In this tutorial, we will be speaking about a “Swiftbox”. This is nothing more than our terminology for an Openstack installation that only needs and uses Swift and Keystone. The use and setup of this Swiftbox will be explained in this article.
The reason why someone might want a stripped-down OpenStack installation with only Swift and Keystone running, is that it allows easy testing of Swift services. A Swiftbox can be used to try understanding how object storage works. Also, having an independent object storage, is a good perk: it allows testing or running various different projects, with only one Swiftbox to be configured for everything.
A use case for this standalone Swift installation is to reproduce an isolated and potentially local environment to test applications that need or want to use Swift as their object storage backend. This can prove useful to experiment with the technology as well as to debug or exercise existing applications.
For the simplified nature of the Swift installation here described (everything runs inside a VM and not over a cluster of nodes!), this procedure should not be considered to run Swift for anything else than a stubby backend for a testing environment.
The main steps to set up a Swiftbox are:
- Creating and configuring a VM (we will use Vagrant and run a Ubuntu Server 14.04 box)
- Configuring Devstack
- Configuring a Keystone endpoint for Swift
- Testing Swift
- Some troubleshooting
