Trello Overseer
Trello overseer finds the latest Drupal and WordPress releases and move Trello cards (our way of tracking the state of clients sites as 040.se) to the to-update list/column if there's a new minor version.
The setup for this project is a python application in a docker container that's deployed to AWS ECR and then run on AWS Lambda with a CloudWatch rule triggering it once a day. The infrastructure is provisioned using Terraform.
