Summary: Evolution of project 7 realized during the OpenClassrooms course with : Zappa, AWS Lambda & Gitlab-CI/Pages.
Lang: en

Tags: git, gitlab, devops, flask, dev, zappa, serverless, aws, ci, cd, aws-lambda, python,

This was a [student project][oc] previously hosted on [Github][ocp7]. I updated it to play with :

* [Zappa][zappa]
* [Flask][flask]
* [AWS Lambda][awslmbd]
* [Gitlab-ci][glci]

It is a _robot_ grandfather talking about geographic memories and quoting Wikipedia fetching data over public APIs.

If you can speak French, [have a talk with him][prod] (^_^)

Run yours !
-----------

Need some environment variables to run :

- `EMAIL_ADDRESS` (Nominatim API)
- `MAPBOX_API_KEY` (Mapbox API)
- `GOO_API_KEY` (not used [but needed][issue51])


### Locally :

It works as a simple single-page [Flask][flask] application :

- [fork-it][fork]
- set up a virtualenv : `virtualenv .venv`
- install requirements : `pip install -r requirements.txt`
- run it locally : `python run.py`

### On Gitlab :

Set up a [AWS IAM profile][awsiam] on **your AWS account** and add valid environment variables in `https://gitlab.com/<namespace>/grandpy/settings/ci_cd` :

- `AWS_ACCESS_KEY_ID`
- `AWS_SECRET_ACCESS_KEY`

Push it back and the _CI script_ will :

- put chat code on [AWS Lambda][awslmbd] with the magic of [Zappa][zappa]
- edit [JavaScript][js] with the URL of the _AWS API Gateway_ just updated
- generate the HTML landing page (with a [flask script][genstat])
- deploy statics on _gitlab-pages_ (HTML, images & CSS)

…and _voilà_, have a chat with _GrandPy_ on `https://<namespace>.gitlab.io/grandpy/` (-;
