Master Microservices with Spring Boot and Spring Cloud - Step 25 – Exploring Microservices Deployments with Kubernetes

The video tutorial covers the functional features of microservices, focusing on centralized configuration, logging, and service discovery. It then shifts to application deployments, discussing how to ensure smooth deployments with minimal downtime using Kubernetes. The tutorial explores checking rollout history, handling deployment errors, and rolling back to previous versions. It also demonstrates deploying new versions and addresses downtime issues during deployment transitions.

What is the primary focus when discussing deployments in microservices?

• Improving the speed of deployments

• Ensuring smooth and downtime-free deployments

• Increasing the number of deployments

• Reducing the size of deployments

Which command is used to check the rollout history of a deployment in Kubernetes?

• kubectl history list

• kubectl deployment history

• kubectl rollout history

• kubectl get history

What happens if a new deployment in Kubernetes has an invalid image name?

• The system crashes

• The old deployment is deleted

• The new deployment is automatically corrected

• The new deployment is ignored and the old one continues running

How can you revert to a previous deployment version in Kubernetes?

• By restarting the Kubernetes cluster

• By using the kubectl rollout undo command

• By using the kubectl rollback command

• By deleting the current deployment

What does Kubernetes do if a new deployment fails?

• It shuts down the service

• It rolls back to the previous version

• It sends an alert to the administrator

• It automatically retries the deployment

What is a common issue when switching from one deployment to another?

• Increased resource usage

• Downtime during the switch

• Loss of data

• Security vulnerabilities

What is the next step after identifying downtime issues during deployments?

• Ignore the downtime

• Explore solutions to avoid downtime

• Increase the deployment frequency

• Reduce the number of services
