Question

我已经关注了installation instructions of Docker CE for CentOS。最初这很有效。在某些时候系统重新启动，现在启动Docker失败。欣赏专家对此事的看法......

systemctl start docker产生：

docker.service的作业失败，因为控制进程退出并显示错误代码。请参阅＆＃34; systemctl status docker.service＆＃34;和＆＃34; journalctl -xe＆＃34;详情。

systemctl status docker.service产生：

Answer 1

从这里开始：https://github.com/moby/moby/issues/22507

我跑了：

ps axf | grep docker | grep -v grep | awk '{print "kill -9 " $1}' | sudo sh

然后我可以使用：

重启docker

sudo systemctl start docker

Answer 2

从poruction机复制卷时，我得到了此消息，最终在metadata.db内对/var/lib/docker/volumes进行了强行压缩，然后崩溃了。修复是如此之简单

docker system prune --volumes -f && rm /var/lib/docker/volumes/metadata.db && docker-compose up -d

由于＆＃34;卷存储元数据库，Docker无法启动：超时＆＃34;
