Question

因此，目标是建立一个由4个raspis，1个master和3个worker组成的kubernetes集群。我正在遵循this指南。初始设置后，群集工作正常，但在重新启动后变得无用。经过一番调查后，我发现docker守护进程在重新启动后无法重新启动存在问题，这导致必需的kubernetes容器无法启动。重新启动后，我的文件系统也进入只读模式。 sudo service docker status的输出显示以下内容

docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 2019-10-03 12:23:57 CEST; 21min ago

尝试运行任何docker命令会导致

ERROR: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

，并通过curl -sSL get.docker.com | sh && sudo usermod pi -aG docker && newgrp docker安装了docker。

我什至无法卸载它，因为它不是通过apt-get安装的：

sudo apt-get remove docker
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package 'docker' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 62 not upgraded.

journalctl -xe ist

的输出

我用Google搜索了遇到的各种错误，但是它们只导致github错误，该错误已经2岁了，并且没有解决或通过无济于事的解决方案解决了。（参考this，this和this）

我也尝试过sudo systemctl enable docker来自动启动，但是我认为这不是问题所在。它看起来像是可以通过全新安装解决的配置问题，如果我要运行应该能够正常关闭的kubernetes集群，则需要避免此问题。我真的希望有人能帮助我。
