laravel - Getting started with chef, and running composer install on deploy -


we're looking deploy few laravel4 based php apps on amazon opsworks, requires few things:

  • grab code git
  • download composer.phar getcomposer.com
  • run php composer.phar install
  • change permissions on few specific folders

i'm fresh comes chef, looking place grips basics of chef, , how achieve tasks above, appreciate pointers.

i'm no chef guru (i use puppet) try following:

grab code git

you may want execute wget command (see examples below).

if want more sophisticated see http://docs.opscode.com/resource_deploy.html

deploy_revision "/path/to/application"   repo 'ssh://name-of-git-repo/repos/repo.git'   migrate false   purge_before_symlink %w{one 2 folder/three}   create_dirs_before_symlink []   symlinks(     "one"   => "one",     "two"   => "two",     "three" => "folder/three"   )   before_restart     # ruby code   end   notifies :restart, "service[foo]"   notifies :restart, "service[bar]" end

download composer.phar getcomposer.com

i execute wget.

i lifted code here: http://cookingclouds.com/2012/06/23/chef-simple-cookbook-example/

it's doing wget in specific folder, extracting contents of tar & updating permissions on new files. if folder doesn't exist.

# run bash shell -  download , extract composer bash "install_composer"      user "root"      cwd "/folder/to/extact/to"      code <<-eoh        wget http://getcomposer.com/composer.tar.gz        tar -xzf composer.tar.gz        chown -r user:group /folder/to/extact/to      eoh      not_if "test -d /folder/to/extact/to" end

run php composer.phar install

http://docs.opscode.com/resource_execute.html

execute "composer install"   command "php composer.phar install && touch /var/log/.php_composer_installed"   creates "/var/log/.php_composer_installed"   action :run end

this run once, otherwise can remove "creates" , run each time.

change permissions on few specific folders

http://docs.opscode.com/resource.html

directory "/tmp/folder"   owner "root"   group "root"   mode 0755   action :create end

if directory exists, nothing happen. if directory changed in way, resource marked updated.

finally

i find search handy, browsing stuff on chef site seems hopeless (too stuff dig through). http://docs.opscode.com/search.html

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
