Azure 应用服务无法启动 w/ Azure 容器注册表拉取 - Docker 容器 - 找不到文件 - 与 Docker 集线器一起使用

Question

问题：无法从 Azure Container Registry 部署 Flask web 应用程序，即使我可以从 Dockerhub 部署相同的 Docker 图像并让它工作。 日志显示找不到app.py，但是这个文件肯定在根目录下。

其他详细信息从 Azure Container Registry 拉取镜像并运行它可以在我的本地机器和其他测试过它的机器上运行。

我有另一个带有 Node.JS 的 web 应用程序，当以完全相同的方式运行时（单击 Container Repo Tag X -> Deploy as App Service），它可以工作。

Azure App Service好像可以拉取镜像。 我的密码、用户名和存储库名称在文档中都是正确的。

图像已通过 Azure DevOps 构建和部署，就像我的 Node.JS web 应用程序一样，运行良好。 我也在本地构建了镜像，上传到Azure Container Registry也没有用。

如果图像在您的本地计算机上工作，我建议您检查应用程序服务中配置下的应用程序设置。

尝试以下设置

• WEBSITES_ENABLE_APP_SERVICE_STORAGE=false

我有一个 do.net 核心应用程序无法在 App Service 上运行，但是当我添加此环境变量时，它可以正常工作。 此变量表示您没有对容器使用持久卷。
