Force apply with kubectl apply despite no changes

Question

kubectl apply does not apply since the file does not change, below is the content mci.yaml (just for reference, not essential).

apiVersion: networking.gke.io/v1
kind: MultiClusterIngress
metadata:
  name: terraback-ingress
  namespace: terraback
spec:
  template:
    spec:
      backend:
        serviceName: terraback-mcs
        servicePort: 4000

Below is the command and response

(base) PS D:\terraform_small\terra-back> kubectl apply -f mci.yaml
multiclusteringress.networking.gke.io/terraback-ingress unchanged

But I need it to force apply, since terraback-mcs has changed, but is there a way to force apply despite no changes with kubectl apply ?

Answer 1

In this case, you do not need to update the Ingress spec since neither the service name nor port has changed. But if you really to force a replacement, you can try: kubectl replace -f mci.yaml --force

Answer 2

Below is the command and response

(base) PS D:\terraform_small\terra-back> kubectl apply -f mci.yaml

-f doesn't mean force - it means file, you need --force , so:

kubectl apply -f mci.yaml --force
