# Lambda function / Python to create athena partitions for Cloudtrail log between any given days.
# If you run this in AWS Lambda then it can't able to ceate all the partitions.
# Because lambda can run any functions up to 5mins. But create partition query will take avg 6 secs.
# I did a benchmark on lambda, it created upto 3 months of partitions on 16 regions.

Continuous deployment of React websites to Amazon S3

This sample includes a continuous deployment pipiline for websites built with React. We use AWS CodePipeline, CodeBuild, and SAM to deploy the application. To deploy the application to S3 using SAM we use a custom CloudFormation resource.

Files included

• buildspec.yml: YAML configuration for CodeBuild, this file should be in the root of your code repository
• configure.js: Script executed in the build step to generate a config.json file for the application, this is used to include values exported by other CloudFormation stacks (separate services of the same application).
• index.js: Custom CloudFormation resource that publishes the website to an S3 bucket. As you can see from the buildspec and SAM template, this function is located in a s3-deployment-custom-resource sub-folder of the repo
• app-sam.yaml: Serverless Application model YAML file. This configures the S3 bucket and the cu
