This video demo series provides comprehensive guidance on orchestrating PostgreSQL clusters with 123cluster. You’ll automate provisioning using Terraform integrated within your CI/CD workflows. Start by deploying PostgreSQL clusters and setting up standby replicas. Next, learn how to create new databases and configure HAProxy to enable efficient load balancing. Continue by exploring essential maintenance operations—starting/stopping nodes, executing controlled switchovers, and managing repmgr workflows (pause/unpause). Gain confidence in advanced operations such as exporting/restoring databases, cloning primary nodes, copying databases, and resource cleanup including dropping nodes, exports, and backups. These tutorials provide a robust foundation for production-grade, automated PostgreSQL cluster lifecycle management.
