Types

type ClaimHolder 

type ClaimHolder interface {
	GetClaim(key string) (interface{}, error)
}

ClaimHolder is implemented by any token interface that provides access to the security claims embedded in the token.

type ConfigurationProviderWithClaimAccess 

type ConfigurationProviderWithClaimAccess interface {
	common.ConfigurationProvider
	ClaimHolder
}

ConfigurationProviderWithClaimAccess mixes in a method to access the claims held on the underlying security token

func ResourcePrincipalConfigurationProvider 

func ResourcePrincipalConfigurationProvider() (ConfigurationProviderWithClaimAccess, error)

ResourcePrincipalConfigurationProvider returns a resource principal configuration provider using well known environment variables to look up token information. The environment variables can either paths or contain the material value of the keys. However in the case of the keys and tokens paths and values can not be mixed

func ResourcePrincipalConfigurationProviderWithPathProvider 

func ResourcePrincipalConfigurationProviderWithPathProvider(pathProvider PathProvider) (ConfigurationProviderWithClaimAccess, error)

ResourcePrincipalConfigurationProviderWithPathProvider returns a resource principal configuration provider using path provider.

type DefaultRptPathProvider 

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

DefaultRptPathProvider path provider makes sure the behavior happens with the correct fallback.

For the path, Use the contents of the OCI_RESOURCE_PRINCIPAL_RPT_PATH environment variable, if set. Otherwise, use the current path: "/20180711/resourcePrincipalToken/{id}"

For the resource id, Use the contents of the OCI_RESOURCE_PRINCIPAL_RPT_ID environment variable, if set. Otherwise, use IMDS to get the instance id

This path provider is used when the caller doesn't provide a specific path provider to the resource principals signer

func (DefaultRptPathProvider) Path 

func (pp DefaultRptPathProvider) Path() (*string, error)

Path returns the resource principal token path

func (DefaultRptPathProvider) ResourceID 

func (pp DefaultRptPathProvider) ResourceID() (*string, error)

ResourceID returns the resource associated with the resource principal

type EnvRptPathProvider 

type EnvRptPathProvider struct{}

EnvRptPathProvider sets the path and resource ID from environment variables

func (EnvRptPathProvider) Path 

func (pp EnvRptPathProvider) Path() (*string, error)

Path returns the resource principal token path

func (EnvRptPathProvider) ResourceID 

func (pp EnvRptPathProvider) ResourceID() (*string, error)

ResourceID returns the resource associated with the resource principal

type ImdsRptPathProvider 

type ImdsRptPathProvider struct{}

ImdsRptPathProvider sets the path from a default value and the resource ID from instance metadata

func (ImdsRptPathProvider) Path 

func (pp ImdsRptPathProvider) Path() (*string, error)

Path returns the resource principal token path

func (ImdsRptPathProvider) ResourceID 

func (pp ImdsRptPathProvider) ResourceID() (*string, error)

ResourceID returns the resource associated with the resource principal

type PathProvider 

type PathProvider interface {
	Path() (*string, error)
	ResourceID() (*string, error)
}

PathProvider is an interface that returns path and resource ID

type StringRptPathProvider 

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

StringRptPathProvider is a simple path provider that takes a string and returns it

func (StringRptPathProvider) Path 

func (pp StringRptPathProvider) Path() (*string, error)

Path returns the resource principal token path

func (StringRptPathProvider) ResourceID 

func (pp StringRptPathProvider) ResourceID() (*string, error)

ResourceID returns the resource associated with the resource principal

type Token 

type Token struct {
	Token string `mandatory:"true" json:"token,omitempty"`
}

Token token

type X509FederationDetails 

type X509FederationDetails struct {
	Certificate              string   `mandatory:"true" json:"certificate,omitempty"`
	PublicKey                string   `mandatory:"true" json:"publicKey,omitempty"`
	IntermediateCertificates []string `mandatory:"false" json:"intermediateCertificates,omitempty"`
	Purpose                  string   `mandatory:"true" json:"purpose,omitempty"`
