Upgrading

All definitions have been removed and replaced with custom resources. As a result we are now providing the default assigned names:

  • apache_mod --> apache2_mod
  • apache_conf --> apache2_conf
  • apache_site --> apache2_site

This helps as resource behaviours have been significantly changed to remove magic where possible.

apache_module

Having a module disabled is now an action on the resource:

# Old Style
apache_module "disabled_module" do
  enable false
end
# New Style
apache2_module "disabled_module" do
  action :disable
end

Where did the apache2 recipes go

Recipes are now modules, so your cookbook pattern will go from

include_recipe 'apache2'
include_recipe 'apache2::mod_proxy'
include_recipe 'apache2::mod_proxy_http'
include_recipe 'apache2::mod_ssl'

to

apache2_install 'default_install'
apache2_module 'headers'
apache2_module 'proxy'
apache2_module 'proxy_http'
apache2_module 'rewrite'
apache2_module 'ssl'

What happened to all my attributes

In custom resources having & using a global variable like attributes makes the cookbook brittle and hard to test.

These have been removed in favour of tunable properties on each resource. Please see the documentation directory for all tunables.

What happened to apache2_web_app

The apache2_web_app resource was a wrapper around the template resource and apache2_site that provided little value, and restricted the the users ability to provide all the variables possible.

It is recommended that you manage your template and call the apache2_site resource directly.

This leads to a simpler system, and you get more control over the variables and values you pass to the template.

Here are the modifications you will need to make:

web_app 'ssl_redirect' do
  server_name node['hostname']
  server_port '80'
  docroot '/var/www/'
  template 'ssl_redirect.conf.erb'
  notifies :restart, 'service[apache2]', :delayed
end

to

apache2_default_site 'ssl_redirect' do
  default_site_name 'ssl_redirect'
  cookbook 'my_cookbook'
  port '80'
  template_source 'ssl_redirect.conf.erb'
  action :enable
end

A further example of this behaviour can be seen in the apache2_default_site resource.

The service resource

whilst service['apache2'] is defined in the apache2_install resource, due to the notification system of nested resources, we are unable to notify or subscribe directly to it.

To work around this issue, define the following helper in your cookbook:

service 'apache2' do
  service_name lazy { apache_platform_service_name }
  supports restart: true, status: true, reload: true
  action :nothing
end
