StartTask V/S RunTask in Fargate

Question

I was writing AWS IAM permissions. Our use case is only AWS Fargate. After reading the documentation it seems like StartTask is not required for AWS fargate but I will need to give permissions for RunTask. Could not find any document related to this?

Can anybody confirm/point to the docs?

Thanks

See documentation here In your case you have to use RunTask

Run Task API

The RunTask action is ideally suited for processes such as batch jobs that perform work and then stop. For example, you could have a process call RunTask when work comes into a queue. The task pulls work from the queue, performs the work, and then exits.

Start Task API

Custom schedulers use the StartTask API operation to place tasks on specific container instances within your cluster.

Custom schedulers are only compatible with tasks using the EC2 launch type. If you are using the Fargate launch type for your tasks, the StartTask API does not work.
