API

This is the REST API reference of hyperd based on The latest release.

1. Introduction

By default hyperd listens on unix:///var/run/hyper.sock and the client must have root access to interact with the daemon.
The current release does not support encrypted connections.
The Remote API uses an open schema model. In this model, unknown properties in incoming messages will be ignored. Client applications need to take this in consideration to ensure they will not break when talking to newer hyperd daemons.
Calling /info is the same as calling /${latest}/info
The API tends to be RESTful, but in a few exceptions, e.g. attach, pull, the HTTP connection is hijacked to transport stdout, stdin and stderr.

dockerfile - path within the build context to the Dockerfile
t          – repository name (and optionally a tag) to be applied to the resulting image in case of success
