我想让容器在计算机重启后自动启动，所以我使用了“--restart=always”标志，但它没有按预期运行。当我重新启动系统时，容器没有启动。
我曾尝试将存储驱动程序从 aufs 更改为 overlay2，使用“-s overlay2”，但我没有帮助。

i user '$ docker logs db-mysql' 显示容器上次登录时间，重启后不会改变。所以我觉得不是容器重启后启动，稍后退出的情况
最佳答案
我的问题解决了。这是由于在docker 启动过程中缺少/etc/resolv.conf 造成的。
docker daemon 尝试启动容器，但找不到文件/etc/resolv.conf，因此失败。
/etc/reslv.conf 是/var/run/NetworkManger/resolv.conf 的链接文件。
在我的操作系统中，/etc/resolv.conf 将由 NetworkManager 更新，因为它不是静态 ip，所以，在我登录并连接到网络之前，这个文件不存在!
我在/etc/NetworkManager/NetworkManager.conf 中更改NetworkManger 的配置，在[main] 区域中设置'dns=none'，因此它停止修改resolv.conf。 同时删除链接文件/etc/resolv.conf，为/etc/resolv.conf添加一个新文件，如'nameserver=8.8.8.8'
重新启动后，docker 容器可以自动启动，工作正常!
关于linux - 重新启动后 docker 无法启动容器使用 '--restart-always'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42088043/
