Create google.yml

[ahboyvanz]

This workflow will build a docker container, publish it to Google Container Registry, and deploy it to GKE.

To configure this workflow:

1. Ensure that your repository contains the necessary configuration for your Google Kubernetes Engine cluster, including deployment.yml, kustomization.yml, service.yml, etc.

2. Set up secrets in your workspace: GKE_PROJECT with the name of the project, GKE_EMAIL with the service account email, GKE_KEY with the service account key.

3. Change the values for the GKE_ZONE, GKE_CLUSTER and IMAGE environment variables (below).

name: Build and Deploy to GKE

push:
