Should I Disable Cloud Build and GCR After Building My Kubernetes App?

Deploying an application on Kubernetes Engine (GKE) for the first time can be exciting yet overwhelming. After successfully building your application using Docker, storing it in the Google Container Registry (GCR), and deploying it, you might be wondering about the next steps. Specifically, a common question arises: Should I disable Cloud Build and GCR after completing the deployment? This guide will clarify that for you so you can focus on your application's success instead of worrying about unneeded services.

Understanding the Services

Before diving into whether you should disable these services, let's break down what they are:

Cloud Build: A service that allows you to execute builds on demand. With Cloud Build, you can create Docker images or even deploy your applications without much hassle.

Google Container Registry (GCR): A service that provides a place for storing your Docker images. This is crucial for managing the lifecycle of your applications on Kubernetes as it allows you to push and pull images seamlessly.

Should You Disable Them?

Now, coming back to the core question: Should you disable Cloud Build and GCR? The straightforward answer is no, and here’s why:

1. Pay-as-You-Go Model

Google Cloud Platform operates on a pay-as-you-go model. This means that you will only incur costs based on the actual usage of these services.

Simply enabling the APIs for Cloud Build and GCR doesn't lead to significant charges. You only pay for what you use.

2. Continued Access to Docker Images

Disabling the Container Registry API could lead to complications. Your application relies on pulling images from GCR to function properly.

If you disable GCR, you may encounter issues when trying to push or pull your application’s Docker images in the future.

3. Future App Development

Keeping these services enabled will make subsequent builds and updates much smoother for your application.

If you plan to make changes, update, or rebuild your application, you won’t have to go through the hassle of re-enabling these services each time.

Conclusion: Keep Them Active

In summary, it’s advisable to keep Cloud Build and GCR enabled even after your application is up and running. Not only does this save you the trouble of re-enabling these services for future needs, but it also ensures your application runs smoothly without hiccups when accessing its required Docker images.

By following this simple approach, you can focus more on evolving and improving your application on GKE, rather than managing service states. Always remember, the flexibility and convenience of these tools are there to simplify your cloud journey!
