Capistranovelys - Keeping our recipes DRY

This gem includes every recipe/task that is in use in more than one project at Novelys.

capistranovelys has a dependency on recent versions of capistrano, meaning you can remove capistrano and capistrano-ext from your Gemfile, and replace it with :

gem "capistranovelys", '~> 2.0.1'

In your deploy.rb :

• remove `require "production_chain/capistrano" if you are using novelys/production_chain
• add require 'capistrano/novelys' (loads the core recipes)
• load recipes you need, eg: use_recipes :database, :rails2, :rbenv, :whenever. To be used BEFORE other loading of recipes such as deploy/assets, otherwise some hooks (such as the symlinks) will be executed too late.
  • You can use use_novelys_and [arg, ...]. It will load airbrake, rbenv, logs, stages, remote_commands, production_chain, and the recipes supplied as arguments. This will also use Novelys' configuration for user, deploy_to, and repository. Use use_novelys if you don't want/need anything else.
• You probably want to set user, deploy_to, and repository at the very least. Refer to core.rb to see which default values are set
• Make sure you don't have duplicates!

Common setup and options is done here. I suggest reading the file to go through all the details.

Basically, using core means you're using git, you're using rails, and you'll keep 5 releases.

This gem has a dependency on sushi. This allows you to do capistrano [stage] ssh.

Rails 3 & 4 commands.

• rails:console : open a rails console
• rails:secret_token:copy : copy the secret_token from your local file to the shared path
• rails:secret_token:symlink : symlink the secret_token.rb file from the shared path to the current path. Hooked after deploy:update_code

Rails 2 commands.

• rails:console : open a rails console
• rails:secret_token:copy : copy the session_store from your local file to the shared path
• rails:secret_token:symlink : symlink the session_store.rb file from the shared path to the current path. Hooked after deploy:update_code

Replacement with better defaults for stages:

• bundles two stages, staging and production, staging being the default`;
• those stages comes with default for branch and rails_env; staging can override branch at runtime (via cap -S branch=value);
• if no stages are specified, stages are defined and loaded by looking in config/deploy/*.rb

You should not require capistrano/ext/multistage.

• database:create : create the database
• database:seed : seed the database
• database:copy : copy the database.yml from your local file to the shared path
• database:symlink : symlink the database.yml file from the shared path to the current path. Hooked after deploy:update_code

• mongoid:copy : copy the mongoid.yml from your local file to the shared path
• mongoid:symlink : symlink the mongoid.yml file from the shared path to the current path. Hooked after deploy:update_code
• mongoid:index : create the indexes

• logs:tail : tail the logs of the rails app

Recipes usings rake tasks from novelys/production_chain. Will work only if the gem is present.

• db:dump_and_restore: restore the database from the server to your local env. Supply FILE=mongoid when using mongoid.
• assets:dump_and_restore: restore the assets from the public direction to your local env.

• remote:rake : Execute a rake task on the target (eg: cap remote:rake "assets:precompile")
• remote:command : Execute a shell command on the target (eg: cap remote:command ls)

• s3:copy : copy the amazon_s3.yml from your local file to the shared path
• s3:symlink : symlink the amazon_s3.yml file from the shared path to the current path. Hooked after deploy:update_code

deploy:start, deploy:stop, deploy:graceful_stop, deploy:reload, deploy:restart tasks for unicorn

deploy:start, deploy:stop, deploy:graceful_stop, deploy:reload, deploy:restart tasks for puma. Doesn't actually do anything except requiring "puma".

• airbrake:copy : copy the airbrake.rb from your local file to the shared path
• airbrake:symlink : symlink the airbrake.rb file from the shared path to the current path. Hooked after deploy:update_code

• thinking_sphinx:copy : copy the *.sphinx.conf from your local file to the shared path
• thinking_sphinx:symlink : symlink the *.sphinx.conf file from the shared path to the current path. Hooked after deploy:update_code
