Permission denied during gcloud app deploy using Google Cloud SDK - google-app-engine

Question

It is insanely hard, to deploy an app to Google App Engine, using Google Cloud SDK.
I had tried the below 2 commands
C:\Users\yccheok\Desktop\jstock-android-appengine>gcloud config set project jstock-android
Updated property [core/project].
C:\Users\yccheok\Desktop\jstock-android-appengine>gcloud app deploy app.yaml --log-http --verbosity=debug

Then, I went through https://cloud.google.com/appengine/docs/admin-api/accessing-the-api , it mentioned I need to use Admin API. So, I do it step by step carefully.
Step 1
Step 2
It mentions Admin API is enabled. Now I need credential.
Step 3
Step 4
OK. Now they mention I don't need create new credential. I can use Application Default Credentials ?!
Step 5
So, I went to https://developers.google.com/identity/protocols/application-default-credentials?hl=en_GB . I learn that I need to run
C:\Users\yccheok\Desktop\jstock-android-appengine>gcloud auth application-default login
Your browser has been opened to visit:
https://accounts.google.com/o/oauth2/auth?redirect_uri=http%3A%2F%2Flocalhost%3A8085%2F&prompt=select_account&response_type=code&client_id=764086051850-6qr4p6gpi6hn506pt8ejuq83di341hur.apps.googleusercontent.com&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcloud-platform&access_type=offline
Credentials saved to file: [C:\Users\yccheok\AppData\Roaming\gcloud\application_default_credentials.json]
These credentials will be used by any library that requests
Application Default Credentials.
Step 6
Step 7
Still, after completing the above 7 steps, I still get the exact same error message, when trying to run
gcloud app deploy app.yaml --log-http --verbosity=debug
Can anyone let me know, what step I'm still require, in order to deploy my Python app to Google App Engine, using Google Cloud SDK?

Answer 1

The Admin API is for programmatically deploying the app, not for deploying using gcloud app deploy, for which you don't even need the Admin API enabled for your app.
From Deploying a Python App:
To programmatically deploy your apps, use the Admin API.
Before you begin
Before you can deploy your app:
The Owner of the GCP project must create the App Engine application.
Ensure that your user account includes the required privileges.
(but I can see how the above could be mis-intrepreted as an invitation to use the Admin API)
Most likely the account actually used by gcloud app deploy is missing or doesn't have the required permissions.
You can check the acount used with gcloud auth list. In my case the account is my email address, not a service account (I'm not sure if a service account can be used).
Use gcloud auth login (and maybe gcloud auth revoke) if you need a different account.
And you can check the account's privileges (if any) on the project/app on the IAM Page.

Answer 2

One additional note on this,
When you enable the App Engine API and the cloud builder api, make sure the Cloud Build Service Account also has access to the project.
I ran into that problem after enabling the correct apis.
This was using a build trigger. I could deploy locally from a command line because I was authenticated as myself. However, if you are using a build trigger, it will use the build service account, which needs access.
Hope this helps.

Answer 3

I had this issue. In my case it was solved by setting the project using the project ID, rather than the project name. See this answer
gcloud app deploy ERROR: Permissions error fetching application [apps/<PROJECT_NAME>]
