Are you preparing for a Google Kubernetes Engine (GKE) interview? This guide will equip you with the knowledge and insights you need to ace your interview and land your dream job. We’ve compiled a comprehensive list of GKE interview questions, covering everything from basic concepts to advanced topics.
GKE Interview Questions:
1. What is Google Kubernetes Engine (GKE)?
It is a managed, production-ready environment for putting containerized apps on Google Cloud Platform (GCP) and managing them. It makes running Kubernetes clusters easier and more automated, so you don’t have to set them up and configure them by hand.
2 What are the benefits of using GKE?
- Simplified deployment and management: GKE automates many of the tasks involved in running Kubernetes clusters, such as provisioning nodes, scaling resources, and managing security.
- High availability and scalability: GKE provides a highly available and scalable platform for running containerized applications.
- Integration with other GCP services: GKE integrates seamlessly with other GCP services, such as Cloud Storage, Cloud SQL, and Cloud Monitoring.
- Security and compliance: GKE offers a secure and compliant environment for running containerized applications.
3. How is GKE different from other Kubernetes offerings?
GKE is a managed Kubernetes service, which means that Google takes care of the underlying infrastructure and operations. This makes it a more convenient and user-friendly option for organizations that do not have the expertise or resources to manage their own Kubernetes clusters.
4. What are the different types of GKE clusters?
There are two types of GKE clusters: standard clusters and autopilot clusters. Autopilot clusters are easier to manage and scale, while standard clusters give you more freedom and control.
5. What are some of the key features of GKE?
- Automatic scaling: GKE can automatically scale your cluster up or down based on your application’s needs.
- Self-healing: GKE can automatically restart failed pods and nodes.
- Load balancing: GKE provides load balancing for your applications.
- Monitoring and logging: GKE provides integrated monitoring and logging for your applications.
6 What are some of the use cases for GKE?
GKE can be used for a variety of use cases, including:
- Deploying microservices applications
- Running stateful applications
- Batch processing
- Machine learning
7 What are some of the best practices for using GKE?
- Use the latest version of Kubernetes.
- Use a container registry to store your container images.
- Use a configuration management tool to manage your cluster configuration.
- Monitor your cluster’s health and performance.
8. What are some of the challenges of using GKE?
- Cost: GKE can be more expensive than other Kubernetes offerings.
- Complexity: GKE can be complex to set up and manage.
- Security: GKE requires careful security planning and implementation.
9. What are some of the future trends for GKE?
- Increased adoption of serverless computing.
- Greater use of artificial intelligence and machine learning.
- Continued focus on security and compliance.
10. What are some of the resources available for learning more about GKE?
- Google Cloud documentation: https://cloud.google.com/kubernetes-engine/docs/
- GKE tutorials: https://cloud.google.com/kubernetes-engine/docs/tutorials/
- GKE blog: https://cloud.google.com/blog/products/containers-kubernetes/
With this comprehensive guide, you’re well-equipped to tackle any GKE interview question that comes your way. Remember to practice your answers and be confident in your knowledge. Good luck!
What are the benefits of Kubernetes?
With the container orchestration tool Kubernetes, it becomes extremely easy to handle containers. We can respond to customer demands by deploying the applications faster and more predictably.
Here, we will list some of the benefits of Kubernetes:
- Automatic scheduling
- Automated rollback
- Horizontal scaling
- Auto-healing capabilities

1 How to write a Kubernetes scheduler?
The kube-scheduler is the default scheduler for Kubernetes. It is designed such that if you prefer, you can write your own one and use that instead.
Following is the syntax:
The scheduling life cycle:
- When a pod is made, the preferred state is written down, and the pod is saved to etcd without the node name being filled in.
- The scheduler notices the new pod with no node bound
- It finds a suitable node for that pod
- After telling the API server to connect the pod to the node, the new state is saved to etcd.
- Kubelets keep an eye on the bound pods and start the containers on that node.
