envoy 测试试用

备注：为了简单测试使用的是docker 镜像进行的测试

1. Dockerfile

FROM lyft/envoy:latest
RUN apt-get update
COPY envoy.json /etc/envoy.json
CMD /usr/local/bin/envoy -c /etc/envoy.json

2. envoy.json

    }
}

 
 
   简单说明： 请求ip:10000  的地址重定向到baidu  管理界面为ip:9901

3. 测试效果（只演示管理界面）

4. 总结

功能还是比较强大的，结合容器进行开发，可以充分发挥云原生应用的价

充分发挥云原生应用的价值
