How to run aws cli command on Google Cloud Function - google-app-engine

I have an access with aws.
Is this possible to do the following
Google Cloud Function can run aws-cli commands.
Google App Engine can kick actions of aws-cli commands.
For example:
#!/usr/bin/env python
import subprocess
import sys
import awscli.clidriver
def aws_demo(request):
cmd = 'aws s3 ls'
result = subprocess.run(
cmd.split(" "),
stdout=subprocess.PIPE,
stderr=subprocess.STDOUT
)
print(result.stdout.decode())
return str(result.stdout.decode())
Error :
Traceback (most recent call last):
File "/env/bin/aws", line 19, in <module>
import awscli.clidriver
ModuleNotFoundError: No module named 'awscli'

Google Cloud Function can run aws-cli commands?
The command-line AWS tools aren't available or installable in Google Cloud Functions. Your best bet is to use the boto3 Python package instead as John suggested.
As far as managing credentials within boto3 is concerned, there are a number of ways to configure credentials, as described here.
Google App Engine can kick actions of aws-cli commands?
I think as with the Google Cloud Function, is not possible to run AWS command using the command line tool awscli.
I would highly recommend to also use boto3 as it will keep your infrastructure equal among the different GCP products.
I hope it helps.

No module named 'google.appengine' from within Cloud Shell

I'm testing Google App Engine and trying to run a simple function to upload files to either the Blobstore or Cloud Storage. I'm typing the Python code directly in the Cloud Shell of my instance. The code is failing when I call:
from google.appengine.ext import blobstore
I get the error code:
Traceback (most recent call last):
File "upload_test.py", line 1, in <module>
from google.appengine.api import users
ImportError: No module named 'google.appengine'
Even though the documentation says that: You can use Google Cloud Shell, which comes with git and Cloud SDK already installed, I've tried installing a bunch of libraries:
gcloud components install app-engine-python
pip install google-cloud-datastore
pip install google-cloud-storage
pip install --upgrade google-api-python-client
I'm still getting the same error. How can I get the appengine library to work? Alternatively, is this the wrong method for creating an app that allows the user to upload files?
The google.appengine module is baked into the first-generation Python (2.7) runtime. It's not available to install via pip, in the second-generation (3.7) runtime, or in Cloud Shell.
The only way to use it is by writing and deploying a first-generation App Engine app.
Thanks #Dustin Ingram
I found the answer in this page.
The current "correct" way of uploading to Cloud Storage is to use google.cloud.storage. The tutorial I linked above explains how to implement it.
The impression I have, however, is that this uses twice the bandwidth as the solution via google.appengine. Originally, the front-end would receive an upload url and send the file directly to the Blobstore (or to Cloud Storage). Now the application uploads to the back-end which, in turn, uploads to Cloud Storage.
I'm not too worried, as I will not be dealing with excessively large files, but it seems strange that the ability to upload directly has been discontinued.
In any case, my problem has been solved.

ImportError: cannot import name cygrpc on development Google App Engine with Firebase Cloud Firestore

I am building a RESTful API using Python 3.6, the Falcon Framework, Google App Engine, and Firebase Cloud Firestore. At runtime I am receiving the following error ...
File "E:\Bill\Documents\GitHubProjects\LetsHang-BackEnd\lib\google\cloud\firestore_v1beta1\_helpers.py", line 24, in <module> import grpc
File "E:\Bill\Documents\GitHubProjects\LetsHang-BackEnd\lib\grpc\__init__.py", line 22, in <module>
from grpc._cython import cygrpc as _cygrpc
ImportError: cannot import name cygrpc
When researching StackOverFlow, I found an article regarding an AWS Lambda deployment, but it suggests a solution based on Docker. Docker is not a viable solution for us. I also found an article off StackOverflow that suggests running "pip install grpcio". We did not without luck.
We build the App Engine dependencies using a requirements.txt file. This file has the following contents ...
falcon==1.4.1
google-api-python-client
google-cloud-firestore
firebase-admin
enum34
grpcio
We apply the requirements file using the command ...
pip install -t lib -r requirements.txt
The App Engine server is started with the command ...
dev_appserver.py .
The development environment is Windows 10.
You seem to be mixing up the GAE standard and flexible environments:
using Python 3.6 is only possible in the flexible environment (which, BTW, is fundamentally Docker-based)
installing app dependencies in the lib directory and using dev_appserver.py for local development are only applicable to the standard environment
Somehow related: How to tell if a Google App Engine documentation page applies to the standard or the flexible environment
Ok. I will write up my findings just in case there's another fool like me.
First, Dan's response is correct. I was mixing standard and flexible environments. I had looked up a method for using the Falcon Framework with App Engine; as it turns out, the only article uses the standard environment. So that's how I wound up using dev_appserver.py. My app, however, is Python 3.6 and has dependencies that prevent stepping down to 2.7.
To develop locally for the flexible environment, you simply need to run as you normally would. In the case of Falcon Framework, that means using the Waitress wsgi server.
I find that it is a good practice to build and use a Python virtual environment. You use the virtualenv command for that. At deployment time, Google builds a docker container for the app in the cloud. To reconstruct all the necessary Python packages, you have to supply a requirements.txt file. If you have a virtual environment, then the requirements file is easily produced using pip freeze.

