前言
简介：在搭建视频流直播服务时需要用到ffmpeg、nginx、nginx-rtmp-module，从而实现推流和拉流。但传统的安装方式需要安装各种依赖，受服务器系统的影响，安装繁琐。在此编写Dockerfile用于构建一个docker镜像，实现跨平台一键式安装。
说明:
该镜像在docker镜像仓库中已经有了，地址为 https://hub.docker.com/r/alqutami/rtmp-hls/tags
就可以下载镜像了，自己制作镜像受网络影响可能会制作失败

# 执行执行拉取命令 就可以直接下载镜像了
docker pull alqutami/rtmp-hls

不废话了，直接上Dockerfiel配置
附带docker仓库地址 点我 https://hub.docker.com

Dockerfile编写完毕，现在可以构建镜像了

# 执行构建镜像命令。 . 表示的是Dockerfile文件的位置为当前目录下
docker build -t nginx-rtmp:latest .

镜像制作完毕，可以启动容器玩一玩了
