错误：（gcloud.app.deploy）您必须在使用自定义运行时提供自己的 Dockerfile

Question

我正在尝试使用 App Engine 在 Google Cloud 上安排 R 作业。我在关注文章

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

但是，当我尝试使用 gcloud app deploy --project shiny-demo 部署应用程序时，我收到以下错误

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 文件所在的文件夹中确实有一个 Dockerfile，但不知何故，它无法识别 Dockerfile。以下是我的 yaml 文件：

# app.yaml file
runtime: custom
env: flex

manual_scaling:
  instances: 1
resources:
  cpu: 1
  memory_gb: 0.5
  disk_size_gb: 10

env_variables:
  GCS_AUTH_FILE: authkey.json

我的 Dockerfile：

# DOCKER
FROM trestletech/plumber
LABEL maintainer="mark"
RUN export DEBIAN_FRONTEND=noninteractive; apt-get -y update \
 && apt-get install -y libcairo2-dev \
    libcurl4-openssl-dev \
    libgmp-dev \
    libpng-dev \
    libssl-dev \
    libxml2-dev \

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（第一个字母大写）吗？

Windows 有时会在内部将文件保存为 .txt。

A Dockerfile must be created with no extension. 要在 Windows 中执行此操作， 使用您选择的编辑器创建文件，然后使用 表示法“Dockerfile”（包括引号）。

您在right path 中的Dockefile 是否与app.yaml 处于同一级别？
