如何使用Go运行时将exe文件复制到App Engine（flex）？

My Go application needs to use a stand-alone executable, which I would like to copy it along with 'gcloud app deploy' command during deployment to GAE flex environment.

  1. I have tried keeping the exe in the folder where other go files are located during deploy, but this doesn't seem to take the exe to the GAE flex
  2. I tried using these 2 lines in Dockerfile and changed the "runtime: custom" in app.yaml, but that didn't fix either, as I am missing few more things it seems.
FROM gcr.io/google-appengine/golang 
ADD test.exe /usr/local/bin/

Can anyone suggest, without/with Dockerfile, how can I copy the test.exe and also build the go application on a GAE flex environment?

EDIT: I realize I should install the package (Debian package) on the GAE machine itself, and make it available for the App Engine app.

Any pointers on how to prepare the Dockerfile so that the Debian package is installed with all its dependencies and is also accessible to the app that I am deploying to App Engine?

You can copy a file using the command COPY.

However, it will not work, since the VM running the GAE flex instance uses Linux as seen in StackOverflow.

I also found this related thread, it may be helpful for you.

EDIT

Other options you have to deploy your application, which is in need of a windows executable file, is to create a VM instance with Windows and deploy your application there. Or you could find an alternative for that stand-alone executable for Linux, perhaps?
