Services → Scale
AI-generatedOverview
This node interacts with Kubernetes to perform various operations on Kubernetes resources. Specifically, the 'Scale' operation allows users to adjust the number of replicas for a specified Kubernetes resource, such as a deployment or service, within a given namespace. This is useful for scaling applications up or down based on demand or resource availability.
Use Case Examples
- Scaling a deployment named 'my-app' in the 'default' namespace to 3 replicas to handle increased traffic.
- Reducing the number of replicas of a service to 1 during low usage periods to save resources.
Properties
| Name | Meaning |
|---|---|
| Namespace | The Kubernetes namespace where the target resource resides. Defaults to 'default' if not specified. |
| Resource Name | The name of the Kubernetes resource to scale. |
| Replicas | The desired number of replicas to scale the resource to. |
Output
JSON
json- The JSON response from the Kubernetes API after scaling the resource, typically containing the updated resource details.
Dependencies
- Requires Kubernetes API credentials to authenticate and interact with the Kubernetes cluster.
Troubleshooting
- Ensure that the 'Resource Name' is provided; otherwise, the node will throw an error indicating the resource name is required for the scale operation.
- Verify that the Kubernetes credentials are correctly configured and have sufficient permissions to scale the specified resource.
- Check that the 'Replicas' value is a valid number; invalid values may cause the scaling operation to fail.
