keepalived

ansible-keepalived

This role configures keepalived without arm twisting. Write the configuration the way you want.

Automatic testing is provided using molecule's delegated driver and https://builds.sr.ht.

Requirements

Another role or deployment method must be devised to use notification scripts such as notify_backup, notify_fault and notify_master.

Role Variables

keepalived_global_defs: configure the global_defs block ;
keepalived_vrrp_scripts: configure one or more vrrp_script ;
keepalived_vrrp_instances: configure one or more vrrp_instance.
keepalived_virtual_servers: configure one or more virtual_servers.
keepalived_vrrp_sync_group: configure one or more vrrp_sync_group.
keepalived_flags: flags to pass to the keepalived daemon (set --log-detail --log-facility=7 by default)

Dependencies

The keepalived package should be installed first using a tool such as Packer. However if it is not part of your toolchain the variable keepalived_install can be set to True to provoke an installation.
