What action should you take to enable specific application version deployment when pushing an image?

Using Cloud Build to include the release version tag in the application image is the optimal approach because it integrates the build and deployment processes effectively. When you tag your Docker images with specific version identifiers during the build process, it ensures that each version of your application is uniquely identifiable. This tagging facilitates the deployment of a specific version, allowing for controlled rollouts and the ability to quickly revert to previous versions if necessary.

In the context of DevOps practices, managing versions accurately is crucial for maintaining stability and traceability in your applications. By incorporating version tagging directly into your build pipeline, you align the deployment process with best practices such as Continuous Integration and Continuous Deployment (CI/CD), where changes can be easily tracked, promoted, and rolled back.

Other choices may touch on aspects of tagging and referencing images, but they either lack the integration provided by effectively using Cloud Build for versioning or do not provide a straightforward approach to managing application versions in a deployment context. Therefore, utilizing Cloud Build for this purpose is the most efficient way to ensure specific application version deployments when pushing an image.
