I am trying to get an AWS Lambda function to run whenever a new image is pushed to an AWS container registry. I have created and tested the function which works fine. I have then created a simple CloudWatch event rule with the pattern:
which I believe will trigger on any event from ECR.
The rule has a target of the lambda function. The problem is the function is not called when a new image is pushed to the registry (or deleted etc). Nothing appears in the CloudWatch logs for the function. Is there something missing from the event rule or a way to diagnose what could be going wrong?
