I am experimenting with the AWS CLI for application-autoscaling, and wanted to view how making changes in the CLI were reflected in the AWS console.
I set register-scalable-target with new a new minimum and maximum. When I updated the same service in the AWS Console, why is there no option to set autoscaling minimum and maximum values?
Found the answer! The autoscaling page is not (yet?) available in the "New ECS Experience." If you switch to the "classic" experience by flipping the toggle in the upper-left corner to the off position, then edit the service, you will see the autoscaling page.
(The page will also show the values set with the AWS CLI 'application-autoscaling register-scalable-target' command.)
