Variables

var ErrNotBootstrapped = errors.New("not bootstrapped")

ErrNotBootstrapped is returned by Get when the current process is not bootstrapped.

type Bootstrap Uses

type Bootstrap struct {
    // CoordinatorHost is the name of the upstream Coordinator host.
    //
    // This is just the host name ("example.appspot.com"), not a full URL.
    //
    // If this instance is not configured using a production Coordinator Output,
    // this will be empty.
    CoordinatorHost string

    // Project is the Butler instance project name.
    Project types.ProjectName
    // Prefix is the Butler instance prefix.
    Prefix types.StreamName
    // Namespace is prefix for stream names.
    Namespace types.StreamName

    // Client is the streamclient for this instance, or nil if the Butler has no
    // streamserver.
    Client *streamclient.Client
}

Bootstrap contains information about the configured bootstrap environment.

The bootstrap environment is loaded by probing the local application environment for variables emitted by a bootstrapping Butler.

func Get Uses

func Get() (*Bootstrap, error)

Get loads a Bootstrap instance from the environment. It will return an error if the bootstrap data is invalid, and will return ErrNotBootstrapped if the current process is not bootstrapped.

func (*Bootstrap) GetViewerURL Uses

func (bs *Bootstrap) GetViewerURL(paths ...types.StreamPath) (string, error)

GetViewerURL returns a log stream viewer URL to the aggregate set of supplied stream paths.

If both the Project and CoordinatorHost values are not populated, an error will be returned.
