Functions

func Asset 

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir 

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy: 

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo 

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames 

func AssetNames() []string

AssetNames returns the names of the assets.

func CreatePki 

func CreatePki(extraFQDNs []string, extraIPs []net.IP, clusterDomain string, caPair *PkiKeyCertPair) (*PkiKeyCertPair, *PkiKeyCertPair, *PkiKeyCertPair, error)

func FormatAzureProdFQDN 

func FormatAzureProdFQDN(fqdnPrefix string, location string) string

FormatAzureProdFQDN constructs an Azure prod fqdn

func FormatAzureProdFQDNs 

func FormatAzureProdFQDNs(fqdnPrefix string) []string

FormatAzureProdFQDNs constructs all possible Azure prod fqdn

func GenerateClusterID 

func GenerateClusterID(properties *api.Properties) string

GenerateClusterID creates a unique 8 string cluster ID

func GenerateKubeConfig 

func GenerateKubeConfig(properties *api.Properties, location string) (string, error)

GenerateKubeConfig returns a JSON string representing the KubeConfig

func GetClassicAllowedSizes 

func GetClassicAllowedSizes() string

func GetDCOSMasterAllowedSizes 

func GetDCOSMasterAllowedSizes() string

GetDCOSMasterAllowedSizes returns the master allowed sizes

func GetMasterAgentAllowedSizes 

func GetMasterAgentAllowedSizes() string

GetMasterAgentAllowedSizes returns the agent allowed sizes

func GetSizeMap 

func GetSizeMap() string

GetSizeMap returns the size / storage map

func MustAsset 

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func PrettyPrintArmTemplate 

func PrettyPrintArmTemplate(template string) (string, error)

PrettyPrintArmTemplate will pretty print the arm template ensuring ordered by params, vars, resources, and outputs

func PrettyPrintJSON 

func PrettyPrintJSON(content string) (string, error)

PrettyPrintJSON will pretty print the json into

func RestoreAsset 

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets 

func RestoreAssets(dir, name string) error
