Types

type ArchFingerprint

type ArchFingerprint struct {
	// contains filtered or unexported fields
}

ArchFingerprint is used to fingerprint the architecture

func (*ArchFingerprint) Fingerprint

func (f *ArchFingerprint) Fingerprint(config *client.Config, node *structs.Node) (bool, error)

type CPUFingerprint

type CPUFingerprint struct {
	// contains filtered or unexported fields
}

CPUFingerprint is used to fingerprint the CPU

func (*CPUFingerprint) Fingerprint

func (f *CPUFingerprint) Fingerprint(cfg *config.Config, node *structs.Node) (bool, error)

type ConsulFingerprint

type ConsulFingerprint struct {
	// contains filtered or unexported fields
}

ConsulFingerprint is used to fingerprint the architecture

func (*ConsulFingerprint) Fingerprint

func (f *ConsulFingerprint) Fingerprint(config *client.Config, node *structs.Node) (bool, error)

type EnvAWSFingerprint

type EnvAWSFingerprint struct {
	// contains filtered or unexported fields
}

EnvAWSFingerprint is used to fingerprint the CPU

func (*EnvAWSFingerprint) Fingerprint

func (f *EnvAWSFingerprint) Fingerprint(cfg *config.Config, node *structs.Node) (bool, error)

type Factory

type Factory func(*log.Logger) Fingerprint

Factory is used to instantiate a new Fingerprint

type Fingerprint

type Fingerprint interface {
	// Fingerprint is used to update properties of the Node,
	// and returns if the fingerprint was applicable and a potential error.
	Fingerprint(*config.Config, *structs.Node) (bool, error)
}

Fingerprint is used for doing "fingerprinting" of the host to automatically determine attributes, resources, and metadata about it. Each of these is a heuristic, and many of them can be applied on a particular host.

func NewArchFingerprint

func NewConsulFingerprint

func NewConsulFingerprint(logger *log.Logger) Fingerprint

NewConsulFingerprint is used to create an OS fingerprint

func NewEnvAWSFingerprint

func NewEnvAWSFingerprint(logger *log.Logger) Fingerprint

NewEnvAWSFingerprint is used to create a CPU fingerprint

func NewFingerprint

func NewFingerprint(name string, logger *log.Logger) (Fingerprint, error)
