警告：停止docker.service，但它仍然可以通過啓動：docker.socket

Question

我已經重新安裝了Docker。當我試圖啓動泊塢窗，一切都很好：

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

，直到我想停下來泊塢窗的服務和多次重新啓動：

# /etc/init.d/docker stop 

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

最後，我有錯誤：

# /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!

我在Debian 9 Stretch上安裝了Docker。

任何人都可以幫助我擺脫這個警告並解決一個錯誤「失敗，結果'開始限制命中'」？

這是因爲除了docker.service單元文件，還有一個docker.socket單元文件...這是用於套接字激活。警告意味着，如果您在docker服務未運行時嘗試連接到docker套接字，systemd將自動爲您啓動docker。 您可以通過刪除/lib/systemd/system/docker.socket來擺脫此問題...您可能還需要從docker.service單元文件中刪除-H fd://。
