rancher部署安装好后，无法部署pod
部署一个php7后
一直处于updating状态，如下提示
Deployment does not have minimum availability.
最后报错
ReplicaSet "php7-59d6785ff9" has timed out progressing.; Deployment does not have minimum availability.
点击进入pod，发现一直是
ContainerCreating
docker log kubetel后，发现
network: open /run/flannel/subnet.env: no such file or directory
进入webui，进入kubectl
kubectl get pods
kubectl describe pod [pod name]
k for pod "php7-6dc785bc4c-cvpt2": networkPlugin cni failed to set up pod "php7-6dc785bc4c-cvpt2_default" network: open /run/flannel/subnet.env: no such file or directory
Normal SandboxChanged 41s (x12 over 3m24s) kubelet, k8s-master Pod sandbox changed, it will be killed and re-created.
Warning FailedCreatePodSandBox 29s (x4 over 74s) kubelet, k8s-master (combined from similar events): Failed to create pod sandbox: rpc error: code = Unknown desc = failed to set up sandbox container "5e76636f68ec34c883038146ded8577c4353ca1b12883ac66569b3d212d43665" network for pod "php7-6dc785bc4c-cvpt2": networkPlugin cni failed to set up pod "php7-6dc785bc4c-cvpt2_default" network: open /run/flannel/subnet.env: no such file or directory
提示所缺subnet.env文件
通过docker logs kubetel查看容器日志也可以看到缺少文件
解决办法
查看是否有 /run/flannel/subnet.env，没有则创建
FLANNEL_NETWORK=10.244.0.0/16
FLANNEL_SUBNET=10.244.0.1/24
FLANNEL_MTU=1450
FLANNEL_IPMASQ=true
