Written in Go this is a clone of the AWS SQS/SNS systems. This system is designed to emulate SQS and SNS in a local environment so developers can test their interfaces without having to connect to 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.

All SNS/SQS APIs have been implemented except:

• The full capabilities for Get and Set QueueAttributes. At the moment you can only Get ALL the attributes.

Here is a list of the APIs:

• ListQueues
• CreateQueue
• GetQueueAttributes (Always returns all attributes - unsupporterd arttributes are mocked)
• GetQueueUrl
• SendMessage
• SendMessageBatch
• ReceiveMessage
• DeleteMessage
• DeleteMessageBatch
• PurgeQueue
• Delete Queue
• ChangeMessageVisibility
• ChangeMessageVisibilityBatch
• ListDeadLetterSourceQueues
• ListQueueTags
• RemovePermission
• SetQueueAttributes (Only supported attributes are set - see Supported Queue Attributes)
• TagQueue
• UntagQueue

• VisibilityTimeout
• ReceiveMessageWaitTimeSeconds
• RedrivePolicy

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

• Read config file
• -config flag to read a specific configuration file (e.g.: -config=myconfig.yaml)
• a command line argument to determine the environment to use in the config file (e.e.: Dev)
• IN the config file you can create Queues, Topic and Subscription see the example config file in the conf directory

go get github.com/p4tin/goaws/...

Build
    cd to GoAws directory
    go build -o goaws app/cmd/goaws.go  (The goaws executable should be in the currect directory, move it somewhere in your $PATH)

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)

Get it
    docker pull pafortin/goaws

run
    docker run -d --name goaws -p 4100:4100 pafortin/goaws

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.
