Udemy – Postgres Cluster: Master Patroni-Managed Clusters 2025-7

Postgres Cluster Course: Master Patroni-Managed Clusters. This hands-on course teaches you how to set up a high availability (HA) cluster for your PostgreSQL database using Patroni in a modern Linux environment. Participants will learn how to build a robust and operational cluster that ensures service continuity even in the event of a failure. The architecture is implemented using PostgreSQL as the database, Patroni for automatic failover and replication, ETCD as a distributed repository to maintain consensus, HAProxy for intelligent routing of connections to the master node, and Keepalived for creating a virtual IP address for uninterrupted availability. Key topics covered in the course include understanding the concept of Quorum and its function in a cluster, avoiding issues such as split-brain, safely performing manual and automatic failover between nodes, continuously monitoring cluster health, and simulating real-world failure and recovery scenarios. Finally, best practices for configuration in production environments are presented to ensure data stability and integrity.
