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


      This section is empty.

        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

        func Get() (*Bootstrap, error)

          Get is shorthand for `GetFromEnv(environ.System())`.

          func GetFromEnv

          func GetFromEnv(env environ.Env) (*Bootstrap, error)

            GetFromEnv loads a Bootstrap instance from the given 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

            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.
