<p>I am working on setting up CI CD pipeline for Spring boot application on GKE. The CI build step worked correctly but the delivery build step is failing due to 'error: no objects passed to apply' error. I could see below logs in the cloud build</p>

<pre><code>Starting Step #0 - "Deploy"
Step #0 - "Deploy": Already have image (with digest): gcr.io/cloud-builders/kubectl
Step #0 - "Deploy": Running: gcloud container clusters get-credentials --project="location-finder-kubernetes" --zone="us-central1-b" "location-finder"
Step #0 - "Deploy": Fetching cluster endpoint and auth data.
Step #0 - "Deploy": kubeconfig entry generated for location-finder.
Step #0 - "Deploy": Running: kubectl apply -f kubernetes.yaml
Step #0 - "Deploy": error: no objects passed to apply
Finished Step #0 - "Deploy"
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/kubectl" failed: exit status 1
</code></pre>

<p>where location-finder is the name of the cluster.</p>

<p>To set up this pipeline, I followed all the guidelines mentioned at <a href="https://cloud.google.com/kubernetes-engine/docs/tutorials/gitops-cloud-build" rel="noreferrer">https://cloud.google.com/kubernetes-engine/docs/tutorials/gitops-cloud-build</a></p>

<p>The cloudbuild.yaml content for this failing step is</p>

<pre><code>steps:
- name: 'gcr.io/cloud-builders/kubectl'
  id: Deploy
  args:
  - 'apply'
  - '-f'
  - 'kubernetes.yaml'
  env:
  - 'CLOUDSDK_COMPUTE_ZONE=us-central1-b'
  - 'CLOUDSDK_CONTAINER_CLUSTER=location-finder'
</code></pre>

<p>Kubectl version:</p>

<pre><code>kubectl version

</code></pre>

<p>Am I missing any configuration?</p>

<p>To test, I ran the same <code>kubectl apply -f kubernetes.yaml</code>, but passed an empty yaml file and got the same error as you. Is there anyting acutally in your yaml file? </p>
