how to deploy v2ray client on k8s

1. create a configmap

   kubectl create configmap v2ray --from-file=/etc/v2ray/config.json
   

2. create a pod

   an example yaml file:

   apiVersion: v1
   kind: Pod
   metadata:
     name: v2ray
   spec:
     nodeName: node
     containers:
       - name: v2ray
         image: v2ray/official
         volumeMounts:
         - name: v2ray
           mountPath: /etc/v2ray/config.json
           subPath: config.json
         imagePullPolicy: IfNotPresent
         command: [ "/bin/sh" ]
         args: ["-c","v2ray -config=/etc/v2ray/config.json"]
     volumes:
     - name: v2ray
       configMap:
         name: v2ray
   

   kubectl create -f pod.yaml
   

3. create a pod label

   kubectl get pod --show-labels
   kubectl label pod v2ray app=v2ray
   

4. create a service

   an example yaml file:

   apiVersion: v1
   kind: Service
   metadata:
     name: v2ray
   spec:
     selector:
       app: v2ray
     type: NodePort
     ports:
       - protocol: TCP
         port: 1080
         targetPort: 1080
         nodePort: 30000
   

   kubectl create -f service.yaml
   

at last, you can use tcpdump port 10080 to monitor network traffic comes from k8s master(if used) and node on v2ray server.
