networking - Docker守护程序无法初始化网络 Controller

Question

我在启动Docker守护程序时遇到问题。我已经安装了docker，但是当我尝试运行# systemctl start docker.service时会抛出错误。$ systemctl status docker.service给了我这个:

● docker.service - Docker Application Container Engine

Answer 1

您的错误文字被剪切，因此我无法检查它是否完全相同，但我收到此错误:

Error starting daemon: Error initializing network controller: Error creating default "bridge" network: failed to parse pool request for address space "LocalDefault" pool "" subpool "": could not find an available predefined network

这与具有多个网卡的计算机有关(也可能在具有VPN的计算机中发生，您也可以暂时将其停止，启动docker并重新启动vpn或应用以下解决方法)
对我来说，解决方案是像这样手动启动docker:

/usr/bin/docker daemon --debug --bip=192.168.y.x/24

其中192.168.y.x是主计算机IP，而/ 24是ip网络掩码。 Docker将使用此网络范围来构建网桥和防火墙规则。 --debug并不是真正需要的，但是如果其他原因失败了，可能会有所帮助
启动一次后，您可以杀死docker并照常启动。 AFAIK， docker 已经为该--bip创建了一个缓存配置，并且无需它就可以正常工作。当然，如果您清理Docker缓存，则可能需要再次执行此操作。
