Overview

Package rules enables management and retrieval of Firewall Rules in the OpenStack Networking Service.

Example to List Rules

listOpts := rules.ListOpts{
	Protocol: rules.ProtocolAny,
}

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

allRules, err := rules.ExtractRules(allPages)
if err != nil {
	panic(err)
}

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

Example to Create a Rule

createOpts := rules.CreateOpts{
	Action:               "allow",
	Protocol:             rules.ProtocolTCP,
	Description:          "ssh",
	DestinationPort:      22,
	DestinationIPAddress: "192.168.1.0/24",
}

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

Example to Update a Rule

ruleID := "f03bd950-6c56-4f5e-a307-45967078f507"
newPort := 80
newDescription := "http"

updateOpts := rules.UpdateOpts{
	Description: &newDescription,
	port:        &newPort,
}

rule, err := rules.Update(networkClient, ruleID, updateOpts).Extract()
if err != nil {
	panic(err)
}

Example to Delete a Rule

ruleID := "f03bd950-6c56-4f5e-a307-45967078f507"
err := rules.Delete(networkClient, ruleID).ExtractErr()
if err != nil {
	panic(err)
}

Functions

func List

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

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

Types

type CreateOpts

type CreateOpts struct {
	Protocol             Protocol              `json:"protocol" required:"true"`

	Shared               *bool                 `json:"shared,omitempty"`
	Enabled              *bool                 `json:"enabled,omitempty"`
}

CreateOpts contains all the values needed to create a new firewall rule.

func (CreateOpts) ToRuleCreateMap

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

ToRuleCreateMap casts a CreateOpts struct to a map.

type CreateOptsBuilder

type CreateOptsBuilder interface {
	ToRuleCreateMap() (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 Rule.

func Create

Create accepts a CreateOpts struct and uses the values to create a new firewall rule.

func (CreateResult) Extract

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

Extract is a function that accepts a result and extracts a firewall rule.

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 firewall rule 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 Rule.

func Get

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

Get retrieves a particular firewall rule based on its unique ID.

func (GetResult) Extract

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

Extract is a function that accepts a result and extracts a firewall rule.

type ListOpts

type ListOpts struct {
	TenantID             string `q:"tenant_id"`
	ProjectID            string `q:"project_id"`
	Name                 string `q:"name"`
	Description          string `q:"description"`
	Protocol             string `q:"protocol"`
	Action               string `q:"action"`
	IPVersion            int    `q:"ip_version"`
	SourceIPAddress      string `q:"source_ip_address"`
	DestinationIPAddress string `q:"destination_ip_address"`
	SourcePort           string `q:"source_port"`
	DestinationPort      string `q:"destination_port"`
	Enabled              bool   `q:"enabled"`
	ID                   string `q:"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 Firewall rule attributes you want to see returned. SortKey allows you to sort by a particular firewall rule attribute. SortDir sets the direction, and is either `asc' or `desc'. Marker and Limit are used for pagination.

func (ListOpts) ToRuleListQuery

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

ToRuleListQuery formats a ListOpts into a query string.

type ListOptsBuilder

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

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

type Protocol

type Protocol string

Protocol represents a valid rule protocol.

const (
	// ProtocolAny is to allow any protocol.
	ProtocolAny Protocol = "any"

	// ProtocolICMP is to allow the ICMP protocol.
	ProtocolICMP Protocol = "icmp"

	// ProtocolTCP is to allow the TCP protocol.
	ProtocolTCP Protocol = "tcp"

	// ProtocolUDP is to allow the UDP protocol.
	ProtocolUDP Protocol = "udp"
)

type Rule

}

Rule represents a firewall rule.

func ExtractRules

func ExtractRules(r pagination.Page) ([]Rule, error)

ExtractRules accepts a Page struct, specifically a RulePage struct, and extracts the elements into a slice of Rule structs. In other words, a generic collection is mapped into a relevant slice.

type RulePage

type RulePage struct {
	pagination.LinkedPageBase
}

RulePage is the page returned by a pager when traversing over a collection of firewall rules.

func (RulePage) IsEmpty

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

IsEmpty checks whether a RulePage struct is empty.

func (RulePage) NextPageURL

func (r RulePage) NextPageURL() (string, error)

NextPageURL is invoked when a paginated collection of firewall rules 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 {
	Protocol             *string                `json:"protocol,omitempty"`
	Action               *string                `json:"action,omitempty"`
	Name                 *string                `json:"name,omitempty"`
	Description          *string                `json:"description,omitempty"`

	SourceIPAddress      *string                `json:"source_ip_address,omitempty"`
	DestinationIPAddress *string                `json:"destination_ip_address,omitempty"`
	SourcePort           *string                `json:"source_port,omitempty"`
	DestinationPort      *string                `json:"destination_port,omitempty"`
	Shared               *bool                  `json:"shared,omitempty"`
	Enabled              *bool                  `json:"enabled,omitempty"`
}

UpdateOpts contains the values used when updating a firewall rule. These fields are all pointers so that unset fields will not cause the existing Rule attribute to be removed.

func (UpdateOpts) ToRuleUpdateMap

func (opts UpdateOpts) ToRuleUpdateMap() (map[string]interface{}, error)

ToRuleUpdateMap casts a UpdateOpts struct to a map.

type UpdateOptsBuilder

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

UpdateOptsBuilder allows extensions to add additional parameters to the Update request.

type UpdateResult

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

UpdateResult represents the result of an update operation. Call its Extract method to interpret it as a Rule.

func Update

Update allows firewall policies to be updated.

func (UpdateResult) Extract

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

Extract is a function that accepts a result and extracts a firewall rule.
