Deployment on Linode
You can find the StackScript by searching for "s3b" or "saltcorn" or using the direct link: https://cloud.linode.com/stackscripts/932041.
The installation takes a couple of minutes, so be sure to give your Linode instance enough time to finish all the work (in my tests it took up to 5 minutes). You know when its done by checking http:// , where you will see the SaltCorn setup wizard.
If you'd like to run your instance with TLS encryption (HTTPS), you can run the setup-reverse-proxy script (link).
