Run development env under pyenv (https://github.com/yyuu/pyenv)

We will run Postgres and Redis inside docker and web app on local host (for easy debugging)

Prerequisites
- Install Docker Toolbox
- Create and start a 'dev' Docker machine
```
   docker-machine start dev
```
Run Postgres docker container
```
    docker-compose up -d postgres
```

Activate python env

    source ~/.pyenv/envs/3.4.3/bin/activate

Install required Python packages

    cd to project/web directory
    pip install -r requirements.txt

Load env variables

rename .env_example to .env and update credentials

    source .env
    export $(cat .env | xargs)

    # check env set correctly
    echo $SECRET_KEY

Setup Postgres database

Create a db named $DB_NAME in postgres (if not already created)
Run db migrations (we use https://github.com/miguelgrinberg/Flask-Migrate)

    python migrate.py db init           # only first time
    python migrate.py db revision --autogenerate
    python migrate.py db upgrade

    python web/create_db.py

Create an app to use

    python manage.py create_app --name "CloudPhotos"

Setup reverse proxy url to use for oAuth callbacks to localhost
- On a new shell, run:
```
    ~/dev/ngrok http 9001
```
- Verify access to reverse proxy url
  - e.g. http://ea9f2968.ngrok.io/activate
- Update PUBLIC_URL in web/config.py with reverse proxy url
- Update AWS with reverse proxy address
  - https://developer.amazon.com
  - Under allowed urls under security profiles / web settings
- Update mobile client with reverse proxy url
Run web app from pycharm
