无法创建docker网络：在分配给网络的默认值中找不到可用的，不重叠的IPv4地址池

问题描述 投票：2回答：1

命令docker create network mynetwork给了我以下错误响应：

Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

我已经搜索了此错误，但是这些解决方案均无效：

  1. 我只有3个预定义的docker网络，所以docker network prune没有区别。
  2. 我从未安装过OpenVPN

the defaults部分是指码头工人正在使用的31 predetermined address ranges，除非您在运行命令时指定了--subnet选项（在这种情况下错误将消失）：

$ docker network create abcd --subnet 172.17.0.0/16 

Docker守护程序的日志输出表明，它实际上正在尝试分配这31个默认子网中的几乎每个子网。分配失败的可能原因只有两个。
名称服务器重叠
如果您的DNS服务器属于该子网，则Docker将不使用默认子网。显然，这不太可能成为问题，但是我们仍然可以通过配置一些（虚拟）名称服务器来重现您的错误，每个31个默认子网中的每个名称服务器：
$ cat /etc/resolv.conf
nameserver 172.17.0.1
nameserver 172.18.0.1
nameserver 172.19.0.1
nameserver 172.20.0.1
nameserver 172.21.0.1
nameserver 172.22.0.1
nameserver 172.23.0.1
nameserver 172.24.0.1
nameserver 172.25.0.1
nameserver 172.26.0.1
nameserver 172.27.0.1
nameserver 172.28.0.1
nameserver 172.29.0.1
nameserver 172.30.0.1
nameserver 172.31.0.1
nameserver 192.168.0.1
nameserver 192.168.16.1
nameserver 192.168.32.1
nameserver 192.168.48.1
nameserver 192.168.64.1
nameserver 192.168.80.1
nameserver 192.168.96.1
nameserver 192.168.112.1
nameserver 192.168.128.1
nameserver 192.168.144.1
nameserver 192.168.160.1
nameserver 192.168.176.1
nameserver 192.168.192.1
nameserver 192.168.208.1
nameserver 192.168.224.1
nameserver 192.168.240.1

$ docker network create abcd
Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

阅读此内容的Ubuntu用户可以使用/run/systemd/resolve/resolv.conf执行相同的操作。
IP路由重叠
Docker官方文档指向article，上面写着
  
默认情况下，网桥从范围172. [17-31] .0.0 / 16或192.168。[0-256] .0 / 20分配了一个子网，该子网不与任何现有主机接口重叠。
这意味着，就像使用名称服务器一样，我们可以通过向我们的路由表中添加与所有31个默认子网匹配的（虚拟）路由来重现您的错误：
$ ip route add 172.16.0.0/12  dev lo
$ ip route add 192.168.0.0/16 dev lo

$ docker network create abcd
Error response from daemon: could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

解决IP路由重叠
在您的情况下，很可能需要考虑两个目的来分析ip route的输出：
    查找和删除与172.[17-31].0.0/16或192.168.[0-256].0/20冲突的不必要的路由
  1. 或查找未使用的IP范围以与--subnet选项一起使用。如果主机连接到Internet，则该范围应位于10.0.0.0/8的专用网络172.16.0.0/12，192.168.0.0/16或RFC-1918内。
  2. 其余与OP无关，但可能对来自搜索的用户有所帮助
OpenVPN
已设置选项--redirect-gateway def1（或从VPN服务器推送），OpenVPN会将IP路由0.0.0.0/1和128.0.0.0/1添加到路由表中。并且由于这两个子网与任何可能的子网重叠，因此将导致所讨论的错误。
可以改为使用--redirect-gateway（不带标志）选项来避免，（如果从VPN服务器推送了原始选项，则与--pull-filter ignore "redirect-gateway def1"组合使用。
Docker撰写
这里（大致上）相当于--subnet 172.17.0.0/16中的docker-compose.yml选项：
networks:
  default:
    ipam:
      config:
      - subnet: 172.17.0.0/16
