Implement DevOps Workflows in Google Cloud
Creating a GKE cluster based on a set of configurations provided. Creating a Google Source Repository to host your Go application code. Creating Cloud Build Triggers that deploy a production and development application. Pushing updates to the app and creating new builds. Rolling back the production application to a previous version.
Overall, you are creating a simple CI/CD pipeline using Cloud Source Repositories, Artifact Registry, and Cloud Build.
Welcome to Cloud Shell! Type "help" to get started.
Your Cloud Platform project in this session is set to qwiklabs-gcp-03-3b729f45e4ec.
Use “gcloud config set project [PROJECT_ID]” to change to a different project.
