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 routers. It accepts a ListOpts struct, which allows you to filter and sort the returned collection for greater efficiency.

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

Types

type AdminState

type AdminState *bool

AdminState gives users a solid type to work with for create and update operations. It is recommended that users use the `Up` and `Down` enums.

var (
	Up   AdminState = &iTrue
	Down AdminState = &iFalse
)

Convenience vars for AdminStateUp values.

type CreateOpts

type CreateOpts loadbalancerOpts

CreateOpts is the common options struct used in this package's Create operation.

func (CreateOpts) ToLoadbalancerCreateMap

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

ToLoadbalancerCreateMap casts a CreateOpts struct to a map.

type CreateOptsBuilder

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

CreateOptsBuilder is the interface options structs have to satisfy in order to be used in the main Create operation in this package. Since many extensions decorate or modify the common logic, it is useful for them to satisfy a basic interface in order for them to be used.

type CreateResult

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

CreateResult represents the result of a create operation.

func Create

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

Create is an operation which provisions a new loadbalancer 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 loadbalancers on behalf of other tenants by specifying a TenantID attribute different than their own.

func (CreateResult) Extract

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

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

func (CreateResult) ExtractStatuses

func (r CreateResult) ExtractStatuses() (*StatusTree, error)

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

type DeleteResult

type DeleteResult struct {
	gophercloud.ErrResult
}

DeleteResult represents the result of a delete operation.

func Delete

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

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

type GetResult

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

GetResult represents the result of a get operation.

func Get

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

Get retrieves a particular Loadbalancer based on its unique ID.

func GetStatuses

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

func (GetResult) Extract

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

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

func (GetResult) ExtractStatuses

func (r GetResult) ExtractStatuses() (*StatusTree, error)

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

type ListOpts

type ListOpts struct {
	Description        string `q:"description"`
	AdminStateUp       *bool  `q:"admin_state_up"`
	TenantID           string `q:"tenant_id"`
	ProvisioningStatus string `q:"provisioning_status"`
	VipAddress         string `q:"vip_address"`
	VipSubnetID        string `q:"vip_subnet_id"`
	ID                 string `q:"id"`
	OperatingStatus    string `q:"operating_status"`
	Name               string `q:"name"`
	Flavor             string `q:"flavor"`
	Provider           string `q:"provider"`
	Limit              int    `q:"limit"`
	Marker             string `q:"marker"`
	SortKey            string `q:"sort_key"`
	SortDir            string `q:"sort_dir"`
}

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 Loadbalancer attributes you want to see returned. SortKey allows you to sort by a particular attribute. SortDir sets the direction, and is either `asc' or `desc'. Marker and Limit are used for pagination.

func (ListOpts) ToLoadbalancerListQuery

func (opts ListOpts) ToLoadbalancerListQuery() (string, error)

ToLoadbalancerListQuery formats a ListOpts into a query string.

type ListOptsBuilder

type ListOptsBuilder interface {
	ToLoadbalancerListQuery() (string, error)
}

ListOptsBuilder allows extensions to add additional parameters to the List request.

type LoadBalancer

type LoadBalancer struct {
	// Human-readable description for the Loadbalancer.
	Description string `mapstructure:"description" json:"description"`

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

	// Owner of the LoadBalancer. Only an admin user can specify a tenant ID other than its own.
	TenantID string `mapstructure:"tenant_id" json:"tenant_id"`

	// The provisioning status of the LoadBalancer. This value is ACTIVE, PENDING_CREATE or ERROR.
	ProvisioningStatus string `mapstructure:"provisioning_status" json:"provisioning_status"`

	// The IP address of the Loadbalancer.
	VipAddress string `mapstructure:"vip_address" json:"vip_address"`

	// The UUID of the subnet on which to allocate the virtual IP for the Loadbalancer address.
	VipSubnetID string `mapstructure:"vip_subnet_id" json:"vip_subnet_id"`

	// The unique ID for the LoadBalancer.
	ID string `mapstructure:"id" json:"id"`

	// The operating status of the LoadBalancer. This value is ONLINE or OFFLINE.
	OperatingStatus string `mapstructure:"operating_status" json:"operating_status"`

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

	// The UUID of a flavor if set.
	Flavor string `mapstructure:"flavor" json:"flavor"`

	// The name of the provider.
	Provider string `mapstructure:"provider" json:"provider"`

	Listeners []listeners.Listener `mapstructure:"listeners" json:"listeners"`
}

LoadBalancer is the primary load balancing configuration object that specifies the virtual IP address on which client traffic is received, as well as other details such as the load balancing method to be use, protocol, etc.

func ExtractLoadbalancers

func ExtractLoadbalancers(page pagination.Page) ([]LoadBalancer, error)

ExtractLoadbalancers accepts a Page struct, specifically a LoadbalancerPage struct, and extracts the elements into a slice of LoadBalancer structs. In other words, a generic collection is mapped into a relevant slice.

type LoadbalancerPage

type LoadbalancerPage struct {
	pagination.LinkedPageBase
}

LoadbalancerPage is the page returned by a pager when traversing over a collection of routers.

func (LoadbalancerPage) IsEmpty

func (p LoadbalancerPage) IsEmpty() (bool, error)

IsEmpty checks whether a RouterPage struct is empty.

func (LoadbalancerPage) NextPageURL

func (p LoadbalancerPage) NextPageURL() (string, error)

NextPageURL is invoked when a paginated collection of routers has reached the end of a page and the pager seeks to traverse over a new one. In order to do this, it needs to construct the next page's URL.

type StatusTree

type StatusTree struct {
	Loadbalancer *LoadBalancer `mapstructure:"loadbalancer" json:"loadbalancer"`
}

type UpdateOpts

type UpdateOpts loadbalancerOpts

UpdateOpts is the common options struct used in this package's Update operation.

type UpdateOptsBuilder

type UpdateOptsBuilder interface {
	ToLoadbalancerUpdateMap() (map[string]interface{}, error)
}

UpdateOptsBuilder is the interface options structs have to satisfy in order to be used in the main Update operation in this package. Since many extensions decorate or modify the common logic, it is useful for them to satisfy a basic interface in order for them to be used.

type UpdateResult

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

UpdateResult represents the result of an update operation.

func Update

func Update(c *gophercloud.ServiceClient, id string, opts UpdateOpts) UpdateResult
