Lambda Errors

This project provides an AWS Lambda based on this blueprint that captures a Cloudwatch alarm via SNS and publishes an alert to a Slack channel.

Prerequisites

• This project is tested against Python 3.7+ in CircleCI.

Getting Started

git clone git@github.com:GovWizely/lambda-errors.git
cd lambda-errors
mkvirtualenv -p /usr/local/bin/python3.8 -r requirements-test.txt errors

If you are using PyCharm, make sure you enable code compatibility inspections for Python 3.7/3.8.

Tests

python -m pytest

Configuration

• Define the Slack hook URL and channel as environment variables e.g. export hookUrl=hooks.slack.com/services/abc. This will allow you to run the Lambda locally.
• Define AWS credentials in either config.yaml or in the [default] section of ~/.aws/credentials. To use another profile, you can do something like export AWS_DEFAULT_PROFILE=govwizely.
• Edit config.yaml if you want to specify a different AWS region, role, and so on.
• Make sure you do not commit the AWS credentials to version control.

Invocation

lambda invoke -v
