This repository contains examples of AWS-related topics, typically examples from Chariot's blog. All code is licensed under Apache 2.0.

Each sub-directory is a distinct project, with a README that describes the project in more detail:

• cloudtrail_to_elasticsearch

  A Lambda that uploads CloudTrail events to an Elasticsearch cluster. Referenced by Delving into CloudTrail Events.

• cloudtrail_aggregation

  A Lambda-based pipeline to aggregate individual CloudTrail log files into daily and monthly versions. Also appropriate for use with other bursty data sources that produce large numbers of relatively small file (eg, Kinesis Firehouse pipelines).

• infrastructure-tools-comparison

  Examples for creating users, groups, and roles using CloudFormation, Cloud Development Kit (CDK), CFNDSL, and Terraform. Referenced by [Comparing Infrastructure Tools: A First Look at the AWS Cloud Development Kit)(https://chariotsolutions.com/blog/post/comparing-infrastructure-tools-a-first-look-at-the-aws-cloud-development-kit/).

• infrastructure-tools-comparison-2

  Comparison of Terraform modules and CDK custom constructs. This is a follow-on to the prior example.

• lambda_build_in_docker

  A skeleton Python Lambda that depends on the psycopg2 database library. Referenced by Building and Deploying Lambdas from a Docker Container.

• lambda_container_images

  A skeleton Lambda that depends on the psycopg2 database library and is deployed as a Docker container. Referenced by Getting Started with Lambda Container Images.

• sandbox-policies

  IAM and service control policies that Chariot uses for managing developer sandboxes. Referenced by Building Developer Sandboxes on AWS.

• springboot-secman-auth / springboot-iam-auth

  Examples of using connection-time credentials with Spring Boot. The first uses an AWSLabs driver library to retrieve credentials from Secrets Manager. The second uses a custom Postgres datasource implementation to retrieve IAM-generated credentials. Referenced by RDS Database Authentication with Spring Boot, parts one and two.

• two_buckets_and_a_lambda

  A Lambda-based application that allows users to upload files from a browser (showing two ways to accomplish them) and then process those files via a triggered Lambda. Referenced by Two Buckets and a Lambda: a pattern for file processing.

• untagged_ec2_cleanup

  A Lambda that will find EC2 instances that don't have the proper ownership tags and shutting them down. Referenced by Building Developer Sandboxes on AWS.
