Loadbalancer
For the manage-loadbalancer
play to work, the internal control socket
of the HAProxy service must be set to admin level. As of OSISM 7.0.6 this
is the default. Before this, the parameter haproxy_socket_level_admin
must
be added to the configuration repository and then a reconfigure
(osism apply -a reconfigure loadbalancer
) must be done for the loadbalancer
service.
haproxy_socket_level_admin: "yes"
You can check in the HAProxy configuration whether the control socket is configured correctly.
