Overview

Package listeners provides information and interaction with Listeners of the LBaaS v2 extension for the OpenStack Networking service.

Example to List Listeners 

listOpts := listeners.ListOpts{
	LoadbalancerID : "ca430f80-1737-4712-8dc6-3f640d55594b",
}

allPages, err := listeners.List(networkClient, listOpts).AllPages()
if err != nil {
	panic(err)
}

allListeners, err := listeners.ExtractListeners(allPages)
if err != nil {
	panic(err)
}

for _, listener := range allListeners {
	fmt.Printf("%+v\n", listener)
}

Example to Create a Listener 

createOpts := listeners.CreateOpts{
	Protocol:               "TCP",
	Name:                   "db",
	LoadbalancerID:         "79e05663-7f03-45d2-a092-8b94062f22ab",
	AdminStateUp:           gophercloud.Enabled,
	DefaultPoolID:          "41efe233-7591-43c5-9cf7-923964759f9e",
	ProtocolPort:           3306,
}

listener, err := listeners.Create(networkClient, createOpts).Extract()
if err != nil {
	panic(err)
}

Example to Update a Listener 

listenerID := "d67d56a6-4a86-4688-a282-f46444705c64"

i1001 := 1001
updateOpts := listeners.UpdateOpts{
	ConnLimit: &i1001,
}

listener, err := listeners.Update(networkClient, listenerID, updateOpts).Extract()
if err != nil {
	panic(err)
}

Example to Delete a Listener 

listenerID := "d67d56a6-4a86-4688-a282-f46444705c64"
err := listeners.Delete(networkClient, listenerID).ExtractErr()
if err != nil {
	panic(err)
}

Functions

func List 

func List(c *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager

List returns a Pager which allows you to iterate over a collection of listeners. It accepts a ListOpts struct, which allows you to filter and sort the returned collection for greater efficiency.

Default policy settings return only those listeners that are owned by the tenant who submits the request, unless an admin user submits the request.

Types

type CreateOpts 

type CreateOpts struct {
	// Human-readable name for the Listener. Does not have to be unique.
	Name string `json:"name,omitempty"`

	// to create a pool for another tenant.
	TenantID string `json:"tenant_id,omitempty"`

}

CreateOpts represents options for creating a listener.

func (CreateOpts) ToListenerCreateMap 

func (opts CreateOpts) ToListenerCreateMap() (map[string]interface{}, error)

ToListenerCreateMap builds a request body from CreateOpts.

}

CreateResult represents the result of a create operation. Call its Extract method to interpret it as a Listener.

func Create 

func Create(c *gophercloud.ServiceClient, opts CreateOptsBuilder) (r CreateResult)

Create is an operation which provisions a new Listeners based on the configuration defined in the CreateOpts struct. Once the request is validated and progress has started on the provisioning process, a CreateResult will be returned.

Users with an admin role can create Listeners on behalf of other tenants by specifying a TenantID attribute different than their own.

func (CreateResult) Extract 

func (r CreateResult) Extract() (*Listener, error)

Extract is a function that accepts a result and extracts a listener.

type DeleteResult 

type DeleteResult struct {
	gophercloud.ErrResult
}

func Delete 

func Delete(c *gophercloud.ServiceClient, id string) (r DeleteResult)

Delete will permanently delete a particular Listeners based on its unique ID.

type GetResult 

type GetResult struct {
	// contains filtered or unexported fields
}

func Get 

func Get(c *gophercloud.ServiceClient, id string) (r GetResult)

Get retrieves a particular Listeners based on its unique ID.

func (GetResult) Extract 

func (r GetResult) Extract() (*Listener, error)

Extract is a function that accepts a result and extracts a listener.

type ListOpts 

type ListOpts struct {
	ID                      string `q:"id"`
	Name                    string `q:"name"`
	Description             string `q:"description"`
	DefaultPoolID           string `q:"default_pool_id"`
	Protocol                string `q:"protocol"`
	ProtocolPort            int    `q:"protocol_port"`
	Limit                   int    `q:"limit"`
	Marker                  string `q:"marker"`
	PageReverse             *bool  `q:"page_reverse"`
	DefaultTlsContainerRef  string `q:"default_tls_container_ref"`

	MemberAddress           string `q:"member_address"`
	MemberDeviceID          string `q:"member_device_id"`
}

ListOpts allows the filtering and sorting of paginated collections through the API. Filtering is achieved by passing in struct field values that map to the floating IP attributes you want to see returned. SortKey allows you to sort by a particular listener attribute. SortDir sets the direction, and is either `asc' or `desc'. Marker and Limit are used for pagination.

	ID string `json:"id"`

	// Owner of the Listener.
	TenantID string `json:"tenant_id"`

	// Human-readable name for the Listener. Does not have to be unique.
	Name string `json:"name"`
