A template for PostgreSQL High Availability with Etcd, Consul, ZooKeeper, or Kubernetes

Project mention: Citus is not ACID but Eventually Consistent | dev.to | 2023-08-15

Citus doesn't provide fault tolerance. Each shard is a monolithic PostgreSQL. To reduce downtime on failures, you can protect each shard with a standby database. As this is a complex configuration, Patroni can help. For this lab I'll use the Citus+Patroni docker-compose-citus.yml from https://github.com/zalando/patroni.git:

Highly available elephant herd: HA PostgreSQL cluster using Docker

Project mention: Why PostgreSQL High Availability Matters and How to Achieve It | news.ycombinator.com | 2023-06-14

one of the solutions which made it pretty simple for us to run postgresql in a ha environment (mostly in k8s, but works standalone as well) is zalandos patroni: https://github.com/zalando/patroni it's really solid and worked for us for a few years already.
or for k8s their operator: https://github.com/zalando/postgres-operator (docker image: https://github.com/zalando/spilo) we've also tried other operators which were easier to get started, but they failed miserably (crunchyrolls operator is basically based on the zalando one)
