Patroni

Environment Configuration Settings

It is possible to override some of the configuration parameters defined in the Patroni configuration file using the system environment variables. This document lists all environment variables handled by Patroni. The values set via those variables always take precedence over the ones set in the Patroni configuration file.

Global/Universal

Log

Citus

Enables integration Patroni with Citus. If configured, Patroni will take care of registering Citus worker nodes on the coordinator. You can find more information about Citus support here.

Consul

Etcd

Etcdv3

Environment names for Etcdv3 are similar as for Etcd, you just need to use ETCD3 instead of ETCD in the variable name. Example: PATRONI_ETCD3_HOST, PATRONI_ETCD3_CACERT, and so on.

Warning

Keys created with protocol version 2 are not visible with protocol version 3 and the other way around, therefore it is not possible to switch from Etcd to Etcdv3 just by updating Patroni configuration.
