Configuration

patroni

Config directory

This image uses a config directory (/config/patroni) instead of patroni.yaml. All YAML files in this directory are loaded one by one in sorted order. In case a key is defined in multiple files, the occurrence in the last file takes precedence. The image contains a basic configuration 00_patroni.yaml.

Following configuration parameters should be set by the user of this image via environment variables or an additional config file:

• PATRONI_NAME
• PATRONI_SCOPE
• PATRONI_POSTGRESQL_CONNECT_ADDRESS
• PATRONI_RESTAPI_CONNECT_ADDRESS

Config file

This image can also be configured with the complete configuration in a config file /config/patroni.yml. If this file exists directory /config/patroni is not used.

patronictl

patronictl.yaml is no longer needed.

Customisation

Scripts can be run after bootstrapping by adding them to /post_init. When the image is configured with a config file instead of a config directory, the config file should contain option "post_init: /post-init.sh" in thte bootstrap section.
