InstanceCount
The number of EC2 instances in your Rack cluster. This parameter is only used for clusters with HighAvailability set to true.
| Default value | 3 |
| Minimum value | 3 |
Use Cases
- Increasing instance count to handle higher application workloads or run more containers
- Setting to a higher value when deploying multiple services that require dedicated instance capacity
- Adjusting alongside Autoscale to set a minimum floor for the cluster size
Additional Information
When HighAvailability is set to false, this parameter is not used. Instead, the NoHaInstanceCount parameter controls the cluster size, which has a minimum value of 1.
If Autoscale is enabled, the cluster may scale beyond this value based on workload demand. The InstanceCount effectively serves as the baseline number of instances.
