Managing Certificate Rotation in PgBouncer for PostgreSQL on Azure

When managing cloud database connections, security certificates eventually expire. Knowing how to rotate these certificates without causing downtime is a critical skill for keeping your PostgreSQL databases secure and accessible. This course guides you through the entire lifecycle of certificate management when running PgBouncer inside Docker containers on Azure. You will transition from understanding basic security concepts to confidently executing certificate updates. By learning the mechanics of how PgBouncer handles SSL/TLS handshakes, you will ensure your applications maintain uninterrupted, encrypted connections to Azure Database for PostgreSQL. What you'll learn: - Understand the fundamentals of SSL/TLS certificates and why rotation is necessary - Configure PgBouncer within a Docker container to connect securely to PostgreSQL - Monitor certificate expiration dates and plan proactive rotation schedules - Update containerized certificates manually and automate the process using modern DevOps workflows - Verify connection security and troubleshoot common handshake errors after a rotation - Implement container health checks to ensure PgBouncer always uses the active certificate This course begins with foundational concepts of connection pooling and database encryption. You will then progress through step-by-step written guides that demonstrate how to update certificates inside Docker containers, verify the configuration, and maintain high availability. This course is designed for beginner systems administrators, database operators, and cloud engineers who are new to database security and containerized connection pooling. No advanced DevOps experience is required. Start mastering database connection security and ensure your cloud applications remain secure and connected.
