Containerization of Dotnet Application

Project Goals

The project aimed to migrate an ASP.net application from a single multi-tenant Windows server to a more scalable and isolated Kubernetes environment, with the primary objective of improving system manageability and tenant separation. Project Deliverables

Project Deliverables

• Upgrading the application to .NET 6
• Containerizing the frontend and backend applications
• Implementing an automated deployment pipeline using Azure DevOps
• Configuring image storage and deployment in AWS ECR and Kubernetes

Challenges Encountered

Our team faced several technical challenges, including:

• Ensuring application compatibility with Linux containers
• Refactoring environment-specific configuration - Previously there was one build per environment, but that makes it impossible to test the exact artifact we are deploying.
• Addressing file system and logging dependencies that prevented fully immutable containers

Project Outcomes

We were fully successfull and migrated the application to Kubernetes, creating a more flexible and scalable infrastructure. The containerization process required minimal code changes and resulted in a deployable system that could be consistently used across different environments.

Key Takeaways

The project demonstrated the importance of:

• Flexible application design that supports environment-agnostic deployments
• Continuous collaboration between development and DevOps teams leading to greatly improved product quality and realease processes
