cce-hpa-controller
cce-hpa-controller is a CCE-developed add-on, which can be used to flexibly scale in or out Deployments based on metrics such as CPU usage and memory usage.
After installing this add-on, you can create a CustomedHPA policy on the Workload Scaling tab page of the Auto Scaling page. For details, see Creating a CustomedHPA Policy for Workload Auto Scaling.
Main Functions
- Scaling can be performed based on the percentage of the current number of pods.
- The minimum scaling step can be set.
- Different scaling operations can be performed based on the actual metric values.
Notes and Constraints
- This add-on can be installed only in CCE clusters of v1.15 or later.
- If the cce-hpa-controller version is earlier than 1.2.11, the prometheus add-on must be installed. If the cce-hpa-controller version is 1.2.11 or later, the add-ons that can provide metrics API, such as metrics-server and prometheus, must be installed. If Prometheus is used, you need to register Prometheus as the service that provides metrics API. For details, see Providing Resource Metrics.
