To authenticate with Google Kubernetes Engine (GKE) while using Cloud Build, what should you do?

To authenticate with Google Kubernetes Engine (GKE) while using Cloud Build, assigning the Container Developer role to the Cloud Build service account is the correct approach. This role provides the necessary permissions for the service account to manage Kubernetes resources, facilitating seamless operations such as deploying applications, updating configurations, and scaling workloads.

The Container Developer role is specifically tailored for tasks that involve interaction with Kubernetes clusters, making it ideal for Cloud Build's operational needs. By enabling this role, you ensure that the Cloud Build service account has the required access without granting unnecessary permissions, thereby adhering to the principle of least privilege.

In contrast, creating a separate step in Cloud Build to authenticate with GKE using kubectl may seem like a functional option but doesn't address the requirement of granting permissions to interact with the cluster itself. The process relies on having the correct roles and permissions set beforehand.

Assigning the Kubernetes Admin role might provide broad access, but it's not optimal for all scenarios, especially in production environments where tighter security is essential. Such a role could expose the cluster to risks by allowing actions that might not be necessary for the specific automation tasks that Cloud Build is intended to perform.

Specifying the Container Developer role in the cloudbuild.yaml file is also incorrect because while configurations in the YAML
