1. 检查 docker.service
sudo systemctl status docker
输出结果大致如下:
● docker.service - Docker Application Container Engine

如果出现错误,请重新启动它:
sudo systemctl restart docker
然后再次检查status
。如果没有解决问题,接下来执行以下步骤:
2. 请求与守护程序套接字的连接,查看其是否已启动:
curl --unix-socket /var/run/docker.sock http://localhost/_ping; echo
输出只是一个OK
消息。
OK
如果收到的不是 OK
,而是类似于以下内容:
curl: (7) Couldn't connect to server
3. 检查套接字服务
sudo systemctl status docker.socket
一个良好的输出将是:
● docker.socket - Docker Socket for the API
Loaded: loaded (/lib/systemd/system/docker.socket; enabled; vendor preset: enabled)
Active: active (running) since Sat 2021-12-04 19:10:57 +0330; 6min ago
Listen: /var/run/docker.sock (Stream)
Tasks: 0 (limit: 4915)

Dec 04 19:10:57 elitedesk systemd[1]: Starting Docker Socket for the API.
Dec 04 19:10:57 elitedesk systemd[1]: Listening on Docker Socket for the API.
即使看起来良好,也要重新启动它。因为在停止守护程序并再次启动后,它不起作用,我们应该(据我所知)重新启动docker.socket
。
sudo systemctl restart docker.socket
你之前没有能够修复它吗?接下来:
4. 直接以调试
模式运行后台进程
sudo dockerd -D -l debug
18.06.0-ce
