Yosuke Tomita

2. I’ll Talk about
how I feel about using chef,
how we use chef.
(not what is chef,
not why start using chef)
-> Derek will talk the second part
in Devops Day, 9/28

3. Chef and it’s recipe
connects many things….

11. ● Dev - Ops
● Production - Local
● English - Japanese

12. Local
Production

13. Develop Flow (for new application)
1. Develop in local.
2. Create recipe.
3. Test on QA env, both appication and recipe.
4. Deploy to Production using chef.
5. Make it work in local env(Vagrant).

14. Production
Knife solo
nodes/hoge1.fuga.com.json
{ "run_list": [
"role[api]"
],
"environment": "prod",
"n_fqdn": "hoge1.fuga.com",
"server_name": "api-live"
}
roles/api.rb
run_list(
"role[base]",
"recipe[nginx]",
"recipe[python]",
"recipe[repos::api]",
"recipe[monit]",
"recipe[monit::nginx]",
"recipe[monit::api]"
)
Local(Vagrant)
vagrant-omnibus
Vagrantfile
config.vm.provision :chef_solo do |chef|
chef.add_recipe "nginx"
chef.add_recipe "php_pack"
chef.add_recipe "base::git"
chef.add_recipe "repos::dev_repos"
chef.add_recipe "python"
chef.add_recipe "repos::api"
end

15. Knife solo
knife solo cook ubuntu@hoge1.fuga.com
&&
knife solo cook ubuntu@hoge2.fuga.com
daidokoro -> project-name
nodes -> server information
roles -> define role (web server, db etc..)
cookbooks -> recipes
data_bags -> store password etc..

16. nodes
nodes/hoge1.fuga.com.json
{ "run_list": [
"role[api]"
],
"environment": "prod",
"n_fqdn": "hoge1.fuga.com",
"server_name": "hoge1"
}

17. roles
roles/api.rb
run_list(
"role[base]",
"recipe[nginx]",
"recipe[python]",
"recipe[repos::api]",
"recipe[monit]",
"recipe[monit::nginx]",
"recipe[monit::api]"
)

18. cookbooks
cookbooks/repos/api.rb
- install required module for application (apt-get)
- setting virtualenv and install required package
- add start/stop shell
- restart service

19. Vagrant omnibus
A Vagrant plugin that ensures the desired
version of Chef is installed
https://github.com/schisamo/vagrant-omnibus
don’t need to “knife solo prepare”
in Vagrantfile
config.vm.provision :chef_solo do |chef|
chef.add_recipe "redis"
chef.add_recipe "apache"
end

20. difference between local and prod
- port setting
use “template” resource
template "#{virtual_env}/bin/api_start.sh" do
source "api_start.sh.erb"
owner "deployer"
group "www-data"
mode 0655
variables({
:env => node['environment'],
:port => node['repos']['api_port']
})
end

21. difference between local and prod
- deploy
use “deploy” resource for prod,
use “git” resource for dev
deploy "/mnt#{node['repos']['home']}/#{project}" do
ssh_wrapper "/tmp/private_code/wrap-ssh4git.sh"
repo 'git@github.com:gengo/api'
branch "#{node['repos']['branch']}"
keep_releases 3
user "deployer"
group "www-data"
create_dirs_before_symlink []
symlink_before_migrate.clear
symlinks.clear
symlinks "bin" => "bin"
notifies :restart, "service[#{project}]"
end
http://docs.opscode.com/resource.html
git "#{node['repos']['home']}/#{project}" do
repository "git@github.com:gengo/api.git"
ssh_wrapper "/tmp/private_code/wrap-ssh4git.sh"
action :checkout
notifies :restart, "service[#{project}]"
end

24. 日本人はドキュメント作って、
忠実に実行することが得意だから、
Chef のようなツールが浸透しない
(らしい)
↓
Gengoは、、、、
+ 言葉の壁、、、

25. Can review the code if can’t hear well.
Can explain with code if can’t speak well.
No (less?) manual operation on a server.
<- When Running the same recipe in next release,
the change can be lost.
Infrastructure as code (for me)

26. Chef connects….
● Dev - Ops
● Production - Local
● English - Japanese
and more!!!
