This tutorial will focus on using Capistrano to deploy a Rails application from a Subversion repository. It will be targeted at beginners (so if you already have experience with Capistrano, you might not find much value here). Attendees will be given temporary shell access to a server, and a simple Rails application will be provided. During the course of the tutorial, attendees will configure and deploy the Rails application.

If there is sufficient interest, and this format of presentation works well enough, I may offer subsequent sessions on more advanced topics, including (but not limited to) deployment using Git, non-Rails deployment, and non-deployment uses of Capistrano.

What version(s) of Capistrano will be covered?

This tutorial will only cover the most recent version of Capistrano (2.4.3, as of this writing). You do not need to have it preinstalled, as the tutorial will include instruction on installation if needed.

Older versions of Capistrano will not be covered, but if you have specific questions about an older version of Capistrano, you may ask them during the course of the tutorial.

Why Campfire (instead of e.g. IRC)?

For one thing, Campfire lets you easily paste images and code into the stream of the chat. This lets people follow along without having to jump to external links, potentially losing the context and the flow of the tutorial.

For another thing, Campfire provides transcripts. This means that I can easily email attendees a transcript of the session when the session is finished. (If things go well, and if there is enough interest, I may even offer the transcript for sale later, for a few dollars, to people who were unable to attend.)

If the session were very large (40, 50, or more people) Campfire might not be as good a fit for what I have in mind. But for a group of 10, it’s just about perfect.

Why only 10 people?

This session is just an experiment, to see how well this venue can work for teaching people how to use Capistrano. If it works well, I may experiment with larger groups later. For now, though, ten seems about right for a tutorial session. More than that and I think it would get difficult to give each attendee sufficient attention. I fully intend for these to be hands-on opportunities, where attendees will actually follow along and deploy an application.

Why $10, instead of free, or $100?

As mentioned above, this is just an experiment, not a money-making opportunity (yet!). If there is sufficient demand, subsequent sessions may cost more. The $10/seat is mostly just minimal compensation for the time I'm putting into organizing the session and creating the curriculum.

Also, if this initial experiment were free, the danger would be people signing up without commitment. By requiring people to pay for the privilege of attending, they are more likely to show up, and less likely to be frivolous or merely casually interested.

Why Subversion instead of Git, or CVS, etc.?

Because most Rails devs are still using Subversion. Besides which, once you can deploy from subversion, switching SCM’s isn’t that much of a jump. If there’s enough interest, I may offer another session sometime on Git-based deployment.

What should I expect if I sign up?

Once you sign up and your payment is received, you’ll receive an email with (among other things) a URL to a web page. This web page will initially just have the tutorial’s date and time on it, along with a list of software you should already have installed and configured on your server before the tutorial begins (including Ruby, Subversion, etc.).

A couple of hours before the session starts it will be updated with a URL to the Campfire room, as well as your login credentials to the server, and the location of the Subversion repository hosting the Rails application.

You may sign into the Campfire room any time after the URL is available. The session will start at the indicated time, with a few minutes spent on introductions and waiting for stragglers. The tutorial will then begin and will run for approximately two hours.

Once the tutorial ends, your access to the Campfire chat room and the tutorial server will be terminated. A transcript of the tutorial will be emailed to you.

For people who were unable to attend, the transcript may be made available for a small fee (probably just a few dollars for this first tutorial).
