MEF Edge Log Refreshing

Symptom

After MEF Edge is successfully interconnected with CloudCore, edge_main generates a large number of messages. As a result, logs are refreshed.

edgecore proxy receive msg router: {Source: Destination:EdgeCore Option:query Resource:default/node/***}, route: {Source:edge_main Group:resource Operation:response Resource:default/node/***}

Cause Analysis

kube-controller-manager does not allocate CIDR to nodes, and EdgeCore continuously queries the node status until CIDR is allocated.

Solution

1. Log in to the host where MEF Center is installed.
2. Modify the kube-controller-manager configuration file and configure the startup parameters cluster-cidr and allocate-node-cidrs of kube-controller-manager.

   The kube-controller-manager configuration file is usually named /etc/kubernetes/manifests/kube-controller-manager.yaml.

   Example:

   --cluster-cidr=192.168.0.0/16 
   --allocate-node-cidrs=true
