Master Microservices with Spring Boot and Spring Cloud - Step 20 – Deploying Microservices Using Kubernetes YAML Configu

The video tutorial covers deploying applications using Kubernetes and YAML files. It begins by addressing warnings related to deployment commands and demonstrates how to delete existing deployments using labels. The tutorial then guides viewers through applying new deployments with YAML files, monitoring the status of deployments and services, and testing deployments using the curl command. Finally, it explains how to modify deployments by changing configurations in the YAML file, such as scaling and version updates.

• To check the number of nodes

How can you change the number of instances in a deployment using YAML?

• By deleting and recreating the deployment

• By restarting the Kubernetes cluster

• By using the kubectl scale command

• By editing the replica count in the YAML file

What is the advantage of using a deployment YAML file for version updates?
