/*
Package loadbalancers provides information and interaction with Load Balancers
of the LBaaS v2 extension for the OpenStack Networking service.
Example to List Load Balancers
listOpts := loadbalancers.ListOpts{
Provider: "haproxy",
}
allPages, err := loadbalancers.List(networkClient, listOpts).AllPages()
if err != nil {
panic(err)
}
allLoadbalancers, err := loadbalancers.ExtractLoadBalancers(allPages)
if err != nil {
panic(err)
}
for _, lb := range allLoadbalancers {
fmt.Printf("%+v\n", lb)
}
Example to Create a Load Balancer
createOpts := loadbalancers.CreateOpts{
Name: "db_lb",
AdminStateUp: gophercloud.Enabled,
VipSubnetID: "9cedb85d-0759-4898-8a4b-fa5a5ea10086",
VipAddress: "10.30.176.48",
FlavorID: "60df399a-ee85-11e9-81b4-2a2ae2dbcce4",
Provider: "haproxy",
Tags: []string{"test", "stage"},
}
lb, err := loadbalancers.Create(networkClient, createOpts).Extract()
if err != nil {
panic(err)
}
Example to Create a fully populated Load Balancer
createOpts := loadbalancers.CreateOpts{
Name: "db_lb",
AdminStateUp: gophercloud.Enabled,
VipSubnetID: "9cedb85d-0759-4898-8a4b-fa5a5ea10086",
VipAddress: "10.30.176.48",
FlavorID: "60df399a-ee85-11e9-81b4-2a2ae2dbcce4",
Provider: "haproxy",
Tags: []string{"test", "stage"},
Listeners: []listeners.CreateOpts{{
Protocol: "HTTP",
ProtocolPort: 8080,
Name: "redirect_listener",
L7Policies: []l7policies.CreateOpts{{
Name: "redirect-example.com",
Action: l7policies.ActionRedirectToURL,
RedirectURL: "http://www.example.com",
Rules: []l7policies.CreateRuleOpts{{
RuleType: l7policies.TypePath,
CompareType: l7policies.CompareTypeRegex,
Value: "/images*",
}},
}},
DefaultPool: &pools.CreateOpts{
LBMethod: pools.LBMethodRoundRobin,
Protocol: "HTTP",
Name: "example pool",
Members: []pools.BatchUpdateMemberOpts{{

MaxRetries: 2,
Timeout: 1,
},
},
}},
}
lb, err := loadbalancers.Create(networkClient, createOpts).Extract()
if err != nil {
panic(err)
}
Example to Update a Load Balancer
lbID := "d67d56a6-4a86-4688-a282-f46444705c64"
name := "new-name"
updateOpts := loadbalancers.UpdateOpts{
Name: &name,
}
lb, err := loadbalancers.Update(networkClient, lbID, updateOpts).Extract()
if err != nil {
panic(err)
}
Example to Delete a Load Balancers
deleteOpts := loadbalancers.DeleteOpts{
Cascade: true,
}
lbID := "d67d56a6-4a86-4688-a282-f46444705c64"
err := loadbalancers.Delete(networkClient, lbID, deleteOpts).ExtractErr()
if err != nil {
panic(err)
}
Example to Get the Status of a Load Balancer
lbID := "d67d56a6-4a86-4688-a282-f46444705c64"
status, err := loadbalancers.GetStatuses(networkClient, LBID).Extract()
if err != nil {
panic(err)
}
Example to Get the Statistics of a Load Balancer
lbID := "d67d56a6-4a86-4688-a282-f46444705c64"
stats, err := loadbalancers.GetStats(networkClient, LBID).Extract()
if err != nil {
panic(err)
}
Example to Failover a Load Balancers
lbID := "d67d56a6-4a86-4688-a282-f46444705c64"
err := loadbalancers.Failover(networkClient, lbID).ExtractErr()
if err != nil {
panic(err)
}
