sshkit-interactive

SSHKit::Interactive

An SSHKit backend that allows you to execute interactive commands on your servers. Remote commands that you might want to use this for:

• A Rails console
• A text editor
• less
• etc.

Installation

Add this line to your application's Gemfile:

gem 'sshkit-interactive'

And then execute:

$ bundle

If you're using Capistrano, add the following to your Capfile:

require 'sshkit/interactive'

Usage

Running interactive commands will make a system call to ssh under the hood.

DSL

Using the DSL, simply put the command within the run_interactively block. In Capistrano, it might look something like this:

namespace :rails do
  desc "Run Rails console"
  task :console do
    run_interactively primary(:app) do
      execute(:rails, :console)
    end
  end
end

It is also possible to set directory and user the Capistrano way:

namespace :rails do
  desc "Run Rails console"
  task :console do
    run_interactively primary(:app) do
      within current_path do
        as user: :foobar do
          execute(:rails, :console)
        end
      end
    end
  end
end

And it is possible to set the shell to be used:

namespace :foo do
  task :bar do
    run_interactively primary(:app), shell: '/bin/bash' do
      ...
    end
  end
end

### Manually setting the backend

Use the [interactive backend](lib/sshkit/interactive/backend.rb) and execute commands as normal:

```ruby
SSHKit.config.backend = SSHKit::Interactive::Backend
hosts = %w{my.server.com}
on hosts do |host|
  execute(:vim)
end
