错误：（gcloud.app.deploy）使用自定义运行时时必须提供自己的 Dockerfile

Question

我正在尝试使用 App Engine 在 Google Cloud 上安排 R 作业。我正在关注这篇文章

https://code.markedmondson.me/4-ways-schedule-r-scripts-on-google-cloud-platform/

但是，当我尝试使用部署应用程序时，gcloud app deploy --project shiny-demo出现以下错误

Enabling service [appengineflex.googleapis.com] on project [shiny-demo]...
Waiting for async operation operations/acf.33c5e6da-6f9e-4e66-b7d3-f0611eddc0ce to complete...
Operation finished successfully. The following command can describe the Operation details:
 gcloud services operations describe operations/tmo-acf.33c5e6da-6f9e-4e66-b7d3-f0611eddc0ce
Beginning deployment of service [default]...
ERROR: (gcloud.app.deploy) You must provide your own Dockerfile when using a custom runtime. Otherwise provide a "runtime" field with one of the supported runtimes.

我的 yaml 文件在同一文件夹中确实有一个 Dockerfile，但不知何故它无法识别该 Dockerfile。下面是我的 yaml 文件：

Enabling service [appengineflex.googleapis.com] on project [shiny-demo]...
Waiting for async operation operations/acf.33c5e6da-6f9e-4e66-b7d3-f0611eddc0ce to complete...
Operation finished successfully. The following command can describe the Operation details:
 gcloud services operations describe operations/tmo-acf.33c5e6da-6f9e-4e66-b7d3-f0611eddc0ce
Beginning deployment of service [default]...
ERROR: (gcloud.app.deploy) You must provide your own Dockerfile when using a custom runtime. Otherwise provide a "runtime" field with one of the supported runtimes.

我的 Dockerfile：

# DOCKER

COPY [".", "./"]

EXPOSE 8080
ENTRYPOINT ["R", "-e", "pr <- plumber::plumb(commandArgs()[4]); pr$run(host='0.0.0.0', port=8080)"]
CMD ["myscript.R"]

我对 Docker 有点陌生。

您的 Dockerfile 名称是Dockerfile（首字母大写）吗？

Windows 有时会在内部将文件另存为.txt.

创建的 Dockerfile 必须不带扩展名。要在 Windows 中执行此操作，请使用您选择的编辑器创建文件，然后使用符号“Dockerfile”（包括引号）保存它。

您的 Dockefile 是否位于与 相同级别的正确路径app.yaml中？
