When creating a new AWS ECS service using a Fargate task, in the AWS Console wizard, it fails with the following error:

Failed creation of Service
Service creation failed: The specified platform does not satisfy the task definition’s required capabilities.

The service launch type is set to FARGATE and the Platform version is set to LATEST. The task is attempting to mount an AWS EFS filesystem for persistent storage (introduced in version 1.4.0 of the platform).

This is by design because AWS have yet to upgrade LATEST to point to v1.4.0 (as per 2020-06-23, see AWS ECS Developer Guide). Set the service platform version explicitly to 1.4.0 (instead of LATEST).


It doesn't tell the exact error message, however in my case,

I was using firelens log driver with S3 configuration type. Since Fargate only supports local file at this point, I got the same error message. Once I changed it to local file in the task definition json, it proceeded further.

  • ty, it wasn't the problem in this case but could be helpful for someone else.
