WalkthroughThe pull request introduces a comprehensive set of configuration files for a Continuous Integration and Continuous Deployment (CI/CD) pipeline targeting a two-tier Flask application. The changes include multiple YAML pipeline configurations for Azure DevOps, a MySQL Dockerfile, and a minor update to the application code. The new pipeline setup focuses on automating the build, image creation, and deployment processes using Docker Compose, with specific configurations for building, artifact management, and service deployment.

Critical: Avoid using root user for MySQL
Using the root user for database operations poses a significant security risk. Create a dedicated database user with limited privileges instead.

Security: Move credentials to environment variables
Hardcoding credentials in Dockerfile is a security risk. Use build arguments or environment variables instead.

Implement proper version tagging strategy
Using only 'latest' tag is risky for production deployments. Consider adding git commit SHA or build number.

Optimize artifact publishing
Publishing the entire source directory $(Build.SourcesDirectory) is inefficient. Consider publishing only the necessary Docker-related files.
