Pipeline: Detect & correct GKE clusters without vertical pod autoscaling

Detect & correct Kubernetes clusters with Vertical Pod Autoscaling disabled

Overview

Vertical Pod Autoscaling (VPA) is a feature of Kubernetes that allows the Kubernetes control plane to adjust the resource requests of a pod based on its usage. This can help to ensure that pods have the resources they need to run efficiently.

This pipeline detects Kubernetes clusters that have Vertical Pod Autoscaling disabled and then either sends a notification or attempts to perform a predefined corrective action.

Getting Started

This control will work out-of-the-box with some sensible defaults (configurable via variables).

You should be able to simply run the following command in your terminal:

flowpipe pipeline run detect_and_correct_kubernetes_clusters_vertical_pod_autoscaling_disabled

By default, Flowpipe runs in wizard mode and prompts directly in the terminal for a decision on the action(s) to take for each detected resource.

However, you can run Flowpipe in server mode with external integrations, allowing it to prompt for input via http, slack, teams, etc.

Alternatively, you can choose to configure and run in other modes:

Notify: Provides detections without taking any corrective action.
Automatic: Performs corrective actions automatically without user intervention.

Run the pipeline

To run this pipeline from your terminal:

flowpipe pipeline run gcp_thrifty.pipeline.detect_and_correct_kubernetes_clusters_vertical_pod_autoscaling_disabled

Use this pipeline

To call this pipeline from your pipeline, use a step:

step "pipeline" "step_name" {
  pipeline = gcp_thrifty.pipeline.detect_and_correct_kubernetes_clusters_vertical_pod_autoscaling_disabled  
}
