aasmith/haproxy Docker 镜像 - 轩辕镜像 | Docker 镜像高效稳定拉取服务

aasmith/docker-haproxy

镜像概述和主要用途

该Docker镜像包含HAProxy，且针对更新、更快的库（带JIT的PCRE、SLZ、OpenSSL）进行编译。尽可能使用静态链接的现代库，同时尽量贴近官方Docker镜像。可在需要时替换镜像名称使用。

核心功能和特性

Lua支持

自HAProxy 1.6起，Lua支持可用，无需重新编译或C语言知识即可添加额外功能。

PCRE

启用PCRE JIT编译以加快正则表达式解析速度。PCRE性能项目提供了更多基准测试等信息。编译尽可能接近debian包，但排除C++支持和动态链接。

Stateless Zip (SLZ)

由HAProxy维护者创建的SLZ是一种流压缩器，可生成gzip兼容输出。它内存占用更低，无字典持久性，运行速度约为zlib的3倍。Stateless Zip项目提供背景、基准测试等信息。

Prometheus

从2.0.5版本开始，默认编译Prometheus导出器功能。

可用版本

完整的Docker标签列表可查看GitHub或DockerHub提供的标签。

使用方法

从命令行显示HAProxy版本

docker run -it --rm aasmith/haproxy:2.3.2 haproxy -vv

Dockerfile示例

Dockerfile
FROM aasmith/haproxy
COPY haproxy.cfg /usr/local/etc/haproxy/haproxy.cfg

固定版本使用

FROM aasmith/haproxy:2.3 # 保持在2.3系列的最新版本

FROM aasmith/haproxy:2.3.2 # 精确使用2.3.2版本
