I already had python installed on my Mac so the steps were...
- sudo easy_install dotcloud
- dotcloud create leotest
- dotcloud deploy --type perl leotest.www
- cd plack-example/multiple_roots/
- dotcloud push leotest.www ./
- open http://www.leotest.dotcloud.com/
My multiple_roots test is a slightly contrived configuration, using Plack::App::TemplateToolkit with multiple roots for static and dynamic content, this is configured in the app.psgi. I had put it together when I was developing Plack::App::TemplateToolkit so thought it was a good example to test.
The only issue I had was that the default configuration of DotCloud serves anything in ^static directly through nginx so I had to rename my directories to get it to work. Previously I didn't have a Makefile.PL as this had just been for testing, I created one, so the dependencies could be installed.
You can see the final (although visually dull!) result at http://www.leotest.dotcloud.com/.
I can see myself using this service a lot in the near future.
