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,
	Tags:                   []string{"test", "stage"},
}

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
i181000 := 181000
newTags := []string{"prod"}
updateOpts := listeners.UpdateOpts{
	ConnLimit: &i1001,
	TimeoutClientData: &i181000,
	TimeoutMemberData: &i181000,
	Tags: &newTags,
}

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)
}

Example to Get the Statistics of a Listener 

listenerID := "d67d56a6-4a86-4688-a282-f46444705c64"
stats, err := listeners.GetStats(networkClient, listenerID).Extract()
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 project who submits the request, unless an admin user submits the request.

Types

type CreateOpts 

type CreateOpts struct {
	// The protocol - can either be TCP, SCTP, HTTP, HTTPS or TERMINATED_HTTPS.
	Protocol Protocol `json:"protocol" required:"true"`

	// Human-readable description for the Listener.
	Description string `json:"description,omitempty"`

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

	// The load balancer on which to provision this listener.
	LoadbalancerID string `json:"loadbalancer_id" required:"true"`

	// The administrative state of the Listener. A valid value is true (UP)
	// or false (DOWN).
	AdminStateUp bool `json:"admin_state_up,omitempty"`

	// The maximum number of connections allowed for the Listener.
	ConnLimit int `json:"connection_limit,omitempty"`

	// The port on which to listen for client traffic.
	ProtocolPort int `json:"protocol_port" required:"true"`
}

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.

type CreateOptsBuilder 

type CreateOptsBuilder interface {
	ToListenerCreateMap() (map[string]interface{}, error)
}

CreateOptsBuilder allows extensions to add additional parameters to the Create request.

type CreateResult 

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

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 projects by specifying a ProjectID 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
}

DeleteResult represents the result of a delete operation. Call its ExtractErr method to determine if the request succeeded or failed.

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
}

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

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 {
	DefaultPoolID    string `q:"default_pool_id"`
	Protocol         string `q:"protocol"`
	Description      string `q:"description"`
	Name             string `q:"name"`
	AdminStateUp     bool   `q:"admin_state_up"`

	ProtocolPort     int    `q:"protocol_port"`
	ID               string `q:"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.

	// The maximum number of connections allowed for the Loadbalancer.
	// Default is -1, meaning no limit.
	ConnLimit int `json:"connection_limit"`

	// Timeout in milliseconds
	KeepaliveTimeout int `json:"keepalive_timeout"`

	// A reference to a Barbican container of TLS secrets.
	DefaultTlsContainerRef string `json:"default_tls_container_ref"`

	// The list of references to TLS secrets.
