    Fine-tune GKE services with Gemini assistance

    This page describes how you can fine-tune your Google Kubernetes Engine (GKE) deployments to optimize performance and reliability by using Gemini Cloud Assist , an AI-powered collaborator for Google Cloud. Gemini assistance can include recommendations, code generation, and troubleshooting.

    Among many other benefits, Gemini Cloud Assist can help you achieve the following:

    • Reduce costs: identify idle resources, rightsize your deployments, and optimize autoscaling configurations to minimize unnecessary spending.
    • Improve reliability and stability: proactively identify potential issues, like version skew or missing Pod Disruption Budgets, to prevent downtime and ensure application resilience.
    • Optimize AI/ML Workloads: get help with deploying, managing, and optimizing AI/ML workloads on GKE.
    • Simplify troubleshooting: quickly analyze logs and pinpoint the root cause of errors, saving time and effort.

    This page is for existing GKE users, and Operators and Developers who provision and configure cloud resources and deploy apps and services. To learn more about common roles and example tasks referenced in Google Cloud content, see Common GKE user roles and tasks .

    Costs

    • Gemini: While in Preview, there is no cost for using Gemini Cloud Assist.

    • GKE: There are no additional costs for using Gemini Cloud Assist in GKE.

    Before you begin

    To begin using Gemini with GKE, complete the following prerequisites.

    This guide assumes that you have a GKE cluster and, preferably some deployments running.

    Ask Gemini Cloud Assist

    You can invoke Gemini Cloud Assist from the Google Cloud console. Gemini Cloud Assist lets you use natural language prompts to get help with tasks quickly and efficiently.

    To open Cloud Assistfrom a GKE page, follow these steps:

    1. In the Google Cloud console, on the project selector page, select a Google Cloud project where you enabled Gemini Cloud Assist .

      Go to project selector

    2. In the Google Cloud console, go to a specific page on the Kubernetes Engineconsole.

      For example, go to the Kubernetes Engine Overviewpage.

      Go to Kubernetes Engine Overview

      If you have a question about a specific resource, navigate first to the relevant page. For example, on the Clusters page, Gemini Cloud Assist can advise you about managing your clusters, monitoring your cluster health, and troubleshooting cluster issues. Using Gemini on a specific Google Cloud console page helps provide context for your questions. Gemini can then use this context, along with the overall project you're in, to generate more tailored and accurate assistance.

    3. To open the Gemini Cloud Assist pane, click the spark Open or close Gemini AI chatin the toolbar.

    4. If prompted, and you agree to the terms, click Accept.

    5. Enter a prompt in the Gemini pane. See an example workflow of using Gemini to troubleshoot in the following section.

    For more information about using Gemini in the Google Cloud console, see Use Gemini Cloud Assist .

    Example of using Gemini to troubleshoot

    Gemini can help you troubleshoot issues in your GKE services.

    1. Go to the Workloadspage in the Google Cloud console.

      Go to Workloads

    2. Select the workload you want to troubleshoot.

    3. Click the Logstab.

    4. Click the spark Open or close Gemini AI chatin the toolbar.

    5. Enter a prompt to describe the issue you are experiencing. For example, "My accounts-db database application is experiencing high latency". Gemini might ask for more context, such as the type of database, the scope of impact, such as the operations and users affected by the latency.

    6. Gemini can then provide guidance to analyze the logs yourself, and provide troubleshooting suggestions.

    7. Review and follow the suggestions to resolve the issue.

    Example prompts for Gemini Cloud Assist

    This section shows some real-world use cases and suggests the prompts that you can try asking Gemini. The actual responses you receive might be generic, or they might be personalized and actionable based on the unique state of your Google Cloud environment. The responses could include Google Cloud console links for reviewing and managing your Cloud resources, and links to the relevant documentation for further information.

    Reduce costs

    The following table describes the prompts you can use to help reduce costs.

    Prompt
    Type of response
    "How can I save costs on my GKE clusters without sacrificing performance?"
    • Recommendations that identify and suggest the removal of underutilized resources, such as idle clusters.
    • Advice about enabling or adjusting autoscaling mechanisms.
    • Suggestions that highlight potential savings through configuration reviews, such as logging retention policies.
    "I'm looking to upgrade my my-docker-cluster GKE cluster. Any recommendations?"
    Suggestions to implement specific Kubernetes configurations and best practices, for example:
    • Defining resource requests and limits for Pods to help ensure predictable resource allocation.
    • Using dedicated namespaces to isolate workloads.
    • Implementing Pod Disruption Budgets to help ensure that a minimum number of Pod replicas are available during voluntary disruptions, like node maintenance or upgrades.
    • Scheduling maintenance windows to manage planned disruptions and minimize unexpected downtime.
    • Enrolling clusters in release channels to manage GKE version upgrades.
    "I have a large traffic spike coming in a couple of weeks on the my-docker-cluster cluster. Any recommendations?"
    • Strategies to scale the number of application Pods by using the horizontal Pod autoscaler.
    • Strategies to increase the resources (CPU, memory) per Pod by using the vertical Pod autoscaler.
    "Which of my GKE workloads don't have HPA enabled?"
    The list of workloads that don't have the horizontal Pod autoscaler enabled.
