lambder-set-cwl-expirations

set-cwl-expirations is an AWS Lambda function for use with Lambder.

It will iterate through all CloudWatch Logs created by Lambdas and will set a one week retention policy on any that do not already have a policy.

REQUIRES:

• python-lambder

Getting Started

1. Test the sample lambda function

   python lambda/set-cwl-expirations/set-cwl-expirations.py

2. Deploy the sample Lambda function to AWS

   lambder functions deploy

3. Invoke the sample Lambda function in AWS

   lambder functions invoke --input input/ping.json

4. Add useful code to lambda/set-cwl-expirations/set-cwl-expirations.py

5. Add any permissions you need to access other AWS resources to iam/policy.json

6. Update your lambda and permissions policy in one go

   lambder functions deploy

Sharing your lambder function

If you decide to share your lambder function, you want to be sure you don't share the name of your s3 bucket. We suggest you add lambder.json to your .gitignore so it won't be commited to your repo. Instead, copy it to example_lambder.json and remove any secrets before pushing to a public repository.

Using virtualenvwrapper

Your Lambdas should be as small as possible to reduce spinup time. If you need to include extra python modules, use virtualenvwrapper. The deploy script will look for a site-packages directory in $WORKON_HOME/lambder-set-cwl-expirations and bundle those packages into the zip that it uploads to AWS Lambda.
