Deploy Drupal with
Capistrano
and live to tell

“A life without philosophy Capistrano is
not worth living”
--Socrates

The plan
• Throw away what we don’t need
• Keep it simple
• ???
• Profit!

Standard stuff
“non ragioniam di lor, ma guarda e passa”
1 load 'deploy' if respond_to?(:namespace) # cap2 differentiator
2
3 # You should probably configure these
4 set :user, \"drupal\"
5 set :password, \"supersecret\"
6 set :application, \"my.application.name\"
7
8 # The default should be ok
9 set :deploy_to, \"/var/apps/#{application}\"
10
11 # SCM Stuff configure to taste, just remember the repository
12 set :repository, \"git@github.com:intinig/app.git\"
13 set :scm, :git
14 set :branch, \"master\"
15 set :repository_cache, \"git_master\"
16 set :deploy_via, :remote_cache
17 set :scm_verbose, true
18
19 # Single server setup
20 role :web, \"danton.mikamai.com:8888\", :primary => true

Callbacks
The Juice

Overriding
Who’s your daddy?
85 namespace :deploy do
86 task :finalize_update, :except => { :no_release => true } do
87 sudo \"chmod ‐R g+w #{latest_release}\" if fetch(:group_writable,
true)
88 end
89
90 task :cold do
91 update
92 start
93 end
94
95 task :restart do
96 end
97
98 task :start do
99 end
100 end

The (long) Drupal namespace
48 namespace :drupal do
49 task :setup, :except => { :no_release => true } do
50 sudo \"mkdir ‐p #{shared_path}/files\"
51 sudo \"chown ‐R #{user}:#{user} #{deploy_to}\"
52 end
53
54 task :symlink, :except => { :no_release => true } do
55 sudo \"ln ‐s #{shared_path}/files #{latest_release}\"
56 end
57
58 namespace :configure do
59 task :production do
60 sudo \"cd #{latest_release}/sites/default; cp settings.production.php settings.php\"
61 end
62
63 task :development do
64 sudo \"cd #{latest_release}/sites/default; cp settings.development.php settings.php\"
65 end
66 end

Still the (long) Drupal namespace
68 namespace :db do
69 namespace :dump do
70 task :development do
71 raise RuntimeError.new(\"failed dump\") unless system ...
72 end
73 end
74
75 namespace :import do
76 task :production do
77 ENV[\"FILES\"] = \"dump.sql\"
78 deploy::upload
79 run \"mysql ‐u #{db_user} ‐‐password=#{db_password} ...\"
80 end
81 end
82 end
83 end

Last, but not least...

How we do it in
Mikamai
102 namespace :mikamai do
103
104 namespace :production do
105 task :symlink, :except => { :no_release => true } do
106 sudo \"rm ‐rf /var/www/#{application}\"
107 sudo \"ln ‐s #{latest_release} /var/www/#{application}\"
108 end
109 end
110
111 namespace :permissions do
112 task :fix, :except => { :no_release => true } do
113 sudo \"chown ‐R www‐data:www‐data #{latest_release}\"
114 end
115 end
116
117 end
