Auto Scaling:ModifyEciScalingConfiguration

Last Updated:Feb 08, 2024

Modifies scaling configurations of the Elastic Container Instance type to meet changing business requirements.

Usage notes

If you want to change the name of a scaling configuration in a scaling group, make sure that the new name is unique within the scaling group.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code for different SDKs.
