Turning off Amazon ECS cluster auto scaling - Amazon Elastic Container Service

Turning off Amazon ECS cluster auto scaling

You turn off cluster auto scaling when you need more granular control of the EC2 instances that are registered to your cluster,

To turn off cluster auto scaling for a cluster, you can either disassociate the capacity provider with managed scaling turned on from the cluster or update the capacity provider to turn off managed scaling.

Disassociate the capacity provider

Use the following steps to disassociate a capacity provider with a cluster.

  1. Use the put-cluster-capacity-providers command to disassociate the Auto Scaling group capacity provider with the cluster. The cluster can keep the association with the AWS Fargate capacity providers. For more information, see put-cluster-capacity-providers in the AWS CLI Command Reference.

    aws ecs put-cluster-capacity-providers \ --cluster ClusterName \ --capacity-providers FARGATE FARGATE_SPOT \ --default-capacity-provider-strategy '[]'

    Use the put-cluster-capacity-providers command to disassociate the Auto Scaling group capacity provider with the cluster. For more information, see put-cluster-capacity-providers in the AWS CLI Command Reference.

    aws ecs put-cluster-capacity-providers \ --cluster ClusterName \ --capacity-providers [] \ --default-capacity-provider-strategy '[]'
  2. Use the describe-clusters command to verify that the disassociation was successful. For more information, see describe-clusters in the AWS CLI Command Reference.

    aws ecs describe-clusters \ --cluster ClusterName \ --include ATTACHMENTS

Turn off managed scaling for the capacity provider

Use the following steps to turn off managed scaling for the capacity provider.

  • Use the update-capacity-provider command to turn off managed auto scaling for the capacity provider. For more information, see update-capacity-provider in the AWS CLI Command Reference.

    aws ecs update-capacity-provider \ --capacity-providers CapacityProviderName \ --auto-scaling-group-provider managedScaling=DISABLED
