Today I updated several of my deployments to capistrano 2.1.0. This is a great piece of software. I primarily use it for deployment of complicated PHP Applications and some systems administration tasks. It's a huge time saver and the latest versions are really nice. The one command, "cap deploy:rollback" is worth it all. Here's the thread with announcement and feature run down:
Here is the default commands output from a fresh application capify for built in commands:
> cap -Tv
cap deploy # Deploys your project.
cap deploy:check # Test deployment dependencies.
cap deploy:cleanup # Clean up old releases.
cap deploy:cold # Deploys and starts a `cold' application.
cap deploy:finalize_update # [internal] Touches up the released code.
cap deploy:migrate # Run the migrate rake task.
cap deploy:migrations # Deploy and run pending migrations.
cap deploy:pending # Displays the commits since your last deploy.
cap deploy:pending:diff # Displays the `diff' since your last deploy.
cap deploy:restart # Restarts your application.
cap deploy:rollback # Rolls back to a previous version and restarts.
cap deploy:rollback_code # Rolls back to the previously deployed version.
cap deploy:setup # Prepares one or more servers for deployment.
cap deploy:start # Start the application servers.
cap deploy:stop # Stop the application servers.
cap deploy:symlink # Updates the symlink to the most recently deploye...
cap deploy:update # Copies your project and updates the symlink.
cap deploy:update_code # Copies your project to the remote servers.
cap deploy:upload # Copy files to the currently deployed version.
cap deploy:web:disable # Present a maintenance page to visitors.
cap deploy:web:enable # Makes the application web-accessible again.
cap invoke # Invoke a single command on the remote servers.
cap shell # Begin an interactive Capistrano session.
Capistrano takes a little getting used to for some but once you go there, you'll not likely want to go back. It's a great tool and I'm very thankful for the work the Jamis Buck has done on this project.
Like I said, I use this mostly for PHP projects lately, but if you are doing any Rails work you'd be nuts not to be using capistrano in one form or another.
