动 OpenRC，然后手动启动 Docker 服务：

openrc default
rc-service docker start # or service docker start

或者您可以将 Docker 服务添加到默认运行级别（一次性），然后只要在该运行级别启动 OpenRC，它就会运行：

一度：

rc-update add docker default

然后，使用默认运行级别启动 OpenRC，这也将运行 Docker：

openrc default

真的，您似乎唯一缺少的是 OpenRC 没有首先初始化。 通常，这将在 Alpine 初始化期间完成，但 WSL 自己的/init正在运行。
