App Engine Flexible Environment - Dockerfile安装了GDAL的过时版本。

Question

我正试图在Google App Engine Flexible Environment上使用Docker镜像。

FROM ubuntu:bionic
MAINTAINER Makina Corpus "[email protected]"

ENV PYTHONUNBUFFERED 1
ENV DEBIAN_FRONTEND noninteractive
ENV LANG C.UTF-8

RUN apt-get update -qq && apt-get install -y -qq \
    # std libs
    git less nano curl \
    ca-certificates \
    wget build-essential\
    # python basic libs
    python3.8 python3.8-dev python3.8-venv gettext \
    # geodjango
    gdal-bin binutils libproj-dev libgdal-dev \
    # postgresql
    libpq-dev postgresql-client && \
    apt-get clean all && rm -rf /var/apt/lists/* && rm -rf /var/cache/apt/*

# install pip
RUN wget https://bootstrap.pypa.io/get-pip.py && python3.8 get-pip.py && rm get-pip.py
RUN pip3 install --no-cache-dir setuptools wheel -U

CMD ["/bin/bash"]

docker镜像似乎正确构建，但当服务部署时，应用程序崩溃，我得到这个错误信息。

  File "/Users/NAME/Documents/gcp/google-cloud-sdk/lib/googlecloudsdk/api_lib/app/operations_util.py", line 183, in IsDone
    encoding.MessageToPyValue(operation.error)))
OperationError: Error Response: [9] 
Application startup error! Code: APP_CONTAINER_CRASHED

ERROR: (gcloud.app.deploy) Error Response: [9] 
Application startup error! Code: APP_CONTAINER_CRASHED

这是失败的，因为Dockerfile安装了一个明显过时的GDAL包的版本，这与当前的python安装冲突。

我如何确保Dockerfile有正确的包库，并且安装的是正确的、最新的版本？有没有什么行可以让我在开始安装之前插入更新版本库，或者至少打印版本库？

EDIT:

我的app. yaml:

# [START django_app]

runtime: custom
env: flex
entrypoint: gunicorn -b :$PORT MyApplication.wsgi

runtime_config:
  python_version: 3
# [END runtime]

handlers:
# This configures Google App Engine to serve the files in the app's static
# directory.
#- url: /static
#  static_dir: static/
#- url: /MyApplication/static
#  static_dir: MyApplication/static/


# This handler routes all requests not caught above to your main app. It is
# required when static routes are defined, but can be omitted (along with
# the entire handlers section) when there are no static files defined.
- url: /.*
  script: auto
# [END django_app]

你的App Engine部署失败了，因为它 需要一个服务监听端口8080 并且它无法在云端运行bash。如果你需要调试你的App Engine Flex实例，你需要先在8080端口上获得一个服务。然后启用SSH.
