This project uses libcarina and andlabs/ui to create a simple GUI for managing clusters on Carina by Rackspace. The GUI looks like this:

You can download the binary from the release page.

The GUI requires an API endpoint, your Rackspace username, and your API key (available in your user settings). It will try to use the environment variables CARINA_API_ENDPOINT, CARINA_USERNAME, and CARINA_APIKEY to pre-populate these fields.

See andlabs/ui for more specific requirements for your platform, but on OSX the main thing you need is XCODE and Go 1.5. Once you have thos, do this:

GOOS=darwin go build -a -installsuffix cgo -o carina-gui-darwin-amd64 .

Use chmod +x carina-gui-darwin-amd64 to make it executable.
