# Python script to Lambda function

This is a project that turned the [aquabot Python script](https://github.com/opsdisk/aquabot) into an AWS Lambda function.

# Basic Setup

* CloudWatch Event trigger cron job in UTC: `cron(15 16 * * ? *)` - replaces time.sleep() in a while loop.

* No VPC

* Handler: `aquabot.lambda_handler`

* Role has `AWSLambdaBasicExecutionRole` and `AWSLambdaMicroserviceExecutionRole` policies

* Security Group: Outbound 443 only for data.edwardsaquifer.org and twitter.com

* Test event is an empty dictionary: `{}`

* Can read twitter_creds.json; tested with environment variables and that also worked.

# Create a .zip deployment package

The .zip file contains all the code and the additional libraries installed (through pip).

## No virtualenv

```bash

cd aquabot_lambda

pip3 install -r requirements.txt -t .

zip -qr9 ../lambdapackage.zip .

```

## virtualenv

* Easiest to create virtual environment in the parent folder of the project

* Then add site-packages directory after initially creating the zip folder

```bash

virtualenv -p python3 .venv

source .venv/bin/activate

pip install -r aquabot_lambda/requirements.txt

```

```bash

cd aquabot_lambda

zip -qr9 ../lambdapackage.zip .

cd $VIRTUAL_ENV/lib/python3.6/site-packages

zip -qru9 ../../../../lambdapackage.zip .

cd -

deactivate

```
