# Severless GraphQL API with Django and Graphene

## Setup Guide

1. Virtualenv with Python 3.6

   ```

   $ python3.6 -m venv env_django-lambda

   $ source env_django-lambda/bin/activate

   ```

   > Zappa currently supports only Python 3.6

2. Install requirements.txt

   ```

   $ pip3 install -r requirements.txt

   ```

3. Set up RDS in my_django_proejct/settings.py (using already existing RDS instance)

   > postgreSQL

   ```python

   DATABASES = {

     'default': {

     'ENGINE': 'django.db.backends.postgresql_psycopg2',

     'NAME': 'db_name',

     'USER': 'user_name',

     'PASSWORD': 'rds_master_password',

     'HOST': 'something.rds.amazonaws.com',

     'PORT': '5432',

     }

   }

   ```

4. Valid AWS account and Create IAM user with role for zappa

- Create IAM user for lambda

  - Permissions policies

    - AWSLambdaFullAccess

    - IAMFullAccess

    - AmazonAPIGatewayAdministrator

    - AWSCloudFormationReadOnlyAccess

    - Creating **custom policy** for only zappa

    ```

    {

      "Version": "2018-10-18",

      "Statement": [

        {

          "Sid": "my_project_zappa_1",

          "Effect": "Allow",

          "Action": [

            "cloudformation:CreateStack",

            "cloudformation:CreateChangeSet",

            "cloudformation:ListStacks",

            "cloudformation:UpdateStack",

            "cloudformation:DescribeStacks",

            "cloudformation:DescribeStackResource",

            "cloudformation:DescribeStackEvents",

            "cloudformation:ValidateTemplate",

            "cloudformation:DescribeChangeSet",

            "cloudformation:ExecuteChangeSet"

          ],

          "Resource": [

            "*"

          ]

        }

      ]

    }

    ```

5. Initializing Zappa

   $ zappa init

   ```

6. Edit zappa_settings.json
