capistranoをほんのちょっと動かしてみる④(namespace)

(3)ではひとつのタスクに複数の処理を記載した。 今回はnamespaceを使って処理を分割する。 namespaceはタスクが増えたときに固めて定義できる空間名みたい。

変更するファイルは下記。 ./config/develop/manage.rb

load './config/servers.rb'

namespace :exec do
        dir = "/root/test"

        desc "test"
        task :mkdir do

                on roles( :client ) do
                        execute "mkdir -p #{dir}"
                end
        end

        task :ls do
                on roles( :client ) do
                        execute "ls -ld #{dir}"
                end
        end
end

mkdirのタスクを実行してみる。(cap 環境 空間名:タスク名)
