test's Introduction

Example lambda project

This project was created to provide an example on how to setup a CI pipeline to build, test, deploy a simple lambda function in AWS. It was built on osx and has some dependencies to get started.

AWS account
go-task - https://taskfile.dev/#/installation
docker - https://docs.docker.com/install
terraform - https://learn.hashicorp.com/terraform/getting-started/install.html
aws-cli - https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html

Getting started

Ensure you're an admin in the AWS account and install the dependencies following their respective install docs.
The taskfile.yml contains the execution bits. The list of targets can be found with task --list

task --list
task: Available tasks for this project:
* build: 	Run terraform init/apply cmds to "build" the project
and deploy a AWS apigateway and lambda function.

* ci: 			Run build, test, destroy tasks
* create_s3: 		Create a s3 bucket
* destroy: 		Teardown tf infrastructure
* package_lambda: 	Package up the python dependencies
* post_lambda: 		Post lambda function to s3
* test: 		Test terraform .tf files including integration tests.
The "{{.API_GATEWAY_URL}}" var is written by taskvars.tf
and made available by Taskvars.yml for a quick/dirty
integration test. Test tools:

tflint - linter for AWS provider-specific issues
terraform validate - syntax checker
curl - quick/dirty integration test utilizing dynamic variables

Lambda function

Since I have no production experience w/lambda I thought I'd put together a simple, single function project. It sets up a lambda function in python that queries Google for the terms "devops" and "cancer"
