aws.go - A simple AWS client for Go.

Install

$ go get github.com/bmizerany/aws.go

Use

// NOTE: This project is still a work in progress.  For those of you who
// see where I'm going with it and want to help, please do!

package main

import (
	"github.com/bmizerany/aws"
	"log"
)

// Assumes AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY are set in ENV.
func main() {
	v, err := aws.DescribeInstances()
	if err != nil {
		log.Fatal(err)
	}

	for _, r := range v.Reservations {
		for _, i := range r.Instances {
			log.Println("%s -> %s", i.DnsName, i.StateName)
		}
	}

	////
	// Custom (i.e. No sugar yet)

	r := aws.TemplateRequest // Make a copy of the template request

	// Set the Action parameter
	r.Add("Action", "DescribeKeyPairs")

	// Describe the response you expect using
	// http://weekly.golang.org/pkg/encoding/xml/#Unmarshal as a guide
	type DescribeKeyPairsResponse struct {
		aws.Header       // Holds the RequestId
		Keys       []Key `xml:"keySet>item"`
	}

	type Key struct {
		KeyName        string
		KeyFingerprint string
	}

	v := new(DescribeKeyPairsResponse)
	aws.Do(r, v)

	log.Printf("%v", v)
}

Change API/Creds

You can change the API and Credentials, used by the Sugar commands, by updating aws.TemplateRequest.

Running tests

NOTE: Most Unix/Linux systems will not log commands to history if they start with spaces; BEWARE if yours does not.

$ cd /path/to/repo
$ git config add aws.key <aws-key>
$ git config add aws.secret <aws-secret>
$ ./development.sh gotest // Does NOT create resources

or

$ <space><space> AWS_SECRET_ACCESS_KEY=<secret> AWS_ACCESS_KEY_ID=<key> gotest
