W OP workflow

[jackiebrewster307]

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 Base64 encoded JSON service account key (https://github.com/GoogleCloudPlatform/github-actions/tree/docs/service-account-key/setup-gcloud#inputs).

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