Integration with other tools

Patroni can integrate with other tools in your stack. These examples show possible integrations. The list is not complete.

Barman

Patroni provides patroni_barman. This application communicates with pg-backup-api to run Barman operations remotely.

The application has two subcommands: recover and config-switch.

patroni_barman recover

Use the recover subcommand as a custom bootstrap method or replica creation method. See replica_imaging_and_bootstrap for details.

patroni_barman config-switch

Use the config-switch subcommand as an on_role_change callback in Patroni. For example, you may stream WALs from the primary to your Barman host. After a failover, you may want to stream from the new primary. Use patroni_barman config-switch as the on_role_change callback for this change.

This example applies a configuration model when the Patroni node becomes primary:

postgresql:
    callbacks:
        on_role_change: >
            patroni_barman
                --api-url YOUR_API_URL
                config-switch
                --barman-server YOUR_BARMAN_SERVER_NAME
                --barman-model YOUR_BARMAN_MODEL_NAME
                --switch-when promoted
