docker flannel子网问题

码头工人没有捡到法兰绒。任何帮助都将是巨大的。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。 法兰绒正在按预期工作

检查

/run/flannel/flannel\u docker\u opts.env

是否存在及其内容。 我的

/run/flannel/subnet.env

看起来像：

法兰绒_网络=10.252.0.0/16

法兰绒_子网=10.252.127.1/24

法兰绒_MTU=1450

法兰绒_IPMASQ=假

将

--bip=${FLANNEL\u SUBNET}--mtu=${FLANNEL\u mtu}

添加到dockerd参数

如果这无法工作，

rm-rf/var/lib/docker/overlay2/*

并重新启动docker.service
