I was learning about lifecycle hooks recently. Before I added my own, I thought I'd do some research in the lifecycle hooks available. I was hoping to find a simple terraform module lambda for ECS. After some searching, I curated this list and thought "Why not another awesome list?" And the list was born.
Feel free to contribute.
