repmgr PostgreSQL Replication Manager Primary on Ubuntu 24.04 LTS
Azure
Databases
A PostgreSQL primary with repmgr preconfigured, registered and monitored, ready to add standby nodes.
Overview
repmgr is the long established open source toolset for managing PostgreSQL streaming replication and automatic failover. This appliance is a fully configured PostgreSQL primary node with repmgr installed, the primary registered, and the repmgrd monitoring daemon running. It gives teams a proven starting point for building a highly available PostgreSQL cluster: clone standby nodes against it, register them, and repmgr manages promotion and failover.
Why the cloudimg image
cloudimg ships PostgreSQL and repmgr preconfigured on a hardened, fully patched base with the primary already registered as node 1 and repmgrd enabled. Unique passwords for the database superuser and the repmgr role are generated on first boot with no default login, every connection is encrypted with a per instance TLS certificate, standby joins are restricted to authenticated TLS connections, and 24/7 support is included.
Common uses
- Highly available PostgreSQL clusters
- Streaming replication and automatic failover
- Disaster recovery standby nodes
