Is your request related to a problem? Please describe.

Our team at Rapid7 uses images in order to run our lambdas, we also use a separate CICD tool (not terraform) in order to manage the latest version of those lambdas. We have several different work arounds that are more complicated to simply grab the latest container image being used from ECR.

Describe the solution you'd like.

We'd like a way to not have the image updated on terraform updates and applies (a dummy one can still be first provided) so that teams can effectively manage the container version of the lambda in separate CICD tools. This would be best done as a new boolean variable that turns this on or off

Describe alternatives you've considered.

We have executed custom scripts in order to gather the latest version of a container from ECR/ECS/EKS. These are more complicated ways and have dependencies on the machines these scripts run on.
