This video provides a hands-on tutorial on deploying applications using GitLab CI and Kubernetes. It covers key Kubernetes resources such as deployments, services, persistent volume claims, and Ingress. The tutorial explains how to configure GitLab CI to deploy applications to Kubernetes, focusing on the use of Docker image tags and environment variables. It also details the setup of services and deployments for both a Node.js web application and a Postgres database, including persistent storage solutions. Finally, it discusses traffic routing through Ingress and the use of wildcard DNS for external access.

What is the significance of the persistent volume claim for the Postgres database?

Describe the function of the Ingress in the Kubernetes architecture.

How does the GitLab CI process integrate with Kubernetes for application deployment?
