Local

Production

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).

nodes

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

roles

roles/api.rb

run_list( "role[base]", "recipe[nginx]", "recipe[python]", "recipe[repos::api]", "recipe[monit]", "recipe[monit::nginx]", "recipe[monit::api]")

cookbooks

cookbooks/repos/api.rb

- install required module for application (apt-get)- setting virtualenv and install required package- add start/stop shell- restart service

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 Vagrantfileconfig.vm.provision :chef_solo do |chef|

chef.add_recipe "redis"chef.add_recipe "apache"

end

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

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

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

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、、、

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)

Chef connects….
