app.py TypeError('port must be an integer') error

[0xlen]

Hi Abby,

Thanks for your good tutorial for ecs demo.

When building the docker image for ecs-demo-web and ecs-demo-api:

$ cd <path/to/project>/ecs-demo/web
$ docker build -t ecs-demo-web .
$ cd <path/to/project>/ecs-demo/api 
$ docker build -t ecs-demo-api .

In the app.py, it specifies the string as the port number, this may occur the type error when running the docker image.

ecs-demo/web/app.py

Line 9 in ed773df

app.run(port='3000',host='0.0.0.0')

ecs-demo/api/app.py

Line 9 in ed773df

app.run(port='8000',host='0.0.0.0')

Error output

Traceback (most recent call last):
  File "app.py", line 9, in <module>
    app.run(port='8000',host='0.0.0.0')
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 772, in run
    run_simple(host, port, self, **options)
  File "/usr/local/lib/python2.7/dist-packages/werkzeug/serving.py", line 748, in run_simple
    raise TypeError('port must be an integer')

I open a PR to fix this issue and hope it helps.

Here are related flask official issue discussing about this case.

• app.run(port='5000', debug=True) error
  app.run(port='5000', debug=True) error pallets/flask#2220

• Raise TypeError if port is not an integer
  Raise TypeError if port is not an integer pallets/werkzeug#1088

Change port type from string to integer works fine.
app.run(port=3000,host='0.0.0.0')
