本地配置hosts

127.0.0.1 xxxx.xxx.com

启动docker

$ docker run -d -p 10000:10000 -v `pwd`/envoy.yaml:/etc/envoy/envoy.yaml --name envoyproxy envoyproxy/envoy-alpine:v1.14.1

测试

curl --location --request GET 'http://xxx.xxxx.com:10000/im/account/get?accountId=liuk'

说明

当请求xxx.xxxx.com时，实际到本地的127.0.0.1:10000,即请求到envoy，envoy会将请求转发至62.234.197.82:80
