Functions

func With

func With(ctx context.Context, cfg *FulcioConfig) context.Context

Types

type FulcioConfig

type FulcioConfig struct {
	OIDCIssuers map[string]OIDCIssuer `json:"OIDCIssuers,omitempty"`

	// A meta issuer has a templated URL of the form:
	//   https://oidc.eks.*.amazonaws.com/id/*
	// Where * can match a single hostname or URI path parts
	// (in particular, no '.' or '/' are permitted, among
	// other special characters)  Some examples we want to match:
	// * https://oidc.eks.us-west-2.amazonaws.com/id/B02C93B6A2D30341AD01E1B6D48164CB
	// * https://container.googleapis.com/v1/projects/mattmoor-credit/locations/us-west1-b/clusters/tenant-cluster
	MetaIssuers map[string]OIDCIssuer `json:"MetaIssuers,omitempty"`
	// contains filtered or unexported fields
}

func FromContext

func FromContext(ctx context.Context) *FulcioConfig

func Load

func Load(configPath string) (*FulcioConfig, error)

Load a config from disk, or use defaults

func Read

func Read(b []byte) (*FulcioConfig, error)

Read parses the bytes of a config

func (*FulcioConfig) GetIssuer

func (fc *FulcioConfig) GetIssuer(issuerURL string) (OIDCIssuer, bool)

GetIssuer looks up the issuer configuration for an `issuerURL` coming from an incoming OIDC token. If no matching configuration is found, then it returns `false`.

func (*FulcioConfig) GetVerifier

func (fc *FulcioConfig) GetVerifier(issuerURL string) (*oidc.IDTokenVerifier, bool)

GetVerifier fetches a token verifier for the given `issuerURL` coming from an incoming OIDC token. If no matching configuration is found, then it returns `false`.

func (*FulcioConfig) ToIssuers

func (fc *FulcioConfig) ToIssuers() []*fulciogrpc.OIDCIssuer

ToIssuers returns a proto representation of the OIDC issuer configuration.

type IssuerType

type IssuerType string

type OIDCIssuer

type OIDCIssuer struct {
	// The expected issuer of an OIDC token
	IssuerURL string `json:"IssuerURL,omitempty"`
	// The expected client ID of the OIDC token
	ClientID string `json:"ClientID"`
	// Used to determine the subject of the certificate and if additional
	// certificate values are needed
	Type IssuerType `json:"Type"`
	// Optional, if the issuer is in a different claim in the OIDC token
	IssuerClaim string `json:"IssuerClaim,omitempty"`
	// The domain that must be present in the subject for 'uri' issuer types
	// Also used to create an email for 'username' issuer types
	SubjectDomain string `json:"SubjectDomain,omitempty"`
	// SPIFFETrustDomain specifies the trust domain that 'spiffe' issuer types
	// issue ID tokens for. Tokens with a different trust domain will be
	// rejected.
	SPIFFETrustDomain string `json:"SPIFFETrustDomain,omitempty"`
	// Optional, the challenge claim expected for the issuer
	// Set if using a custom issuer
	ChallengeClaim string `json:"ChallengeClaim,omitempty"`
