Overview

Package loadbalancer contains functionality for working GCLoud loadbalancers API resources

Example to List LoadBalancer 

listOpts := loadbalancers.ListOpts{
}

allPages, err := loadbalancers.List(loadbalancerClient).AllPages()
if err != nil {
	panic(err)
}

allLoadBalancers, err := loadbalancers.ExtractLoadBalancers(allPages)
if err != nil {
	panic(err)
}

for _, loadbalancer := range allLoadBalancers {
	fmt.Printf("%+v", loadbalancer)
}

Example to Create a LoadBalancer 

createOpts := loadbalancers.CreateOpts{
}

loadbalancers, err := loadbalancers.Create(loadbalancerClient, createOpts).Extract()
if err != nil {
	panic(err)
}

Example to Delete a LoadBalancer 

loadbalancerID := "484cda0e-106f-4f4b-bb3f-d413710bbe78"
err := loadbalancers.Delete(loadbalancerClient, loadbalancerID).ExtractErr()
if err != nil {
	panic(err)
}
