Install EdgeMesh

EdgeMesh environment preparation (both cloud/edge)​

This Step may occur Question 6：TLSStreamPrivateKeyFile not exist

Step 1: Remove the taint on the master node.

kubectl taint nodes --all node-role.kubernetes.io/master-

Step 2: Add filter tags to Kubernetes API services.

kubectl label services kubernetes service.edgemesh.kubeedge.io/service-proxy-name=""

Step 3: Enable Kube-API endpoint service of KubeEdge on edges.

On the cloud, enable dynamicController:

vim /etc/kubeedge/config/cloudcore.yaml
# Modify cloudcore.yaml
modules:
  ..
  cloudStream:
    enable: true
    streamPort: 10003
  ..
  dynamicController:
    enable: true
    
# Restart cloucore
systemctl restart cloudcore.service

On the edges, enable metaServer and edgeStream (note that this operation should redo after keadm reset).

vim /etc/kubeedge/config/edgecore.yaml
# Modify edgecore.yaml
edgeStream:  
	enable: true  
	handshakeTimeout: 30  
	readDeadline: 15  
	server: 192.168.0.139:10004  
	tlsTunnelCAFile: /etc/kubeedge/ca/rootCA.crt  
	tlsTunnelCertFile: /etc/kubeedge/certs/server.crt  
	tlsTunnelPrivateKeyFile: /etc/kubeedge/certs/server.key  
	writeDeadline: 15
...
metaManager:
    metaServer:
      enable: true
...

# Restart edgecore
systemctl restart edgecore.service
# Check running state
journalctl -u edgecore.service -f

Step 4: On the edge, test whether the edge Kube-API endpoint functions normally.

# Execute on edges
curl 127.0.0.1:10550/api/v1/services

api

If the return value is an empty list, or it takes a long time (close to 10 seconds) to receive the return value, it indicates that there may be an error in the configuration, please check it carefully.

Deploy edgemesh-agent (cloud)​

Download edgemesh code:

# clone edgemesh code (customized by dayu)
git clone https://github.com/dayu-autostreamer/dayu-edgemesh.git
# move in code directory
cd dayu-edgemesh

Add relay node:

vim build/agent/resources/04-configmap.yaml
# Add the master node (cloud) as relay node for cloud-edge communication：
....
edgeTunnel:
        enable: true
        relayNodes:
        - nodeName: <hostname>
          advertiseAddress:
          - <ip>
....
# Fulfill <hostname> <ip> with hostname and ip of the cloud.

Deploy edgemesh:

# Deploy crd files
kubectl apply -f build/crds/istio/
# Deploy edgemesh-agent
kubectl apply -f build/agent/resources/

NOTE: If using the Intranet Image Repository, please modify the image in the yaml file, such as:

dayuhub/edgemesh-gateway:v1.0 -> repo:5000/dayuhub/edgemesh-gateway:v1.0

Configure edge network (edge)​

Configure the edge:

vim /etc/kubeedge/config/edgecore.yaml
# Modify edgecore.yaml
edged:
    clusterDNS: 169.254.96.16
    clusterDomain: cluster.local

edgecore

edgecore

Restart edgecore:

systemctl restart edgecore

Check running state​

Check iptables state:

iptables -t nat -nvL

iptables

Check the state of edgemesh pods:

kubectl get pods -n kubeedge

normal-run

Logs on the cloud：

kubectl logs -n kubeedge [pod-name]

cloud-agent

Logs on the edge：

# Check edgemesh logs on the edge
kubectl logs -n kubeedge [pod-name]

Uninstall Edgemesh​

If you need to reinstall Edgemesh, please uninstall it first.

cd dayu-edgemesh
kubectl delete -f build/crds/istio/
kubectl delete -f build/agent/resources/
