Functions

func Count

func Count() int64

Count returns a count of all nodes on this server.

func GetList

func GetList() []string

GetList gets a list of the nodes on this server.

func ImportStatus

func ImportStatus(nodeJSON map[string]interface{}) error

ImportStatus is used by the import function to import node statuses from the exported JSON dump.

Types

type Node

type Node struct {
	Name            string                 `json:"name"`
	ChefEnvironment string                 `json:"chef_environment"`
	RunList         []string               `json:"run_list"`
	JSONClass       string                 `json:"json_class"`
	ChefType        string                 `json:"chef_type"`
	Automatic       map[string]interface{} `json:"automatic"`
	Normal          map[string]interface{} `json:"normal"`
	Default         map[string]interface{} `json:"default"`
	Override        map[string]interface{} `json:"override"`
	// contains filtered or unexported fields
}

Node is a basic Chef node, holding the run list and attributes of the node.

func AllNodes

func AllNodes() []*Node

AllNodes returns all the nodes on the server

func Get

func Get(nodeName string) (*Node, util.Gerror)

Get a node.

func GetFromEnv

func GetFromEnv(envName string) ([]*Node, error)

GetFromEnv returns all nodes that belong to the given environment.

func GetMulti

func GetMulti(nodeNames []string) ([]*Node, util.Gerror)

GetMulti gets multiple nodes from a given slice of node names.

func GetNodesByStatus

func GetNodesByStatus(nodeNames []string, status string) ([]*Node, error)

GetNodesByStatus returns the nodes that currently have the given status.

func New

func New(name string) (*Node, util.Gerror)

New makes a new node.

func NewFromJSON

func NewFromJSON(jsonNode map[string]interface{}) (*Node, util.Gerror)

NewFromJSON creates a new node from the uploaded JSON.

func UnseenNodes

func UnseenNodes() ([]*Node, error)

UnseenNodes returns all nodes that have not sent status reports for a while.

func (*Node) AllStatuses

func (n *Node) AllStatuses() ([]*NodeStatus, error)
