repmgr ====== TPA will install repmgr on all postgres instances that have the ``failover_manager`` instance variable set to ``repmgr`` ; this is the default setting. The directory of the ``repmgr`` configuration file defaults to ``/etc/repmgr/`` , where ```` is the major version of postgres being installed on this instance, but can be changed by setting the ``repmgr_conf_dir`` variable for the instance. The configuration file itself is always called ``repmgr.conf`` . The default repmgr configuration will set up automatic failover between instances configured with the role ``primary`` and the role ``replica`` . repmgr package version ---------------------- By default, TPA installs the latest available version of repmgr. The version of the repmgr package that is installed can be specified by including ``repmgr_package_version: xxx`` under the ``cluster_vars`` section of the ``config.yml`` file. .. code:: yaml cluster_vars: … repmgr_package_version: 4.0.5-1.pgdg90+1 … You may use any version specifier that apt or yum would accept. If your version does not match, try appending a ``*`` wildcard. This is often necessary when the package version has an epoch qualifier like ``2:...`` . repmgr configuration -------------------- The following instance variables can be set: ``repmgr_priority`` : sets ``priority`` in the config file ``repmgr_location`` : sets ``location`` in the config file ``repmgr_reconnect_attempts`` : sets ``reconnect_attempts`` in the config file, default ``6`` ``repmgr_reconnect_interval`` : sets ``reconnect_interval`` in the config file, default ``10`` ``repmgr_use_slots`` : sets ``use_replication_slots`` in the config file, default ``1`` ``repmgr_failover`` : sets ``failover`` in the config file, default ``automatic`` Any extra settings in ``repmgr_conf_settings`` will also be passed through into the repmgr config file. repmgr on PGD instances ----------------------- On PGD instances, ``repmgr_failover`` will be set to ``manual`` by default.
