在AWS ECS Fargate部署FastAPI+PostgreSQL遇容器无日志退出问题

我尝试通过Docker Compose在AWS ECS Fargate上部署FastAPI + PostgreSQL应用时，容器启动后立即停止，退出码为0（无错误），且CloudWatch未生成任何日志。

本地环境中，Docker化的FastAPI和PostgreSQL运行正常，但加载HuggingFace的ColPali模型需约8分钟才能启动API端点。我已配置ecsTaskExecutionRole策略、s3:GetObject权限及ECR访问权限，此前曾成功部署无额外依赖的简单FastAPI应用。

操作步骤：

• 使用AWS CLI创建仓库、构建、标记并推送Docker镜像；
• 创建默认配置的集群；
• 创建任务定义，任务角色为ecsTaskExecutionRole，采用Linux/ARM64架构（Mac M2芯片），通过S3加载环境变量；
• 在集群中以默认配置运行新任务。

目前已无调试思路，寻求帮助。
