Functions

func List 

func List(c *gophercloud.ServiceClient, opts ListOpts) 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 AddInterfaceOpts 

type AddInterfaceOpts struct {
	SubnetID string `json:"subnet_id,omitempty" xor:"PortID"`
	PortID   string `json:"port_id,omitempty" xor:"SubnetID"`
}

AddInterfaceOpts represents the options for adding an interface to a router.

func (AddInterfaceOpts) ToRouterAddInterfaceMap 

func (opts AddInterfaceOpts) ToRouterAddInterfaceMap() (map[string]interface{}, error)

ToRouterAddInterfaceMap builds a request body from AddInterfaceOpts.

type AddInterfaceOptsBuilder 

type AddInterfaceOptsBuilder interface {
	ToRouterAddInterfaceMap() (map[string]interface{}, error)
}

AddInterfaceOptsBuilder allows extensions to add additional parameters to the AddInterface request.

type CreateOpts 

type CreateOpts struct {
	Name                  string       `json:"name,omitempty"`
	AdminStateUp          *bool        `json:"admin_state_up,omitempty"`
	Distributed           *bool        `json:"distributed,omitempty"`
	TenantID              string       `json:"tenant_id,omitempty"`

	Ha                    *bool        `json:"ha,omitempty"`
}

CreateOpts contains all the values needed to create a new router. There are no required values.

func (CreateOpts) ToRouterCreateMap 

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

ToRouterCreateMap builds a create request body from CreateOpts.

type CreateOptsBuilder 

type CreateOptsBuilder interface {
	ToRouterCreateMap() (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 Router.

func Create 

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

Create accepts a CreateOpts struct and uses the values to create a new logical router. When it is created, the router does not have an internal interface - it is not associated to any subnet.

You can optionally specify an external gateway for a router using the GatewayInfo struct. The external gateway for the router must be plugged into an external network (it is external if its `router:external' field is set to true).

func (CreateResult) Extract 

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

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

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 router based on its unique ID.

type ExternalFixedIP 

type ExternalFixedIP struct {
	IPAddress string `json:"ip_address"`
	SubnetID  string `json:"subnet_id"`
}

ExternalFixedIP is the IP address and subnet ID of the external gateway of a router.

type GatewayInfo 

type GatewayInfo struct {
	NetworkID        string            `json:"network_id"`
	EnableSNAT       *bool             `json:"enable_snat,omitempty"`
	ExternalFixedIPs []ExternalFixedIP `json:"external_fixed_ips,omitempty"`
}

GatewayInfo represents the information of an external gateway for any particular network router.

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 Router.

func Get 

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

Get retrieves a particular router based on its unique ID.

func (GetResult) Extract 

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

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

type InterfaceInfo 

type InterfaceInfo struct {
	// SubnetID is the ID of the subnet which this interface is associated with.
	SubnetID string `json:"subnet_id"`

	// PortID is the ID of the port that is a part of the subnet.
	PortID string `json:"port_id"`

	// ID is the UUID of the interface.
	ID string `json:"id"`

	// TenantID is the owner of the interface.
	TenantID string `json:"tenant_id"`
}

InterfaceInfo represents information about a particular router interface. As mentioned above, in order for a router to forward to a subnet, it needs an interface.

type InterfaceResult 

type InterfaceResult struct {
	gophercloud.Result
}

InterfaceResult represents the result of interface operations, such as AddInterface() and RemoveInterface(). Call its Extract method to interpret the result as a InterfaceInfo.

func AddInterface 

func AddInterface(c *gophercloud.ServiceClient, id string, opts AddInterfaceOptsBuilder) (r InterfaceResult)

AddInterface attaches a subnet to an internal router interface. You must specify either a SubnetID or PortID in the request body. If you specify both, the operation will fail and an error will be returned.

If you specify a SubnetID, the gateway IP address for that particular subnet is used to create the router interface. Alternatively, if you specify a PortID, the IP address associated with the port is used to create the router interface.

If you reference a port that is associated with multiple IP addresses, or if the port is associated with zero IP addresses, the operation will fail and a 400 Bad Request error will be returned.

If you reference a port already in use, the operation will fail and a 409 Conflict error will be returned.

The PortID that is returned after using Extract() on the result of this operation can either be the same PortID passed in or, on the other hand, the identifier of a new port created by this operation. After the operation completes, the device ID of the port is set to the router ID, and the device owner attribute is set to `network:router_interface'.

func RemoveInterface 

func RemoveInterface(c *gophercloud.ServiceClient, id string, opts RemoveInterfaceOptsBuilder) (r InterfaceResult)

RemoveInterface removes an internal router interface, which detaches a subnet from the router. You must specify either a SubnetID or PortID, since these values are used to identify the router interface to remove.

