Gem in a Box Secure is a very basic branch of the awesome Gem in a box - a simple sinatra app to allow you to host your own in-house gems. The main difference here is the secure flavor provides configurable forced SSL and HTTP basic auth.
gem install geminabox-secure
Create a config.ru as follows:
require "rubygems"
require "geminabox-secure"
GeminaboxSecure.data = "/var/geminabox-data" # …or wherever
GeminaboxSecure.force_ssl = true #if you want SSL redirects enabled
run GeminaboxSecure
Set environment variables for your username and password: GEMBOX_USER and GEMBOX_PASSWORD, respectively. Gem in a Box Secure defaults to "admin" and "s3cret" respectively if these are not set.
Set up your SSL certificates for your server of choice.
And finally, hook up the config.ru as you normally would (passenger, thin, unicorn, whatever floats your boat).
gem install geminabox-secure
gem inaboxsecure pkg/my-awesome-gem-1.0.gem
Simples!
