Overview

Package stackresources provides operations for working with stack resources. A resource is a template artifact that represents some component of your desired architecture (a Cloud Server, a group of scaled Cloud Servers, a load balancer, some configuration management system, and so forth).

Example of get resource information in stack

rsrc_result := stackresources.Get(client, stack.Name, stack.ID, rsrc.Name)
if rsrc_result.Err != nil {
    panic(rsrc_result.Err)
}
rsrc, err := rsrc_result.Extract()
if err != nil {
    panic(err)
}

Example for list stack resources

all_stack_rsrc_pages, err := stackresources.List(client, stack.Name, stack.ID, nil).AllPages()
if err != nil {
    panic(err)
}

all_stack_rsrcs, err := stackresources.ExtractResources(all_stack_rsrc_pages)
if err != nil {
    panic(err)
}

fmt.Println("Resource List:")
for _, rsrc := range all_stack_rsrcs {
    // Get information of a resource in stack
    rsrc_result := stackresources.Get(client, stack.Name, stack.ID, rsrc.Name)
    if rsrc_result.Err != nil {
        panic(rsrc_result.Err)
    }
    rsrc, err := rsrc_result.Extract()
    if err != nil {
        panic(err)
    }
    fmt.Println("Resource Name: ", rsrc.Name, ", Physical ID: ", rsrc.PhysicalID, ", Status: ", rsrc.Status)
}

Example for get resource type schema

schema_result := stackresources.Schema(client, "OS::Heat::Stack")
if schema_result.Err != nil {
    panic(schema_result.Err)
}
schema, err := schema_result.Extract()
if err != nil {
    panic(err)
}
fmt.Println("Schema for resource type OS::Heat::Stack")
fmt.Println(schema.SupportStatus)

Example for get resource type Template

tmp_result := stackresources.Template(client, "OS::Heat::Stack")
if tmp_result.Err != nil {
    panic(tmp_result.Err)
}
tmp, err := tmp_result.Extract()
if err != nil {
    panic(err)
}
fmt.Println("Template for resource type OS::Heat::Stack")
fmt.Println(string(tmp))

Functions

func List

func List(client *gophercloud.ServiceClient, stackName, stackID string, opts ListOptsBuilder) pagination.Pager

List makes a request against the API to list resources for the given stack.

func ListTypes

func ListTypes(client *gophercloud.ServiceClient) pagination.Pager

ListTypes makes a request against the API to list resource types.

Types

type FindResult

type FindResult struct {
	gophercloud.Result
}

FindResult represents the result of a Find operation.

func Find

func Find(c *gophercloud.ServiceClient, stackName string) (r FindResult)

Find retrieves stack resources for the given stack name.

func (FindResult) Extract

func (r FindResult) Extract() ([]Resource, error)

Extract returns a slice of Resource objects and is called after a Find operation.

type GetResult

type GetResult struct {
	gophercloud.Result
}

GetResult represents the result of a Get operation.

func Get

func Get(c *gophercloud.ServiceClient, stackName, stackID, resourceName string) (r GetResult)

Get retreives data for the given stack resource.

func (GetResult) Extract

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

Extract returns a pointer to a Resource object and is called after a Get operation.

type ListOpts

type ListOpts struct {
	// Include resources from nest stacks up to Depth levels of recursion.
	Depth int `q:"nested_depth"`
}

ListOpts allows the filtering and sorting of paginated collections through the API. Marker and Limit are used for pagination.

func (ListOpts) ToStackResourceListQuery

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

ToStackResourceListQuery formats a ListOpts into a query string.

type ListOptsBuilder

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

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

type MetadataResult

type MetadataResult struct {
	gophercloud.Result
}

MetadataResult represents the result of a Metadata operation.

func Metadata

func Metadata(c *gophercloud.ServiceClient, stackName, stackID, resourceName string) (r MetadataResult)

Metadata retreives the metadata for the given stack resource.

func (MetadataResult) Extract

func (r MetadataResult) Extract() (map[string]string, error)

Extract returns a map object and is called after a Metadata operation.

type Resource

type Resource struct {
	Attributes   map[string]interface{} `json:"attributes"`
	CreationTime time.Time              `json:"-"`
	Description  string                 `json:"description"`
	Links        []gophercloud.Link     `json:"links"`
	LogicalID    string                 `json:"logical_resource_id"`
