Understanding Dry Run mode

The ClusterDeployment process includes a "dry run" mode, which enables you to validate your configuration without actually provisioning resources. By default, .spec.dryRun is set to false, but enabling it can help identify potential issues early.

Note that if no configuration (.spec.config) is provided, default values from the selected template will populate the object, and .spec.dryRun will automatically be enabled.

Example: Dry Run with default configuration:

apiVersion: k0rdent.mirantis.com/v1alpha1
kind: ClusterDeployment
metadata:
  name: my-cluster-deployment
  namespace: kcm-system
spec:
  template: aws-standalone-cp-0-0-3
  credential: aws-credential
  dryRun: true

After validation (this is, you see TemplateReady as a condition in .status.conditions), remove or disable .spec.dryRun to proceed with deployment.

Example: Validated ClusterDeployment object:

apiVersion: k0rdent.mirantis.com/v1alpha1
kind: ClusterDeployment
metadata:
  name: my-cluster-deployment
  namespace: kcm-system
spec:
  template: aws-standalone-cp-0-0-3
  credential: aws-credential
  config:
    clusterLabels: {}
    region: us-east-2
    publicIP: true
    controlPlaneNumber: 1
    workersNumber: 1
    controlPlane:
      instanceType: t3.small
    worker:
      instanceType: t3.small
  status:
    conditions:
    - type: TemplateReady
      status: "True"
      reason: Succeeded
      message: Template is valid
    - type: Ready
      status: "True"
      reason: Succeeded
      message: ClusterDeployment is ready
