gce_lb – create/destroy GCE load-balancer resources

Synopsis

  • This module can create and destroy Google Compute Engine loadbalancer and httphealthcheck resources. The primary LB resource is the load_balancer resource and the health check parameters are all prefixed with httphealthcheck. The full documentation for Google Compute Engine load balancing is at https://developers.google.com/compute/docs/load-balancing/. However, the ansible module simplifies the configuration by following the libcloud model. Full install/configuration instructions for the gce* modules can be found in the comments of ansible/test/gce_tests.py.
