Now that I’m getting at the point that I can update the different rails apps regularly,
it’s about time to update my deployment process.
After every deploy I have to :
- Login to the host
- Navigate to app/current directory
- Run bundle
- Run rake assets:precompile
- Restart application server
Fuck this! Let’s update.
- Add capistrano gems to Gemfile
group :development do
gem 'capistrano','3.2.1'
gem 'capistrano-rvm', github: 'capistrano/rvm'
gem 'capistrano-rails'
gem 'capistrano-bundler'
end
- Require specific files in Capfile
# Load DSL and Setup Up Stages
require 'capistrano/setup'
# Includes default deployment tasks
require 'capistrano/rvm'
require 'capistrano/deploy'
require 'capistrano/rails'
require 'capistrano/rails/migrations'
# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
# config valid only for Capistrano 3.1
lock '3.2.1'
set :application, 'shops'
set :repo_url, 'git@dev.suwappu.net:suwappu/shops.git'
set :deploy_to, '/nfs/apps/shops_production'
set :ssh_options, {
forward_agent: true
}
set :pty, true
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle
public/system}
# Default value for default_env is {}
# set :default_env, { path: "/opt/rbenv/shims:$PATH" }
set :rvm_type, :user # Defaults to: :auto
set :rvm_ruby_version, 'rbx-2.2.10' # Defaults to: 'default'
set :rvm_custom_path, '/usr/local/rvm' # only needed if not detected
stage = "production"
shared_path = "/nfs/apps/shops_production/shared"
puma_sock = "unix://#{shared_path}/sockets/puma.sock"
puma_control = "unix://#{shared_path}/sockets/pumactl.sock"
puma_state = "#{shared_path}/sockets/puma.state"
puma_log = "#{shared_path}/log/puma-#{stage}.log"
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
# execute :touch, release_path.join('tmp/restart.txt')
execute 'sudo /etc/init.d/puma restart'
end
end
desc 'Resetting DB & seeding'
task :db_reset_and_seed do
on roles(:app) do
within "#{current_path}" do
with rails_env: :production do
execute :rake, "db:migrate:reset"
execute :rake, "db:seed"
end
end
end
end
after :publishing, :restart
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
end
end
end
Application server is not restarted yet.
I’ll give it some time to fix, but if it takes to long I’ll just leave it open.
It was because of the very weak bootscript for the application server.
Changed it to :
echo -n "Restarting Puma server for $APP..."
su - $USR -c "kill -s SIGTERM `cat $PID`"
rm /nfs/apps/shops_production/shared/tmp/pids/*
su - $USR -c "cd $APP/current ; bundle exec thin start -p 8080 -e $ENV -P $PID -d"
echo "[ Done ]"
After separating web and zmq-backend we’ll be using a different application server.
Then I’ll look to upgrade the application bootscript.
