Question

What did you do?

I'm encountering an issue with the reconciliation process of my Operator SDK project. Here's a breakdown of the situation:

I have an Operator SDK project with the following ComponentSpec struct:

type ComponentSpec struct {
    Size  int32  `json:"size"`
    Chart string `json:"chart"`
}

And I have a YAML manifest for a custom resource of kind Component:

apiVersion: ezto.ezto.io/v1alpha1
kind: Component
metadata:
  labels:
    app.kubernetes.io/name: component
    app.kubernetes.io/instance: component-sample
    app.kubernetes.io/managed-by: kustomize
  name: component-sample
spec:
  size: 1
  chart: test

At recouncile function im just logging the values

func (r *ComponentReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error) {
  _ = log.FromContext(ctx)
  var componentLog = ctrl.Log.WithName("component")
  componentLog.Info("starting reconciling", "name", eztov1alpha1.Component{})
  return ctrl.Result{}, nil
}

What did you expect to see?

I expected the reconciliation process to populate the Chart field of the ComponentSpec struct with the value "test" from the provided YAML manifest during reconciliation.

{"name": {"metadata":{"creationTimestamp":null},"spec":{"size":0,"chart":"test"}}}

What did you see instead? Under which circumstances?

However, during reconciliation, the Chart value remains empty. Here's the log indicating the issue:

{"name": {"metadata":{"creationTimestamp":null},"spec":{"size":0,"chart":""}}}

Environment

Operator type: Go

Kubernetes cluster type: Vanilla

$ operator-sdk version

operator-sdk version: "v1.34.1"
commit: "edaed1e5057db0349568e0b02df3743051b54e68"
kubernetes version: "v1.28.0"
go version: "go1.21.7"
GOOS: "darwin"
GOARCH: "amd64"

$ go version

go version go1.21.7 darwin/amd64

$ kubectl version

Client Version: v1.29.1
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.29.1

Additional context

This issue persists despite the provided YAML manifest containing the correct value for the chart field.

Any assistance in resolving this issue would be greatly appreciated. Thank you!

https://sdk.operatorframework.io/docs/building-operators/golang/tutorial/#reconcile-loop
recouncil loop has to be implemented before using the struct

ezto := &eztov1alpha1.Component{}
err := r.Get(ctx, req.NamespacedName, ezto)
