Rails-5 application deploy configuration using puma and nginx.

• Optional configuration of production and staging environments in same server.
• Embedded Nginx configuration.
• Embedded Puma init script and puma configuration.
• Log rotation.

Requires following gems.

gem 'puma'
group :development do
  gem 'capistrano'
  gem 'capistrano-bundler'
  gem 'capistrano-rails'
  gem 'capistrano-rails-console'
  gem 'capistrano-rbenv'
end

• Copy following files in your application root maintaining the structure:

.
├── Capfile
├── config
│  ├── deploy
│  │  ├── shared
│  │  │  ├── application.yml.template.erb
│  │  │  ├── database.yml.template.erb
│  │  │  ├── log_rotation.erb
│  │  │  ├── nginx.conf.erb
│  │  │  ├── puma.rb.erb
│  │  │  ├── puma_init.sh.erb
│  │  │  ├── secrets.yml.template.erb
│  │  ├── production.rb
│  │  └── staging.rb
│  └── deploy.rb
└── lib
   └── capistrano
      ├── substitute_strings.rb
      ├── tasks
      │  ├── check_revision.cap
      │  ├── compile_assets_locally.cap
      │  ├── db.cap
      │  ├── logs.cap
      │  ├── monit.cap
      │  ├── nginx.cap
      │  ├── puma.cap
      │  ├── push_deploy_tag.cap
      │  ├── run_tests.cap
      │  └── setup_config.cap
      └── template.rb

• Put rails project's git url under :repo_url in 'config/deploy.rb' file.

Example:

#config/deploy.rb
set :repo_url, '[email protected]:user/repo.git'

• Change application name under :application in 'config/deploy.rb' file.

Example:

#config/deploy.rb
set :application, 'demo_application'

• Define servers in 'config/deploy/production.rb' and 'config/deploy/staging.rb'

Example:

server '192.168.33.10', user: fetch(:deploy_user).to_s, roles: %w(app db), primary: true
server '192.168.33.11', user: fetch(:deploy_user).to_s, roles: %w(app), primary: true
server '192.168.33.12', user: fetch(:deploy_user).to_s, roles: %w(app), primary: true

• Set server name in 'config/deploy/production.rb' and 'config/deploy/staging.rb'

  Example:

# config/deploy/production.rb
set :server_names, {
  '192.168.33.10': '192.168.33.10 node0.server',
  '192.168.33.11': '192.168.33.11 node1.server',
  '192.168.33.12': '192.168.33.12 node2.server',
}

• Set certificate and key path in 'config/deploy/production.rb' and 'config/deploy/staging.rb'g

set :nginx_certificate_path, "#{shared_path}/certificates/#{fetch(:stage)}.crt"
set :nginx_key_path, "#{shared_path}/certificates/#{fetch(:stage)}.key"

For different certificate and key name in different server

set :nginx_certificate_paths, {
  '192.168.33.10': "/etc/certificates/192_168_33_10.crt",
  '192.168.33.11': "/etc/certificates/192_168_33_11.crt",
  '192.168.33.12': "/etc/certificates/192_168_33_12.crt",
}
set :nginx_key_paths, {
  '192.168.33.10': "/etc/certificates/192_168_33_10.key",
  '192.168.33.11': "/etc/certificates/192_168_33_11.key",
  '192.168.33.12': "/etc/certificates/192_168_33_12.key",
}

Note: configuration key name changes from *_path to *_paths
