- Create Project
-
Activate cloud shell
-
Run describe
verify project is working
gcloud projects describe $GOOGLE_CLOUD_PROJECT
output of command:
createTime: '2019-05-29T21:21:10.187Z'
lifecycleState: ACTIVE
name: helloml
projectId: helloml-xxxxx
projectNumber: '881692383648'
- You may want to verify you have the correct project and if not, do this to switch:
gcloud config set project $GOOGLE_CLOUD_PROJECT
- Create app engine app:
gcloud app create
this will ask for the region. Go ahead and pick us-central [12]
Creating App Engine application in project [helloml-xxx] and region [us-central]....done.
Success! The app is now created. Please use `gcloud app deploy` to deploy your first app.
- Clone the hello world sample app repo:
git clone https://github.com/GoogleCloudPlatform/python-docs-samples
- cd into the repo:
cd python-docs-samples/appengine/standard_python37/hello_world
- Update Cloudshell image [NOTE this is optional....you don't need this]
git clone https://github.com/noahgift/gcp-hello-ml.git
# Update .cloudshellcustomimagerepo.json with project and image name
# TIP: enable "Boost Mode" in in Cloudshell
cloudshell env build-local
cloudshell env push
cloudshell env update-default-image
# Restart Cloudshell VM
- create and source the virtual environment:
virtualenv --python $(which python) venv
source venv/bin/activate
double check it works:
which python
/home/noah_gift/python-docs-samples/appengine/standard_python37/hello_world/venv/bin/python
- activate cloud shell editor
- install packages:
pip install -r requirements.txt
this should install flask
Flask==1.0.2
- run flask locally
this runs flask locally in gcp shell
python main.py
- preview
- update main.py
from flask import Flask
from flask import jsonify
app = Flask(__name__)
@app.route('/')
def hello():
"""Return a friendly HTTP greeting."""
return 'Hello I like to make AI Apps'
@app.route('/name/<value>')
def name(value):
val = {"value": value}
return jsonify(val)
if __name__ == '__main__':
app.run(host='127.0.0.1', port=8080, debug=True)
- Test out passing in parameters to exercise this function:
@app.route('/name/<value>')
def name(value):
val = {"value": value}
return jsonify(val)
For example, calling this route will take the word lion and pass into the name function in flask:
https://8080-dot-3104625-dot-devshell.appspot.com/name/lion
returns value in web browser:
{
value: "lion"
}
- Now deploy the app
gcloud app deploy
Warning first deploy could take about 10 minutes FYI!!! you may also need to enable cloud build API.
Do you want to continue (Y/n)? y
Beginning deployment of service [default]...

- Now stream the log files:

- The production app is deployed and should like this:
Setting traffic split for service [default]...done.
Deployed service [default] to [https://helloml-xxx.appspot.com]
You can stream logs from the command line by running:
$ gcloud app logs tail -s default

- Add a new route and test it out
@app.route('/html')
def html():
"""Returns some custom HTML"""
return """
<title>This is a Hello World World Page</title>
<p>Hello</p>
<p><b>World</b></p>
"""
- Install pandas and return json results
At this point, you may want to consider creating a Makefile and do this:
touch Makefile
#this goes inside that file
install:
pip install -r requirements.txt
you also may want to setup lint:
pylint --disable=R,C main.py
------------------------------------
Your code has been rated at 10.00/10
Route looks like this:
add pandas import at top:
import pandas as pd
@app.route('/pandas')
def pandas_sugar():
df = pd.read_csv("https://github.com/raw/noahgift/sugar/master/data/education_sugar_cdc_2003.csv")
return jsonify(df.to_dict())
When you call the route https://<yourapp>.appspot.com/pandas
you should get something like this:
21.Add this wikipedia route
import wikipedia
@app.route('/wikipedia/<company>')
def wikipedia_route(company):
result = wikipedia.summary(company, sentences=10)
return result
- Add NLP to app:
A. https://github.com/noahgift/recommendations/blob/master/notebooks/NLP_GCP.ipynb
B. Enable Cloud Natural Language API
C. pip install google-cloud-language
test it out in IPython
In [1]: from google.cloud import language
In [2]:
In [2]: text = "LeBron James plays for the Cleveland Cavaliers."
...: client = language.LanguageServiceClient()
...: document = language.Document(
...: content=result,
...: type_=language.Document.Type.PLAIN_TEXT)
...: encoding_type = language.EncodingType.UTF8
...: entities = client.analyze_entities(request = {'document': document, 'encoding_type': encoding_type}).entities
