为了方便测试dataplaneapi 基于官方的docker镜像,制作了一个简单的包含dataplaneapi 的镜像

下载dataplaneapi

https://github.com/haproxytech/dataplaneapi/releases

Dockerfile

FROM haproxy:2.0.5
COPY dataplaneapi /usr/local/sbin/dataplaneapi
RUN chmod +x /usr/local/sbin/dataplaneapi

简单参考配置文件

通过processmanager 管理

# This is the ultimate HAProxy 2.0 "Getting Started" config
# It demonstrates many of the features available which are now available 
# While you may not need all of these things, this can serve
# as a reference for your own configurations.
