So i have this project that i already deployed in GKE and i am trying to make the CI/CD from github action. So i added the workflow file which contains
name: Build and Deploy to GKE
on:
push:
branches:
- main
env:
PROJECT_ID: ${{ secrets.GKE_PROJECT }}
GKE_CLUSTER: ${{ secrets.GKE_CLUSTER }} # Add your cluster name here.
GKE_ZONE: ${{ secrets.GKE_ZONE }} # Add your cluster zone here.
DEPLOYMENT_NAME: ems-app # Add your deployment name here.
IMAGE: ciputra-ems-backend
jobs:
setup-build-publish-deploy:
name: Setup, Build, Publish, and Deploy
runs-on: ubuntu-latest
environment: production
steps:
- name: Checkout
uses: actions/checkout@v2
# Setup gcloud CLI

with:

project_id: ${{ secrets.GKE_PROJECT }}
# Configure Docker to use the gcloud command-line tool as a credential
# helper for authentication
- run: |-

# Get the GKE credentials so we can deploy to the cluster
- uses: google-github-actions/get-gke-credentials@fb08709ba27618c31c09e014e1d8364b02e5042e

# Build the Docker image

# Push the Docker image to Google Container Registry

docker push "gcr.io/$PROJECT_ID/$IMAGE:$GITHUB_SHA"
# Set up kustomize
- name: Set up Kustomize
run: |-
curl -sfLo kustomize https://github.com/kubernetes-sigs/kustomize/releases/download/v3.1.0/kustomize_3.1.0_linux_amd64
chmod u+x ./kustomize
# Deploy the Docker image to the GKE cluster
- name: Deploy
run: |-
./kustomize edit set image LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE:TAG=$GAR_LOCATION-docker.pkg.dev/$PROJECT_ID/$REPOSITORY/$IMAGE:$GITHUB_SHA
./kustomize build . | kubectl apply -k ./
kubectl rollout status deployment/$DEPLOYMENT_NAME
kubectl get services -o wide
but when the workflow gets to the deploy part, it shows an error
The Service "ems-app-service" is invalid: metadata.resourceVersion: Invalid value: "": must be specified for an update
Now i have searched that this is actually not true because the resourceVersion is supposed to change for every update so i just removed it
Here is my kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- service.yaml
- deployment.yaml
my deployment.yaml
apiVersion: apps/v1

In case anyone still having this problem, I may not be able to help if you still want to use GKE, But you can try the answer from @ChandraKiranPasumarti. For me personally, my senior only require me to containerize our app so I use Google Cloud Run Instead for easier deployments and CI/CD. You can use this file to use CI/CD in Cloud Run
https://github.com/google-github-actions/setup-gcloud/blob/main/example-workflows/cloud-run/cloud-run.yml
Just make sure you've added secret from service account json in you repo, then select the credentials json for authentication in your yml file
