Heroku Commands

There are many Heroku commands, and we’ll barely scratch the surface in this book. Let’s take a minute to show just one of them by renaming the application as follows:

Don’t use this name yourself; it’s already taken by me! In fact, you probably shouldn’t bother with this step right now; using the default address supplied by Herolu

Figure 1.11 The beautiful interface at Heroku.
 

But if you do want to rename your application, you can arrange for it to be reasonably secure by using a random or obscure subdomain, such as the following:

With a random subdomain like this, someone could visit your site only if you gave him or her the address. (By the way, as a preview of Ruby’s compact awesomeness, here’s the code I used to generate the random subdomains:

Pretty sweet.)

    In addition to supporting subdomains, Heroku also supports custom domains. (In fact, the Ruby on Rails Tutorial site lives at Heroku; if you’re reading this book online, you’re looking at a Heroku-hosted site right now!) See the Heroku documentation for more information about custom domains and other Heroku topics.
