Docker [for mac]文件系统变为只读，这破坏了Docker的几乎所有功能 [英] Docker [for mac] file system became read-only which breaks almost all features of docker

问题描述

我的Docker进入错误状态，无法再使用它.

My Docker ran into an error state, where I cannot use it anymore.

docker system info的输出:

在我构建了以下Dockerfile之后，发生了此行为:

This behaviour occured, after I built the following Dockerfile:

FROM perl:5.20

FROM perl:5.20

运行apt-get更新&& apt-get install -y libsoap-lite-perl \
&& rm -rf/var/lib/apt/lists/*

RUN apt-get update && apt-get install -y libsoap-lite-perl \
&& rm -rf /var/lib/apt/lists/*

运行cpan SOAP :: LITE

RUN cpan SOAP::LITE

当我尝试构建映像或运行容器或删除映像时，错误消息总是与此类似:

the error message when I try to build an image or run a container or remove an image is always similar to this:

Error: open /var/lib/docker/swarm/worker/tasks.db: read-only file system

例如，如果我尝试执行此命令:

for example if I try to execute this command:

docker container run -it perl:5.20 bash

我收到此错误:

docker: Error response from daemon: mkdir /var/lib/docker/overlay2/1b966e163e500a8c78a64e8d0f14984b091c1c5fe188a60b8bd030672d3138d9-init: read-only file system.

我该如何重置我的码头工人，以使这些错误消失?

How can I reset my docker so these errors go away?

推荐答案

转到右上角的docker for mac Icon，单击它，然后单击重新启动". 之后，Docker将按预期工作.

Go to your docker for mac Icon in the top right, click on it and then click Restart. After that Docker works as expected.

这似乎是一个临时性的问题，因为在重启docker之后我无法重现它.我的猜测是，当Docker尝试在Dockerfile中下载并安装软件包时，我发生了网络通信故障.

This seems to be an temporary issue since I cannot reproduce it after restarting docker. My guess is that I had an network communication breakdown while docker tried to download and install the packages in the Dockerfile.
