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 SNS 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

Build and Run (Standalone)

Build
    cd to GoAws directory
    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)

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"

    {

    }

• aws --endpoint-url http://localhost:4100 sqs receive-message --queue-url http://localhost:4100/test1

    {

            }
        ]
    }

• aws --endpoint-url http://localhost:4100 sqs delete-message --queue-url http://localhost:4100/test1 --receipt-handle 66a1b4f5-cecf-473e-92b6-810156d41bbe#f1fc455c-698e-442e-9747-f415bee5b461

    No output

• aws --endpoint-url http://localhost:4100 sqs receive-message --queue-url http://localhost:4100/test1

    No output (No messages in Q)

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

    No output

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

    No output (There are no Queues left)

(Topics are created hard coded (until create-topic is implemented)

• aws --endpoint-url http://localhost:4100 sns list-topics

    {
        "Topics": [
            {
                "TopicArn": "arn:aws:sns:local:000000000000:topic1"
            }, 
            {
                "TopicArn": "arn:aws:sns:local:000000000000:topic2"
            }
