Capistrano get method - download files from server

Still looking if there is better way to do this (and I bet there it is :), but until I realize, add to top of deploy.rb:


# Get file remote_path from FIRST server targetted by
# the current task and transfer it to local machine as path, SFTP required
def actor.get(remote_path, path, options = {})
    execute_on_servers(options) do |servers|
      self.sessions[servers.first].sftp.connect do |tsftp|
        logger.info "Get #{remote_path} to #{path}" 
        tsftp.get_file remote_path, path
      end
    end
end

Sample recipe to get production log from server:


task :download_log, :roles => :web, :only => { :primary => true } do
get "#{deploy_to}/current/log/production.log",
     "log/production.log.web" //download server log
end

This is sweet. I use this for production logs and my database backup files

newer versions of cap have download, seems to work the same way…
1. Initiates a download from remote to local, asynchronously. This
2. method will return a new Net::SFTP::Operations::Download instance, and requires
3. that the event loop be run in order for the download to progress. See
4. Net::SFTP::Operations::Download for a full discussion of hos this method can be
5. used. #
6. download = sftp.download(”/remote/path”, ”/local/path”)
7. download.wait def download(remote, local, options={}, &block) Operations::Download.new(self, local, remote, options, &block) end
