You need a Jenkins installation to build and deploy source code and want to automate installation quickly. What should you do?

Deploying Jenkins from the Google Cloud Marketplace is the quickest and most automated way to set up Jenkins. Marketplace solutions are pre-configured and optimized, allowing for one-click deployment with minimal manual intervention. Creating a Compute Engine instance and running the Jenkins executable would involve manual installation steps, including OS setup, Java installation, and Jenkins configuration, which is not the quickest option. Creating a GKE cluster and deploying the official Jenkins container image offers scalability and resilience but requires setting up a GKE cluster first, which is more complex and time-consuming than a Marketplace deployment for a quick setup. Creating an instance template and a managed instance group is suitable for scalable, identical deployments but still requires manual configuration of the template, making it less immediate than a Marketplace solution for a single, quick installation.
