This module creates a lambda that will sync GitHub action binary to a S3 bucket, the lambda will be triggered via a CloudWatch event. The distribution is cached to avoid the latency of downloading the distribution during the setup. After deployment the lambda will be triggered via an S3 object created at deployment time.
Usage examples are available in the root module. By default the root module will assume local zip files containing the lambda distribution are available. See the download lambda module for more information.
The Lambda function is written in TypeScript and requires Node 12.x and yarn. Sources are located in [./lambdas/runners-binaries-syncer].
cd lambdas/runners
yarn install
Test are implemented with Jest, calls to AWS and GitHub are mocked.
yarn run test
To compile all TypeScript/JavaScript sources in a single file ncc is used.
yarn run dist
