Overview

Package rules provides information and interaction with Security Group Rules for the OpenStack Networking service.

Example to List Security Groups Rules 

listOpts := rules.ListOpts{
	Protocol: "tcp",
}

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 Security Group Rule 

createOpts := rules.CreateOpts{
	Direction:     "ingress",
	PortRangeMin:  80,
	EtherType:     rules.EtherType4,
	PortRangeMax:  80,
	Protocol:      "tcp",
	RemoteGroupID: "85cc3048-abc3-43cc-89b3-377341426ac5",
	SecGroupID:    "a7734e61-b545-452d-a3cd-0189cbd9747a",
}

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

Example to Delete a Security Group Rule 

ruleID := "37d94f8a-d136-465c-ae46-144f0d8ef141"
err := rules.Delete(networkClient, ruleID).ExtractErr()
if err != nil {
	panic(err)
}

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

Types

type CreateOpts 

type CreateOpts struct {
	// Must be either "ingress" or "egress": the direction in which the security
	// group rule is applied.
	Direction RuleDirection `json:"direction" required:"true"`

	// Must be "IPv4" or "IPv6", and addresses represented in CIDR must match the
	// ingress or egress rules.
	EtherType RuleEtherType `json:"ethertype" required:"true"`

	// The security group ID to associate with this security group rule.
	SecGroupID string `json:"security_group_id" required:"true"`

	// The maximum port number in the range that is matched by the security group
	// rule. The PortRangeMin attribute constrains the PortRangeMax attribute. If
	// the protocol is ICMP, this value must be an ICMP type.
	PortRangeMax int `json:"port_range_max,omitempty"`

	// The minimum port number in the range that is matched by the security group
	// rule. If the protocol is TCP or UDP, this value must be less than or equal
	// to the value of the PortRangeMax attribute. If the protocol is ICMP, this
	// value must be an ICMP type.
	PortRangeMin int `json:"port_range_min,omitempty"`

	// The protocol that is matched by the security group rule. Valid values are
	// "tcp", "udp", "icmp" or an empty string.
	Protocol RuleProtocol `json:"protocol,omitempty"`

	// The remote group ID to be associated with this security group rule. You can
	// specify either RemoteGroupID or RemoteIPPrefix.
	RemoteGroupID string `json:"remote_group_id,omitempty"`

	// The remote IP prefix to be associated with this security group rule. You can
	// specify either RemoteGroupID or RemoteIPPrefix. This attribute matches the
	// specified IP prefix as the source IP address of the IP packet.
	RemoteIPPrefix string `json:"remote_ip_prefix,omitempty"`

	// The UUID of the tenant who owns the Rule. Only administrative users
	// can specify a tenant UUID other than their own.
	TenantID string `json:"tenant_id,omitempty"`

	// Provides supplementary information about the security group rule.
	Description string `json:"description,omitempty"`
}

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

func (CreateOpts) ToSecGroupRuleCreateMap 

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

ToSecGroupRuleCreateMap builds a request body from CreateOpts.

type CreateOptsBuilder 

type CreateOptsBuilder interface {
	ToSecGroupRuleCreateMap() (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 SecGroupRule.

func Create 

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

Create is an operation which adds a new security group rule and associates it with an existing security group (whose ID is specified in CreateOpts).

func (CreateResult) Extract 

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

Extract is a function that accepts a result and extracts a security 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 security group 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 SecGroupRule.

func Get 

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

Get retrieves a particular security group rule based on its unique ID.

func (GetResult) Extract 

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

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

type ListOpts 

type ListOpts struct {
	Direction      string `q:"direction"`
	EtherType      string `q:"ethertype"`
	ID             string `q:"id"`
	PortRangeMax   int    `q:"port_range_max"`
	PortRangeMin   int    `q:"port_range_min"`
	Protocol       string `q:"protocol"`
	RemoteGroupID  string `q:"remote_group_id"`
	RemoteIPPrefix string `q:"remote_ip_prefix"`
	SecGroupID     string `q:"security_group_id"`
	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 security group rule 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 RuleDirection 

type RuleDirection string

type RuleEtherType 

type RuleEtherType string

type RuleProtocol 

type RuleProtocol string

type SecGroupRule 

type SecGroupRule struct {
	// The UUID for this security group rule.
	ID string `json:"id"`

	// The direction in which the security group rule is applied. The only values
	// allowed are "ingress" or "egress". For a compute instance, an ingress
	// security group rule is applied to incoming (ingress) traffic for that
	// instance. An egress rule is applied to traffic leaving the instance.
	Direction string `json:"direction"`

func ExtractRules 

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

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