+# Katalon in Google Cloud Build
+
+This demonstrates using the
+[`Katalon`](https://github.com/katalon-studio/docker-images) tool in Google Cloud
+Build to produce Docker images in a registry, instead of using `docker build`
+and `docker push`.
+
+## Steps:
+
+1. Modify the `cloudbuild.yaml` to define the steps to build your Docker image using Katalon.
+2. Define the custom `Dockerfile` for Katalon, which installs necessary packages and defines an entry point.
+3. Use the Cloud Build trigger to automate the process of building and pushing the Katalon image to your Container Registry, tagged with both `latest` and `9.6.0`.
+
+## Trigger the build locally
+
+To trigger the build locally using `gcloud`, navigate to your project root directory and run the following command:
+
+```bash
+gcloud builds submit --config=cloudbuild.yaml .
+```
+
+This command will submit your build to Cloud Build using the cloudbuild.yaml configuration file, which includes the steps for tagging the image with both latest and 9.6.0.
