aws-lambda-version-api-pipeline

Brian Jopling, September 2020

Description

Contains the CloudFormation infrastructure as code for a CICD Pipeline that deploys both infra and code changes to an API. The API consists of an API Gateway whose Stages are backed by different Lambda Versions & Aliases.

This project expects there to be 3 different accounts: a Dev, Prod, and Tools. The Tools account is where the CICD Pipeline resides in, which uses cross-account IAM roles to perform deployments in Dev & Prod.

Usage Steps

1. In Tools Account, deploy tooling-prereq.yaml with CodeBuildCondition parameter set to false.
2. In Dev Account, deploy dev-prereq.yaml.
3. In Tools Account, deploy toolings.yaml with CrossAccountCondition set to false.
4. Create a change set for the stack created in step “1” (tooling-prereq.yaml) with the CodeBuildCondition parameter set to true.
5. Create a change set for the stack created in step “3” (toolings.yaml) with CrossAccountCondition set to true.
