Functions

func GetHomePath

func GetHomePath() string

Types

type EnvProvider

type EnvProvider struct{}

func (*EnvProvider) Resolve

func (p *EnvProvider) Resolve() (auth.Credential, error)

type InstanceCredentialsProvider

type InstanceCredentialsProvider struct{}

func (*InstanceCredentialsProvider) Resolve

func (p *InstanceCredentialsProvider) Resolve() (auth.Credential, error)

type ProfileProvider

type ProfileProvider struct {
	Profile string
}

func (*ProfileProvider) Resolve

func (p *ProfileProvider) Resolve() (auth.Credential, error)

Resolve implements the Provider interface when credential type is rsa_key_pair, the content of private_key file must be able to be parsed directly into the required string that NewRsaKeyPairCredential function needed

type Provider

type Provider interface {
	Resolve() (auth.Credential, error)
}

When you want to customize the provider, you only need to implement the method of the interface.

func NewEnvProvider

func NewEnvProvider() Provider

func NewInstanceCredentialsProvider

func NewInstanceCredentialsProvider() Provider

func NewProfileProvider

func NewProfileProvider(name ...string) Provider

NewProfileProvider receive zero or more parameters, when length of name is 0, the value of field Profile will be "default", and when there are multiple inputs, the function will take the first one and discard the other values.

func NewProviderChain

func NewProviderChain(providers []Provider) Provider

type ProviderChain

type ProviderChain struct {
	Providers []Provider
}

func (*ProviderChain) Resolve

func (p *ProviderChain) Resolve() (auth.Credential, error)
