UE4.27 linux云服务器像素流部署（2）

一、UE4.27 linux 像素流示例项目

     按照官方像素流示例演示 https://github.com/EpicGames/UnrealEngine/tree/release/Engine/Extras/Containers/Examples/PixelStreaming

        访问UE github 源码容器内容更新较慢，缺少一些配置文件 ，通过开发容器可以复制出最新的文件

docker ps

      docker-compose.yml  信令服务器更改成阿里云分享的镜像

        /project/Dockfile    开发镜像和运行时镜像更改成阿里云分享的镜像

      执行./sh，显示像素流启动正常

      Google Chrome 访问公网ip+端口测试网页访问是否正常
