Capistrano 3: "find ... -exec ..." command syntax in task

Question

I am trying to integrate this shell command into a Capistrano 3 after deploy task:

find /var/www/mysite/somepath/ -type d -exec chmod 775 {} \;

However, I am failing at the proper Ruby syntax. I have tried most conceivable combinations between:

execute :find, "#{deploy_to}/somepath/ -type d -exec chmod 775 {} \;"

and

execute :find, "#{deploy_to}/somepath/", "-type d", "-exec", "chmod", "755", "{}", ";"

but invariably end up with the error: find: missing argument to -exec

Could anyone please help me with the proper way to separate the arguments of this command?

Answer 1

You are using wrong commands, :find is for using ruby functions, but you want to use find of linux utilities. Please try following

execute "find /var/www/mysite/somepath/ -type d -exec chmod 775 {} \\;"

Don't forget in the last I have double slashes to terminate command. But there is more good way to do it using following commands

set :file_permissions_paths, ["app/logs", "app/cache"]

I was using it in my very old project like following

set :permission_method, :chmod
set :use_set_permissions, true
set :writable_dirs, ["app/cache", "app/logs"]
set :file_permissions_paths, ["app/log", "app/cache", "storage"]

I think don't set permission of everything is really good idea, but when I did first time I was also getting confused so long time ago I have used following task which will go throughly and change all permission as you wanted

namespace :deploy do
  task :check_permissions do
    on roles(:web) do
      execute "chmod -R 0777 #{release_path}"
      execute "echo 'finished'"
      execute " /bin/systemctl restart nginx"
      #execute "cd #{deploy_to}/current && /usr/bin/env rake countries:update RAILS_ENV=production"
    end
  end
end

It has many things you remove and try what you want to do. Please note these are very old code, even I don't remember what are they doing, as I am not using capistrano any more to deploy but mostly dockers.
