Functions

func AssertStructValid added in v0.11.0 

func AssertStructValid(c interface{}) error

AssertStructValid checks the fields in the structure and makes sure that they contain valid values as specified by the 'valid' flag. Empty fields are implicitly valid.

func DecodeBase64Content added in v1.2.0 

func DecodeBase64Content(content string) ([]byte, error)

func DecodeContent added in v1.2.0 

func DecodeContent(content string, encoding string) ([]byte, error)

func DecodeGzipContent added in v1.2.0 

func DecodeGzipContent(content string) ([]byte, error)

func IsCloudConfig added in v0.11.0 

func IsCloudConfig(userdata string) bool

func IsScript added in v0.11.0 

func IsScript(userdata string) bool

func IsZero 

func IsZero(c interface{}) bool

IsZero returns whether or not the parameter is the zero value for its type. If the parameter is a struct, only the exported fields are considered.

Types

type CloudConfig 

type CloudConfig struct {
	SSHAuthorizedKeys []string `yaml:"ssh_authorized_keys"`
	CoreOS            CoreOS   `yaml:"coreos"`
	WriteFiles        []File   `yaml:"write_files"`
	Hostname          string   `yaml:"hostname"`
	Users             []User   `yaml:"users"`
	ManageEtcHosts    EtcHosts `yaml:"manage_etc_hosts"`
}

CloudConfig encapsulates the entire cloud-config configuration file and maps directly to YAML. Fields that cannot be set in the cloud-config (fields used for internal use) have the YAML tag '-' so that they aren't marshalled.

func NewCloudConfig 

func NewCloudConfig(contents string) (*CloudConfig, error)

NewCloudConfig instantiates a new CloudConfig from the given contents (a string of YAML), returning any error encountered. It will ignore unknown fields but log encountering them.

func (CloudConfig) String 

func (cc CloudConfig) String() string

type CoreOS added in v1.1.0 

type CoreOS struct {
	Etcd      Etcd      `yaml:"etcd"`
	Flannel   Flannel   `yaml:"flannel"`
	Fleet     Fleet     `yaml:"fleet"`
	Locksmith Locksmith `yaml:"locksmith"`
	OEM       OEM       `yaml:"oem"`
	Update    Update    `yaml:"update"`
	Units     []Unit    `yaml:"units"`
}

type ErrorValid added in v0.11.0 

type ErrorValid struct {
	Value string
	Valid string
	Field string
}

func AssertValid 

func AssertValid(value reflect.Value, valid string) *ErrorValid

AssertValid checks to make sure that the given value is in the list of valid values. Zero values are implicitly valid.

func (ErrorValid) Error added in v0.11.0 

func (e ErrorValid) Error() string

type EtcHosts 

type EtcHosts string
