Functions

func MaxSVIDTTL added in v1.0.1

func MaxSVIDTTL() time.Duration

MaxSVIDTTL returns the maximum SVID lifetime that can be guaranteed to not be cut artificially short by a scheduled rotation.

func (*Manager) PublishJWTKey added in v0.10.0

func (m *Manager) PublishJWTKey(ctx context.Context, jwtKey *common.PublicKey) ([]*common.PublicKey, error)

PublishJWTKey publishes the passed JWK to the upstream server using the configured UpstreamAuthority plugin, then appends to the bundle the JWKs returned by the upstream server, and finally it returns the updated list of JWT keys contained in the bundle.

The following cases may arise when calling this function:

- The UpstreamAuthority plugin doesn't implement PublishJWTKey, in which case we receive an Unimplemented error from the upstream server, and hence we log a one time warning about this, append the passed JWK to the bundle, and return the updated list of JWT keys.

- The UpstreamAuthority plugin returned an error, then we return the error.

- There is no UpstreamAuthority plugin configured, then assumes we are the root server and just appends the passed JWK to the bundle and returns the updated list of JWT keys.
