我的 Docker 进入了错误状态，我无法再使用它。

最佳答案

转到右上角的 docker for mac 图标，单击它，然后单击重新启动。
之后 Docker 按预期工作。

这似乎是一个临时问题，因为在重新启动 docker 后我无法重现它。我的猜测是，当 docker 尝试下载并安装 Dockerfile 中的软件包时，我遇到了网络通信故障。

关于perl - Docker [for mac] 文件系统变为只读，这几乎破坏了 docker 的所有功能，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52871619/
