PostgreSQL HA with Patroni, etcd and HAProxy

Online event

PostgreSQL HA with Patroni, etcd and HAProxy



Silicon Valley In-Person event CFP:


Community Chat:


Presented by: Abbas Butt
This presentation will provide step by step details on how to deploy a highly available PostgreSQL cluster using Patroni, etcd and HAProxy. Patroni is a python based solution to provide HA and automatic failover in a PostgreSQL cluster. Patroni depends on etcd and HAProxy to provide all the features. This presentation will provide steps to deploy and test etcd and HAProxy independently. Once all the dependent modules are deployed and tested to work, the presentation will then provide steps to do and test a manual failover. The presentation will use four CentOS 7 virtual machines. On each VM we will deploy PostgreSQL 12.6, etcd version[masked] and Patroni version 2.0.2. On one of the VMs we will have HAProxy version[masked]
