Configuring Automation for a cluster

Cluster-level automation configuration allows the definition of global settings that apply to all workloads within the cluster.

You can effortlessly exclude specific namespaces and workloads from Automation. Learn more here.

Including a cluster to the Automation

Configuration with additional parameters

The following cluster-level automation configuration example represents global automation settings that apply to all workloads with the type Deployment within the cluster. Additionally, there is a specified frequency of the automation actions and maintenance window, which gives you control over the automation and minimizes the impact of changes on business operations.

Uncover the full range of customization options, how to implement them and tailor Automation for your application's needs here.

Create a YAML file with the cluster-level automation configuration using the following template:

apiVersion: perfectscale.io/v1
kind: ClusterAutomationConfig
metadata:
  name: cluster-automation-config
spec:
  automation:
    operational:

Apply the created configuration by running the following command (where cluster-automation-config.yaml - the name of your file created in the previous step):

kubectl apply -f cluster-automation-config.yaml
