goreplay 是一個很不錯的流量拷貝，復制工具，小巧，支持一些擴展，當然也提供了企業版，企業版
功能更強大，支持二進制協議的分析 。
為了方便數據的存儲，我們可以使用es 進行存儲

使用了一個tini 的工具，方便后台任務運行,同時因為wget 二進制包太慢，所以直接下載add 了
FROM openresty/openresty:alpine-fat
LABEL author="1141591465@qq.com"
COPY gor_0.16.1_x64.tar.gz .
RUN apk add --update && apk add --no-cache tini \
&& tar xzf gor_0.16.1_x64.tar.gz -C /usr/local/bin \
&& rm gor_0.16.1_x64.tar.gz
ENV PATH=$PATH:/usr/local/bin
ADD entrypoint.sh /entrypoint.sh
ADD goreplay.sh /goreplay.sh
ENTRYPOINT ["/sbin/tini","-s", "--", "/entrypoint.sh"]
- entryppint.sh
#!/bin/sh
sh goreplay.sh
exec /usr/local/openresty/bin/openresty -g "daemon off;"
- goreplay.sh
goreplay 的運行命令，主要是進行流量的拷貝
#!/bin/sh
#!/bin/sh
nohup goreplay --input-raw :80 --output-http "http://app" --output-http "http://app2" --output-http-elasticsearch es:9200/gor &
