How do I resolve Amazon ECS service quota issues?

Resolution

Amazon ECS has service quotas for maximum resources in each AWS Region in each AWS account. If you exceed these quotas, then you can't create new resources and you receive the "Limit exceeded" error.

To resolve service quota issues, check your Amazon ECS resource usage.

Then, take the following actions:

• Delete outdated versions of the task definition.
• Delete Amazon ECS services that have no active tasks or current usage.
• Delete unused Amazon EC2 Auto Scaling group capacity providers.

Use cluster auto scaling to allow Amazon ECS to dynamically adjust the number of required container instances based on workload demands. To optimize cluster auto scaling, set scaling metrics and thresholds based on your application's needs. Configure Amazon ECS service auto scaling to automatically adjust the desired task count in your service based on demand.

If you optimized your resources and still exceed the quotas, then you can request a quota increase.

Important: Not all service quotas are adjustable. Before you submit a request, check whether you can adjust the resource quota.
