Flannel Configuration Kubernetes Network Interoperability Experiment

Configuring the Flannel serviceRepeat the k8s installation section Flanneld related content Step 1:grafana smtp configuration kubernetes

Nohup./flanneld--listen=0.0.0.0:8888 >>/opt/kubernetes/logs/flanneld.log 2>&1 & 110 Start server process on host kubernetes pod configuration file

Nohup./flanneld-etcd-endpoints=http://192.168.161.110:2379-remote=192.168.161.110:8888 >>flanenl.log 2> &1 & #各minons结点上启动flanneld

/** set up subnets on the ETCD server * * configure docker registry in kubernetes
Etcdctl set/coreos.com/network/config ' {"Network": "10.1.0.0/16"} '

Step 2:

Performing subnet segment settings on the ETCD server kubernetes application configuration

Etcdctl set/coreos.com/network/config ' {"Network": "10.1.0.0/16"} 'pod configuration kubernetes

Step 3:

Restart Docker Kubelet Kube-proxy
