Docker没有拿起法兰绒子网。任何帮助都会很棒。我是使用coreos作为我的容器Linux和docker版本是1.12.6 我的docker启动文件如下所示。法兰绒按预期工作

检查/run/flannel/flannel_docker_opts.env是否存在及其内容。我的/run/flannel/subnet.env看起来像是：

FLANNEL_NETWORK = 10.252.0.0 / 16

FLANNEL_SUBNET = 10.252.127.1 / 24

FLANNEL_MTU = 1450

FLANNEL_IPMASQ =假
将--bip=${FLANNEL_SUBNET} --mtu=${FLANNEL_MTU}添加到dockerd args。
如果这不起作用，rm -rf /var/lib/docker/overlay2/*并重新启动docker.service
