eproxy

eProxy is a lightweight and efficient replacement for kube-proxy in Kubernetes environments, leveraging eBPF (Extended Berkeley Packet Filter) technology for enhanced performance and flexibility.

How to deploy

git clone https://github.com/K-Huntun/eproxy.git
cd eproxy/deploy
kubectl apply -f deploy.yaml

How to use

kubectl create ns nginx kubectl apply -f svc.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
    service.kubernetes.io/service-proxy-name: eproxy
  name: nginx-bpf
  namespace: nginx
spec:
  ports:
  - port: 80
    protocol: TCP
    targetPort: 80
  selector:
    app: nginx
  type: ClusterIP
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nginx
  name: nginx-deploy
  namespace: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx
        ports:
        - containerPort: 80
        name: nginx

kubectl exec -it <other-pod> bash
curl nginx-bpf:8080

卸载

Due to the fact that eproxy mounts the BTF file internally within the container, when eproxy is unmounted or when the container is killed for other reasons, both the eBPF program and map data of eproxy will disappear. Upon container restart, they will be reloaded again.

kubectl delete -f deploy.yaml

How to build

docker build -it --rm -v ${eproxy_home}:/root/eproxy registry.cn-hangzhou.aliyuncs.com/secrity/eproxy_build:0.0.1 bash
cd /root/eproxy
make clean all
