GoAws

Written in Go this is a clone of the AWS SQS/SNS systems. This system is designed to emulate SQS ans SNS in a local environment so developers can test their interfaces without having to connect the the AWS Cloud and possibly incurring the expense, or even worse actually write to production topics/queues by mistake. If you see any problems or would like to see a new feature, please open an issue here in github. As well, I will logon to Gitter so we can discuss your deployment issues or the weather.

Current SQS APIs implemented:

• ListQueues
• CreateQueue
• GetQueueAttributes (Always returns all attributes - depth and arn are set correctly others are mocked)
• GetQueueUrl
• SendMessage
• ReceiveMessage
• DeleteMessage
• PurgeQueue
• Delete Queue

Current SQS APIs implemented:

• ListTopics
• CreateTopic
• Subscribe (raw)
• ListSubscriptions
• Publish
• DeleteTopic
• Subscribe
• Unsubscribe
• ListSubscriptionsByTopic

Yaml Configuration Implemented

• Read config file
• Implement flag to chose configuration type
• Process Queue Creations
• Process Topic Creations
• Process Create Subscriptions

Note: The system does not authenticate or presently use https

Installation

go get github.com/p4tin/GoAws
go get github.com/tools/godep

Build and Run (Standalone)

Build
    cd to GoAws directory
    godep restore
    go build . 
    
Run
    ./goaws  (by default goaws listens on port 4100 but you can change it in the goaws.yaml file to another port of your choice)
    
Test

    go test -cover -race `go list ./... | grep -v /vendor/`

Run (Docker Version)

Get it
    docker pull pafortin/goaws
    
run
    docker run -d --name goaws -p 4100:4100 pafortin/goaws

Testing your installation

You can test that your installation is working correctly in one of two ways:

1. Usign the postman collection, use this link to import it. As well the Environment variable for the collection should be set as follows: URL = http://localhost:4100/.

2. by using the AWS cli tools (download link) here are some samples, you can refer to the aws cli tools docs for further information.

• aws --endpoint-url http://localhost:4100 sqs create-queue --queue-name test1

    {
        "QueueUrl": "http://localhost:4100/test1"
    }

• aws --endpoint-url http://localhost:4100 sqs list-queues

    {
        "QueueUrls": [
            "http://localhost:4100/test1"
        ]
    }

• aws --endpoint-url http://localhost:4100 sqs send-message --queue-url http://localhost:4100/test1 --message-body "this is a test of the GoAws Queue messaging"

        ]
    }
