Overview

Package juju provide utilities functions for interaction with Juju. It also provides a provisioner implementation for Juju.

In order to use the provisioner, just import tsuru's provision package and juju provision package. Then call provision.Get("juju") to get an instance of JujuProvisioner:

import (
    "github.com/globocom/tsuru/provision"
    _ "github.com/globocom/tsuru/provision/juju"
)
// ...
func main() {
    provisioner, err := provision.Get("juju")
    // Use provisioner.
}

Functions

func IsReachable

func IsReachable(unit provision.Unit) (bool, error)

isReachable returns true if the web application deploy in the unit is accessible via http in the port 80.

func Router

func Router() (router.Router, error)

Types

type JujuProvisioner

type JujuProvisioner struct {
	// contains filtered or unexported fields
}

JujuProvisioner is an implementation for the Provisioner interface. For more details on how a provisioner work, check the documentation of the provision package.

type Writer

type Writer struct {
	io.Writer
}

Writer is a custom writer that filters output from Juju.

It ignores all Juju logging and Python warnings.

func (*Writer) Write

func (w *Writer) Write(data []byte) (int, error)

Write writes data to the underlying writer, filtering the juju warnings.
