TechTrends

TechTrends is an online website used as a news sharing platform, that enables consumers to access the latest news within the cloud-native ecosystem. In addition to accessing the available articles, readers are able to create new media articles and share them.

As a platform engineer, you should package and deploy TechTrends to Kubernetes using a CI/CD pipeline.

The web application is written using the Python Flask framework. It uses SQLite, a lightweight disk-based database to store the submitted articles.
