Master Microservices with Spring Boot and Spring Cloud - Step 17 – Creating Declarative Configuration Kubernetes YAML fo

The video tutorial explains how to deploy applications using Kubernetes, focusing on creating and modifying YAML configuration files. It demonstrates the process of adjusting deployment settings, such as replicas, and applying these changes. The tutorial also highlights Kubernetes' ability to provide load balancing and service discovery, emphasizing its declarative approach to managing application states.

What is the primary benefit of using YAML files in Kubernetes?

• They allow for imperative configuration of services.

• They enable declarative configuration of desired states.

• They are used for scripting Kubernetes commands.

• They provide a graphical interface for Kubernetes.

Which command is used to get deployment information in YAML format?

• kubectl get service

• kubectl describe deployment

• kubectl get deployment -o yaml

• kubectl apply -f deployment.yaml

Why is it beneficial to combine deployment and service configurations into a single YAML file?

• It enables automatic updates.

• It simplifies the configuration process.

• It reduces the number of files to manage.

• It allows for faster deployment.

What change is made to the deployment YAML to increase the number of replicas?

• Update the image version.

• Change the deployment name.

• Modify the 'replicas' field.

• Add a new service entry.

How does Kubernetes ensure the desired state is achieved?

• By comparing current and desired configurations.

• By manually adjusting configurations.

• By using a trial-and-error method.

• By relying on user input for changes.

What feature of Kubernetes allows for automatic load balancing?

• Service discovery

• Environment variables

• Declarative configuration

• Load balancing

What command is used to apply changes from a YAML file in Kubernetes?

• kubectl deploy -f

• kubectl apply -f

• kubectl execute -f

• kubectl update -f
