AWS Janitor

A GitHub Action to cleanup AWS resources that have exceeded a TTL.

By default the action will not perform the delete (i.e. it will be a dry-run). You need to explicitly set commit to true.

It supports cleaning up the following services:

• EKS Clusters
• Auto Scaling Groups

Inputs

Name	Required	Description
regions	Y	A comma seperated list of regions to clean resources in. You can use * for all regions
allow-all-regions	N	Set to true if use * from regions.
ttl	Y	The duration that a resource can live for. For example, use 24h for 1 day.
commit	N	Whether to perform the delete. Defaults to false which is a dry run

Example Usage

jobs:
  cleanup:
    runs-on: ubuntu-latest
    name: Cleanup resource groups
    steps:
      - name: Cleanup
        uses: rancher-sandbox/aws-janitor@v0.1.0
        with:
            regions: eu-west-1
            ttl: 168h
        env:
            AWS_ACCESS_KEY_ID: {{secrets.AWS_ACCESS_KEY_ID}}
            AWS_SECRET_ACCESS_KEY: {{secrets.AWS_SECRET_ACCESS_KEY}}

Implementation Notes

It currently assumes that an instance of a service will have some form of creation date. This means that the implementation can be simpler as it doesn't need to adopt a "mark & sweep" pattern that requires saving state between runs of the action.