Unlike AddInterface, you can also specify both a SubnetID and PortID. If you choose to specify both, the subnet ID must correspond to the subnet ID of the first IP address on the port specified by the port ID. Otherwise, the operation will fail and return a 409 Conflict error.

If the router, subnet or port which are referenced do not exist or are not visible to you, the operation will fail and a 404 Not Found error will be returned. After this operation completes, the port connecting the router with the subnet is removed from the subnet for the network.

func (InterfaceResult) Extract 

func (r InterfaceResult) Extract() (*InterfaceInfo, error)

Extract is a function that accepts a result and extracts an information struct.

type ListOpts 

type ListOpts struct {
	ID           string `q:"id"`
	Name         string `q:"name"`
	AdminStateUp *bool  `q:"admin_state_up"`
	Distributed  *bool  `q:"distributed"`
	Status       string `q:"status"`
	TenantID     string `q:"tenant_id"`
	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 floating IP attributes you want to see returned. SortKey allows you to sort by a particular network attribute. SortDir sets the direction, and is either `asc' or `desc'. Marker and Limit are used for pagination.

type RemoveInterfaceOpts 

type RemoveInterfaceOpts struct {
	SubnetID string `json:"subnet_id,omitempty" or:"PortID"`
	PortID   string `json:"port_id,omitempty" or:"SubnetID"`
}

RemoveInterfaceOpts represents options for removing an interface from a router.

func (RemoveInterfaceOpts) ToRouterRemoveInterfaceMap 

func (opts RemoveInterfaceOpts) ToRouterRemoveInterfaceMap() (map[string]interface{}, error)

ToRouterRemoveInterfaceMap builds a request body based on RemoveInterfaceOpts.

type RemoveInterfaceOptsBuilder 

type RemoveInterfaceOptsBuilder interface {
	ToRouterRemoveInterfaceMap() (map[string]interface{}, error)
}

RemoveInterfaceOptsBuilder allows extensions to add additional parameters to the RemoveInterface request.

type Route 

type Route struct {
	NextHop         string `json:"nexthop"`
	DestinationCIDR string `json:"destination"`
}

Route is a possible route in a router.

type Router 

type Router struct {
	// Status indicates whether or not a router is currently operational.
	Status string `json:"status"`

	// GateayInfo provides information on external gateway for the router.
	GatewayInfo GatewayInfo `json:"external_gateway_info"`

	// AdminStateUp is the administrative state of the router.
	AdminStateUp bool `json:"admin_state_up"`

	// Distributed is whether router is disitrubted or not.
	Distributed bool `json:"distributed"`

	// Name is the human readable name for the router. It does not have to be
	// unique.
	Name string `json:"name"`

	// ID is the unique identifier for the router.
	ID string `json:"id"`

	// TenantID is the owner of the router. Only admin users can specify a tenant
	// identifier other than its own.
	TenantID string `json:"tenant_id"`

	// Routes are a collection of static routes that the router will host.
	Routes []Route `json:"routes"`

	// Availability zone hints groups network nodes that run services like DHCP, L3, FW, and others.
	// Used to make network resources highly available.
	AvailabilityZoneHints []string `json:"availability_zone_hints"`

	// Specifies the HA deployment mode.
	// Administrator permission required.
	Ha bool `json:"ha,omitempty"`
}

Router represents a Neutron router. A router is a logical entity that forwards packets across internal subnets and NATs (network address translation) them on external networks through an appropriate gateway.

A router has an interface for each subnet with which it is associated. By default, the IP address of such interface is the subnet's gateway IP. Also, whenever a router is associated with a subnet, a port for that router interface is added to the subnet's network.

func ExtractRouters 

func ExtractRouters(r pagination.Page) ([]Router, error)

ExtractRouters accepts a Page struct, specifically a RouterPage struct, and extracts the elements into a slice of Router structs. In other words, a generic collection is mapped into a relevant slice.

type RouterPage 

type RouterPage struct {
	pagination.LinkedPageBase
}

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

func (RouterPage) IsEmpty 

func (r RouterPage) IsEmpty() (bool, error)

IsEmpty checks whether a RouterPage struct is empty.

func (RouterPage) NextPageURL 

func (r RouterPage) 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 UpdateOpts 

type UpdateOpts struct {
	Name         string       `json:"name,omitempty"`
	AdminStateUp *bool        `json:"admin_state_up,omitempty"`

Update allows routers to be updated. You can update the name, administrative state, and the external gateway. For more information about how to set the external gateway for a router, see Create. This operation does not enable the update of router interfaces. To do this, use the AddInterface and RemoveInterface functions.

func (UpdateResult) Extract 

func (r UpdateResult) Extract() (*Router, error)

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