Using Google Cloud Client Library and Google App Engine SDK Together

I am trying to use the Google Cloud Client Library on Google App Engine. However, the Cloud Client Library and the App Engine SDK use google as an import name, and there are naming conflicts. How do I get them to work together?
When I try importing a Google Cloud Client Library module, I get the following error:
>> import google.cloud.datastore
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "C:\[...]\libs\google\cloud\datastore\__init__.py", line 52, in <module>
from google.cloud.datastore.batch import Batch
ImportError: No module named cloud.datastore.batch
The reason this import error occurs is because the name google has already been imported from the App Engine SDK. This can be confirmed by running the command:
>>> print google.__path__
['C:\\Program Files (x86)\\Google\\Cloud SDK\\google-cloud-sdk\\ platform\\google_appengine\\google']
Notice that the path points to the SDK.
Any ideas on how to resolve this name conflict?

ImportError: No module named google.appengine.ext.webapp.mail_handlers

I'm trying to get google app engine to work on my Raspberry Pi. I keep getting this error.
Traceback (most recent call last):
File "main.py", line 26, in <module>
from google.appengine.ext.webapp.mail_handlers import InboundMailHandler
ImportError: No module named google.appengine.ext.webapp.mail_handlers
I downloaded google app engine and then ran these commands:
unzip google_appengine_1.9.40.zip
export PATH=$PATH:/home/pi/google_appengine/
The most trivial solution for such errors is to import the required package into you project directory. but to be honest it is not the best way to resolve this one. you may use Google App Engine SDK which will take care of all that headache, or there are another way you can follow:
Create a folder into your project directory and call it lib
Add all required packages into this folder.
Create a .py file and name it appengine_config.py
Add the below code snippets into this file:
import sys
import os.path
sys.path.insert(0, os.path.join(os.path.dirname(__file__), 'lib'))
appengine_config.py gets loaded every time a new instance is started, and should take care of your modules importing.
Regards.
It appears you're trying to directly execute your main.py as a standalone application, which is not how GAE app code works.
You're supposed to get the development server (from the SDK you downloaded) to execute your app code on your development machine (on GAE it's the GAE infra doing that). See Using the Local Development Server.

Google app engine and prediction API (error import)

Please help me to solve this error? I'm doing this exercise on app engine (https://developers.google.com/appengine/articles/prediction_service_accounts) , but I'm stuck in step 6.2 because I raise this error(When I run the deploy operation, it is successful step 6.1):
: No module named appengine
Traceback (most recent call last):
File "/base/data/home/apps/s~01prediction/1.367567721220366691/main.py", line 29, in
from oauth2client.appengine import AppAssertionCredentials
The error in line 29 :
from oauth2client.appengine import AppAssertionCredentials
Did you run step 3.2? That should have copied some folders into prediction-demo-skeleton. You should have a folder called oauth2client inside prediction-demo-skeleton. Take a look at the folders that are inside prediction-demo-full.
ps: a good practice before deploying is to run your app using the devappserver.
The Google API Python Client now has a pre-packaged ZIP containing all dependencies that might make installation easier. See:
https://code.google.com/p/google-api-python-client/downloads/list
Select google-api-python-client-gae-1.1.zip for download. Unzip this file inside of your AppEngine app directory.
Along the lines of Sebastian's suggestion it generally is a good idea to test locally using the devappserver. In this case you should be able to get past the import issue, however AppAssertionCredentials won't actually be able to generate any access tokens until it is deployed into a production environment, so it will be of limited use for you.
