Azure App Service容器6000端口无HTTP响应，WEBSITES_PORT配置无效求助

将Docker镜像构建并部署至Azure容器注册表（ACR）与App Service，已在Dockerfile中暴露6000端口，并在应用设置中配置WEBSITES_PORT，但持续收到“容器未响应HTTP ping”错误。应用日志显示已在容器内的127.0.0.1:6000运行，但怀疑端口未发布到主机，且无法修改docker run命令，同时对部分环境变量来源存在疑问，寻求解决办法。

已尝试的解决方案 #

• 仅设置PORT=6000
• 仅设置WEBSITES_PORT=6000
• 同时设置PORT=6000与WEBSITES_PORT=6000
• 升级App Service计划
• 尝试SSH连接App Service，显示“SSH CONN CLOSE”

疑问 #

1. 我的理解是否有误？应用已在容器内运行（日志显示Running on http://127.0.0.1:6000），但端口未发布到主机，docker run命令仅含--expose参数无-p参数，导致无法响应HTTP ping？
2. 由于无法修改docker run命令，该如何解决问题？
3. NODE_OPTIONS、StartupBootstrapper、DOTNET_SHARED_STORE这类环境变量的来源是什么？
