07/10/2008: Using SCP with Capistrano
t took me several hours to find out how to send a file to my remote computer via 
scp using Capistrano. It's actually quite easy.
There is a method called upload which has a via option. Here is an example of its use:
upload("products.txt", "/home/medined", :via => :scp)
If you need to change the files name, you can also specify it in the second parameter. For example,
upload("products.txt", "/home/medined/products_new.txt", :via => :scp)07/09/2008: Capistrano, ElasticFox & EC2
What a nice combination of tools! I just installed Capistrano and created a capfile. From then on, I could run commands across all my virtual istances in one shot. This setup took just minutes. The only change that I made to my existing instances was to add a capistrano userid. My capfile looks like this:
role :files,
"capistrano@ec2-75-101-225-105.compute-1.amazonaws.com",
"capistrano@ec2-67-202-59-118.compute-1.amazonaws.com"
namespace :files do
desc "Show free disk space"
task :show_free_space, :roles => :files do
run "df -h /"
end
end
The best thing of all? No XML configuration!
