Patroni is a template for PostgreSQL high availability.

Patroni is a template for you to create your own customized, high-availability solution using Python and - for maximum accessibility - a distributed configuration store like ZooKeeper, etcd, Consul or Kubernetes. Database engineers, DBAs, DevOps engineers, and SREs who are looking to quickly deploy HA PostgreSQL in the datacenter-or anywhere else-will hopefully find it useful.

We call Patroni a 'template' because it is far from being a one-size-fits-all or plug-and-play replication system. It will have its own caveats. Use wisely.

Note to Kubernetes users: Patroni can run natively on top of Kubernetes. Take a look at the Kubernetes chapter of the Patroni documentation.
