keepalived_use_latest_stable: True
The HAProxy playbook makes use of the variable file
``vars/configs/keepalived_haproxy.yml``, and feeds its content
to the keepalived role, for keepalived master and backup nodes.
The HAProxy playbook reads the ``vars/configs/keepalived_haproxy.yml``
variable file and provides its content to the keepalived role for
keepalived master and backup nodes.
You can use your own variable file by setting
the path in your ``/etc/openstack_deploy/user_variables.yml``:
Keepalived pings a public IP address to check its status. The default
address is ``193.0.14.129``. To change this default, for example to
your gateway, set the ``keepalived_ping_address`` variable in the
``user_variables.yml`` file.
.. note:: The keepalived test works with IPv4 addresses only.
You can define additional variables to adapt keepalived to the
deployed environment. Refer to the ``user_variables.yml`` file for
more information. Optionally, you can use your own variable file, as
follows:
.. code-block:: yaml
haproxy_keepalived_vars_file:
haproxy_keepalived_vars_file: /path/to/myvariablefile.yml
