Vassal

A Fake SQS server to aid in SQS development.

Installation

Vassal is released in 2 forms - a docker container and a packaged release.

Running via Docker

Installing & running Vassal via docker is the simplest option:

docker run -p 4567:4567 -d obmarg/vassal:0.2.1

Installing & Running from Release

To install a release:

• Download the relevant release from github releases.
• Untar it.
• Run the server in the background with bin/vassal start.

For example:

mkdir vassal
cd vassal
wget https://github.com/obmarg/vassal/releases/download/v0.2.1/vassal-0.2.1-osx.tar.gz
tar -xf vassal-0.2.1-osx.tar.gz
bin/vassal start

Configuration

By default, Vassal assumes that it will be accessed via localhost. If that is not the case, then you should provide the correct url in the URL environment variable.

Implemented Actions

• CreateQueue
• GetQueueUrl
• DeleteQueue
• SendMessage

Missing Features

Some of these may be implemented in the near future:

• Batch sends/changes/deletes

• Getting non-config queue attributes (other than ARN). ApproximateNumberOfMessages etc. are not supported.
• Authentication / permissions, or anything related.
• MD5 checksums.
• SenderId Attribute on messages.
• MessageRetentionPeriod is currently ignored.
