Envoy 測試筆記

---

envoy 提供的官方鏡像：

• envoyproxy/envoy
• envoyproxy/envoy-alpine

鏡像配置文件

/etc/envoy/envoy.yaml

默認監聽 端口：10000

// 測試命令

docker run -d --name envoy-test -p 10000:10000 \
-v /home/zhangfeng/envoy/conf:/etc/envoy/ \
envoyproxy/envoy

docker run -it --name envoy-test -p 10000:10000 envoyproxy/envoy bash

docker rm -f envoy-test

docker restart envoy-test

docker cp envoy-test:/etc/envoy/envoy.yaml /home/zhangfeng/envoy/conf

1、靜態測試
