启用 Docker TCP 连接

2023-02-152023-02-17Notes

原始问题，一言以蔽之就是在 daemon.json 增加 Host 之后，服务会启动失败。

解决方案:

  • 在 /etc/systemd/system/docker.service.d/simple_dockerd.conf 中增加 
    [Service]
    ExecStart=
    ExecStart=/usr/bin/dockerd
  • 在 /etc/docker/daemon.json 中增加 
    {"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}
  • 重启 docker 服务 
    systemctl daemon-reload && 
    systemctl restart docker.service
  • 检查 docker 服务状态 
    ❯ systemctl status docker.service
    ● docker.service - Docker Application Container Engine
        Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
        Drop-In: /etc/systemd/system/docker.service.d
                └─simple_dockerd.conf
        Active: active (running) since Wed 2023-02-15 11:49:01 CST; 1h 18min ago
    TriggeredBy: ● docker.socket
