Overview

Package ports contains functionality for working with Neutron port resources.

A port represents a virtual switch port on a logical network switch. Virtual instances attach their interfaces into ports. The logical port also defines the MAC address and the IP address(es) to be assigned to the interfaces plugged into them. When IP addresses are associated to a port, this also implies the port is associated with a subnet, as the IP address was taken from the allocation pool for a specific subnet.

Example to List Ports 

listOpts := ports.ListOpts{
	DeviceID: "b0b89efe-82f8-461d-958b-adbf80f50c7d",
}

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

allPorts, err := ports.ExtractPorts(allPages)
if err != nil {
	panic(err)
}

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

Example to Create a Port 

createOtps := ports.CreateOpts{
	Name:         "private-port",
	AdminStateUp: &asu,
	NetworkID:    "a87cc70a-3e15-4acf-8205-9b711a3531b7",
	FixedIPs: []ports.IP{
		{SubnetID: "a0304c3a-4f08-4c43-88af-d796509c97d2", IPAddress: "10.0.0.2"},
	},
	SecurityGroups: &[]string{"foo"},
	AllowedAddressPairs: []ports.AddressPair{
		{IPAddress: "10.0.0.4", MACAddress: "fa:16:3e:c9:cb:f0"},
	},
}

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

Example to Update a Port 

portID := "c34bae2b-7641-49b6-bf6d-d8e473620ed8"

updateOpts := ports.UpdateOpts{
	Name:           "new_name",
	SecurityGroups: &[]string{},
}

port, err := ports.Update(networkClient, portID, updateOpts).Extract()
if err != nil {
	panic(err)
}

Example to Delete a Port 

portID := "c34bae2b-7641-49b6-bf6d-d8e473620ed8"
err := ports.Delete(networkClient, portID).ExtractErr()
if err != nil {
	panic(err)
}

Functions

func ExtractPortsInto 

func ExtractPortsInto(r pagination.Page, v interface{}) error

func IDFromName 

func IDFromName(client *gophercloud.ServiceClient, name string) (string, error)

IDFromName is a convenience function that returns a port's ID, given its name.

func List 

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

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

Default policy settings return only those ports that are owned by the tenant who submits the request, unless the request is submitted by a user with administrative rights.
