Functions

func AssertStructValid 

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 

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

func DecodeContent 

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

func DecodeGzipContent 

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

func DecompressGzip added in v1.4.1 

func DecompressGzip(content []byte) ([]byte, error)

func IsCloudConfig 

func IsCloudConfig(userdata string) bool

func IsIgnitionConfig 

func IsIgnitionConfig(userdata string) bool

func IsScript 

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) Decode 

func (cc *CloudConfig) Decode() error

Decode decodes the content of cloud config. Currently only WriteFiles section supports several types of encoding and all of them are supported. After decode operation, Encoding type is unset.

func (CloudConfig) String 

func (cc CloudConfig) String() string

type CoreOS 

type CoreOS struct {
	Etcd      Etcd      `yaml:"etcd"`
	Etcd2     Etcd2     `yaml:"etcd2"`
	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 

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 

func (e ErrorValid) Error() string

type EtcHosts 

type EtcHosts string
