Assurez-vous de créer une politique `DenyAll` avec `podSelector: {}` avant toute règle d’autorisation : Kubernetes évalue toutes les politiques en union, donc l’absence de refus explicite laisse tout passer. Pour DNS, autorisez l’egress vers `kube-dns` (port 53/UDP). Utilisez des sélecteurs de namespace et de pod précis (via `matchLabels`) pour éviter les fuites inter-namespaces. Testez avec `kubectl run --image=alpine -it` en vérifiant les connexions bloquées.

GitHub Copilot Prompt to Generate a Database Schema
GitHub Copilot radically transforms how developers design their databases. Instead of starting from a blank sheet and manually writing each CREATE TABLE statement, you can now describe your business domain in natural language and get a complete schema in seconds. The tool excels particularly in generating relational schemas with appropriate primary keys, foreign keys, indexes, and constraints. Whether you work with PostgreSQL, MySQL, SQLite, or SQL Server, Copilot adapts the syntax and data types to the targeted SQL dialect. This approach significantly accelerates the modeling phase, reduces syntax errors, and allows you to focus on business logic rather than SQL mechanics. A well-crafted prompt is key: by specifying the application context, entity relationships, and business constraints, you get a production-ready schema that follows best practices for normalization and performance.
