Mounting AWS EFS to ECS EC2 Container - amazon-web-services

Question

Hello I'm using Terraform to try and spin up Zookeeper for a development environment and I keep running into the following issue when I spin up the terraform.
Stopped reason Error response from daemon: create
ecs-clearstreet-basis-dev-Zookeeper-46-clearstreet-confluent-c2cf998e98d1afd45900:
VolumeDriver.Create: mounting volume failed: Specified port [2999] is
unavailable. Try selecting a different port.
I don't have this issue when attaching an EFS to a Fargate container.
Here is the terraform for reference.
