I was hoping to see a bit more of an explanation of how this was implemented.

Regarding the alb-ingress-controller blackholing traffic with an IP target type ingress, check out support for pod readiness gates: https://kubernetes-sigs.github.io/aws-alb-ingress-controller.... Assuming you're using a rolling deployment, old pods won't be stopped until the new ones are added to the ALB target group and are in a healthy state. This has eliminated the small number of ELB 500s we'd see on deploys.
If you ever open-source your rightsizing scripts, I think a lot of people (including myself) would find that useful. While the vertical pod autoscaler attempts to solve this problem, it's incompatible with horizontal pod autoscalers based on CPU and memory, and thus unusable in a lot of cases. Going with a semi-automated solution might be ideal.
