I have a use case where I want to connect and query an AWS DocumentDB cluster from a containerized application deployed in an AWS ECS cluster (Fargate launch-type).
I already have a Task IAM Role defined and I would like to use it for connecting to DocumentDB instead of using a username/password combination.
Is the aforementioned scenario possible to achieve? If yes, how? After reading a lot about the topic, I didn’t find a reference on how I can achieve it. Also checked in AWS IAM console the possibility to create a custom Policy, but I didn’t find related to DocumentDB actions.
Any help would be greatly appreciated.
>Solution :
It appears at this time you will have to use username/password authentication to connect to DocumentDB. There is no support at this time for IAM authentication for connections to DocumentDB databases.
