Deploy process

[Nuno Brito]

Hello all, I am facing some issues on the deployment... by the way, Alchemy CMS is great, and I think your work is awesome... thank you :)

So, I need to run the following tasks so the capistrano can create the required shared folders for the shared assets:

• after "deploy:setup", "alchemy:shared_folders:create"
  
• after "deploy:finalize_update", "alchemy:shared_folders:symlink"
  

However it gives an error in the end of the deployment process:

• the task `alchemy:shared_folders:symlink' does not exist
  

Then I tried to add in the beggining of the deploy.rb file:

• require 'alchemy/capistrano'
  

but it gives the error as soon as I execute the cap:deploy:

• in `require': cannot load such file -- alchemy/capistrano (LoadError)
  

What am I doing wrong? Shouldn't the cap script load those alchemy files with the available functions?

Thank you for your help

Hi. 

Please use the new capistrano-alchemy Gem (https://github.com/AlchemyCMS/capistrano-alchemy) that supports latest Capistrano 3.x version. The build in Capistrano receipt is for Capistrano 2.x and will be removed soon. 

Best

Thomas

Hi tvdeyen,

I will try it.

However, how should I use my own deploy script and add just those lines?

What is the usual delpoy.rb file? I have some paperclip shared folders that I also need to create and symlink.

Is there any complete app deploy example I can look at?

Thank you for your help ;)

Hi. Capistrano is the go-to deploy solution for any kind of rails app. 

Please have a look at the official documentation.

Hi Thomas,

I changed to capistrano 3.1.0

I was able to make a first deploy with that... 

Now I tried to add the alchemy tasks to create the shared and symlinks:

gemfile:

group :development do

  gem 'capistrano-alchemy', github: 'AlchemyCMS/capistrano-alchemy', branch: 'master', require: false

  gem 'capistrano', '~> 3.1.0', require: false

  gem 'capistrano-rails', '~> 1.1.0', require: false

  gem 'capistrano-bundler', require: false

  gem 'capistrano-passenger', require: false

  gem 'capistrano-rvm', require: false

end

deploy.rb:

namespace :deploy do

  after "deploy:setup", "alchemy:shared_folders:create"

  after "deploy:finalize_update", "alchemy:shared_folders:symlink"

  after :restart, :clear_cache do

    on roles(:web), in: :groups, limit: 3, wait: 10 do

  end

  end

end

Added this line to capfile.rb:

require 'capistrano/alchemy'

And then do: 

• cap production deploy
  

cap aborted!

LoadError: cannot load such file -- capistrano/alchemy

Capfile:26:in `<top (required)>'

What am I missing? Why can't I add the alchemy tasks to capistrano?

Thank you

[Thomas von Deyen]

If you have capistrano-alchemy in your Gemfile only, then you need to run the command with:

$ bundle exec cap production deploy

Otherwise Ruby doesn't now about the Gem. 

Btw. You don't need to have the alchemy tasks in your deploy file. They are executed automatically. It's sufficient to require 'capistrano/alchemy' in your Capfile.

Hope this helps.

Thank you Thomas,

Yes, it works like you said.

However, I use Rubymine and in that way, I must use the command line to execute that...

My question is: I have many other recipes, from gems:

•  require 'capistrano/bundler'
  
•  require 'capistrano/rails/assets'
  
•  require 'capistrano/rails/migrations'
  
•  require 'capistrano/passenger'
  
•  require 'whenever/capistrano'
  

And all of them work with "cap production deploy"

But the alchemy doesn't. Is there any detail on the gem that prevents it to act like the other ones?

Or is there some other requirement that prevents it from working the same way?

Thank you for your help and magnificient work. If I can do something to help you, please tell me.

Best regards,

Nuno

The other gems probably work because you installed them via "gem install" not with "bundle install"?

I didn't install them by the command line.

I added them to gemfile and did: bundle install.

Is there any way to use this one as I was using the other? Must I remove the gem??

Thank you

[Thomas von Deyen]

As I said. Please try to remove the require: false argument from the "capistrano-alchemy" gem in your Gemfile and try again.

So now I have:

group :development do

  gem 'capistrano-alchemy', github: 'AlchemyCMS/capistrano-alchemy', branch: 'master'

  # Use Capistrano for deployment

  gem 'capistrano', '~> 3.2.0'

  # rails specific capistrano funcitons

  gem 'capistrano-rails', '~> 1.1.0'

  # integrate bundler with capistrano

  gem 'capistrano-bundler'

  # integrate bundler with passenger

  gem 'capistrano-passenger'

  gem 'capistrano-rvm'

  gem 'capistrano-faster-assets', '~> 1.0'

end

I ran bundle install, then bundle update.

Capfile:

 require 'capistrano/bundler'

 require 'capistrano/rails/assets'

 require 'capistrano/rails/migrations'

 require 'capistrano/passenger'

 require 'whenever/capistrano'

 require 'capistrano/faster_assets'

 require 'capistrano/alchemy'

Then using the rubymine I ran:

/home/nuno/.rvm/gems/ruby-2.1.6/bin/cap production deploy

(Backtrace restricted to imported tasks)

cap aborted!

LoadError: cannot load such file -- capistrano/alchemy

/home/nuno/Documents/RubymineWorkspace/FarmacoWebStore/Capfile:27:in `<top (required)>'

(See full trace by running task with --trace)

I can't figure out what I am doing wrong...

Sorry to bother.. I am still learning all this stuff...

Thank you Thomas 

[Thomas von Deyen]

Ok. 

The only thing that's different is that you are loading the capistrano-alchemy gem via GitHub. 

I guess that's why Ruby doesn't know where to load the lib from. Only Bundler knows where the gem is. 

That's nothing we can solve now. We need to publish the gem on Rubygems. Unfortunately I am on vacation right know and don't have a computer nearby. So you need to wait until next week. 

Sorry for that.

Thank you Thomas and good vacations ;)
