Question

我重新安装了Docker。当我试图启动Docker时，一切都很好：

# /etc/init.d/docker start
[ ok ] Starting docker (via systemctl): docker.service.

直到我想停止Docker服务并多次重启它：

# /etc/init.d/docker stop

[....] Stopping docker (via systemctl): docker.serviceWarning: Stopping docker.service, but it can still be activated by:
  docker.socket
. ok

最后，我有错误：

# /etc/init.d/docker start
[....] Starting docker (via systemctl): docker.serviceJob for docker.service failed.
See "systemctl status docker.service" and "journalctl -xe" for details.
 failed!

# systemctl status docker.service

我在Debian 9 Stretch上安装了Docker。

任何人都可以帮我摆脱这个警告并解决错误“结果失败'start-limit-hit'”？

Answer 1

如果 docker 由套接字触发，只需启动和停止套接字。

sudo systemctl stop docker.socket

Answer 2

这是因为除了docker.service单元文件外，还有一个docker.socket单元文件......这是用于套接字激活的。警告意味着如果您在docker服务未运行时尝试连接到docker socket，则systemd将自动为您启动docker。您可以删除/lib/systemd/system/docker.socket来解决此问题...您可能还需要从-H fd://单元文件中删除docker.service。

警告：停止docker.service，但它仍然可以通过以下方式激活：docker.socket
