# Microsoft Azure SDK for Go
This project provides various Go packages to perform operations
on Microsoft Azure REST APIs.
[![GoDoc](https://godoc.org/github.com/Azure/azure-sdk-for-go?status.svg)](https://godoc.org/github.com/Azure/azure-sdk-for-go) [![Build Status](https://travis-ci.org/Azure/azure-sdk-for-go.svg?branch=master)](https://travis-ci.org/Azure/azure-sdk-for-go)
See list of implemented API clients [here](http://godoc.org/github.com/Azure/azure-sdk-for-go).
> **NOTE:** This repository is under heavy ongoing development and
is likely to break over time. We currently do not have any releases
yet. If you are planning to use the repository, please consider vendoring
the packages in your project and update them when a stable tag is out.
# Installation
go get -d github.com/Azure/azure-sdk-for-go/management
# Usage
Read Godoc of the repository at: http://godoc.org/github.com/Azure/azure-sdk-for-go/
The client currently supports authentication to the Service Management
API with certificates or Azure `.publishSettings` file. You can
download the `.publishSettings` file for your subscriptions
[here](https://manage.windowsazure.com/publishsettings).
### Example: Creating a Linux Virtual Machine
```go
package main
import (
"encoding/base64"
"fmt"
"github.com/Azure/azure-sdk-for-go/management"
"github.com/Azure/azure-sdk-for-go/management/hostedservice"
"github.com/Azure/azure-sdk-for-go/management/virtualmachine"
"github.com/Azure/azure-sdk-for-go/management/vmutils"
)
func main() {
dnsName := "test-vm-from-go"
storageAccount := "mystorageaccount"
location := "West US"
vmSize := "Small"
vmImage := "b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu-14_04-LTS-amd64-server-20140724-en-us-30GB"
userName := "testuser"
userPassword := "Test123"
client, err := management.ClientFromPublishSettingsFile("path/to/downloaded.publishsettings", "")
if err != nil {
panic(err)
}
// create hosted service
if err := hostedservice.NewClient(client).CreateHostedService(hostedservice.CreateHostedServiceParameters{
ServiceName: dnsName,
Location: location,
Label: base64.StdEncoding.EncodeToString([]byte(dnsName))}); err != nil {
panic(err)
}
// create virtual machine
role := vmutils.NewVMConfiguration(dnsName, vmSize)
vmutils.ConfigureDeploymentFromPlatformImage(
&role,
vmImage,
fmt.Sprintf("http://%s.blob.core.windows.net/sdktest/%s.vhd", storageAccount, dnsName),
"")
vmutils.ConfigureForLinux(&role, dnsName, userName, userPassword)
vmutils.ConfigureWithPublicSSH(&role)
operationID, err := virtualmachine.NewClient(client).
CreateDeployment(role, dnsName, virtualmachine.CreateDeploymentOptions{})
if err != nil {
panic(err)
}
if err := client.WaitForOperation(operationID, nil); err != nil {
panic(err)
}
}

* `container`: Name of the root storage container in which all registry data will be stored. Must comply the storage container name [requirements][create-container-api].
* `realm`: (optional) Domain name suffix for the Storage Service API endpoint. Defaults to `core.windows.net`. For example realm for "Azure in China" would be `core.chinacloudapi.cn` and realm for "Azure Government" would be `core.usgovcloudapi.net`.
## Developing
To include this driver when building Docker Distribution, use the build tag
`include_azure`. Please see the [building documentation][building] for details.
