Description

Requirements

Chef

Platform

Cookbooks

Installation

Depending on the situation and use case there are several ways to install this cookbook. All the methods listed below assume a tagged version release is the target, but omit the tags to get the head of development. A valid Chef repository structure like the [Opscode repo][chef_repo] is also assumed.

Using Librarian

The [Librarian][librarian] gem aims to be Bundler for your Chef cookbooks. Include a reference to the cookbook in a Cheffile and run librarian-chef install. To install with Librarian:

gem install librarian
cd chef-repo
librarian-chef init
cat >> Cheffile <<END_OF_CHEFFILE
cookbook 'webapp',
  :git => 'git://github.com/fnichol/chef-webapp.git', :ref => 'v0.2.0'
END_OF_CHEFFILE
librarian-chef install

Using knife-github-cookbooks

The [knife-github-cookbooks][kgc] gem is a plugin for knife that supports installing cookbooks directly from a GitHub repository. To install with the plugin:

gem install knife-github-cookbooks
cd chef-repo
knife cookbook github install fnichol/chef-webapp/v0.2.0

As a Git Submodule

A common practice (which is getting dated) is to add cookbooks as Git submodules. This is accomplishes like so:

cd chef-repo
git submodule add git://github.com/fnichol/chef-webapp.git cookbooks/webapp
git submodule init && git submodule update

Note: the head of development will be linked here, not a tagged release.

As a Tarball

If the cookbook needs to downloaded temporarily just to be uploaded to a Chef Server or Opscode Hosted Chef, then a tarball installation might fit the bill:

cd chef-repo/cookbooks
curl -Ls https://github.com/fnichol/chef-webapp/tarball/v0.2.4 | tar xfz - && \
  mv fnichol-chef-webapp-* webapp

Actions

Action Description Default
create Create the resources needed to host a web application with a name and deployment profile. Yes
delete Remove the web application and its stubs.
disable Disable the web application from being able to serve itself.

Attributes

Attribute Description Default value
name Name attribute: A unique identifier for the web application. This will be used for directory naming among other things. nil
profile Declare the kind of web application that will be hosted. Current supported profiles are static, rack, rails, and php. static
user User that will own the web application and possibly control its deployment. deploy
group Group that will be used when set ownership on files and directories relating to the web application. The value of the user attribute.
host_name The primary host name that will be set in the virtual host configuration. node[:fqdn]
host_aliases An array of additonal host name aliases that the web server will respond to. []
non_ssl_server Create a non-SSL virtual host for this web application? true
listen_ports An array of non-SSL ports that the web server will listen on for this web application. [ 80 ]
www_redirect Create a virtual host that redirects http://www.<host> traffic to http://<host>? true
ssl_server Create an SSL virtual host for this web application? false
ssl_listen_ports An array of SSL ports that the web server will listen on for this web application. [ 443 ]
ssl_www_redirect Create a virtual host that redirects https://www.<host> traffic to https://<host>? true
ssl_cert The public key for the SSL certificate. ssl-cert-snakeoil.pem
ssl_key The private key for the SSL certificate. ssl-cert-snakeoil.key

Examples

A Rack Web Application Skel

webapp_site_skel "wiki" do
  profile         "rack"
  host_name       "wiki.example.com"
  www_redirect    false
end

Note: Setting www_redirect here will prevent the server from responding to traffic on http://www.wiki.example.com.

An SSL Rails Application

Here a custom SSL certificate was declared which needs to be supplied to server by other means. An additional non-SSL listen port of 3000 was also declared.

webapp_site_skel "redmine" do
  profile         "rails"
  host_name       "pm.example.com"
  listen_ports    [ 80, 3000 ]
  ssl_server      true
  ssl_cert        "ssl-cert-example.com.crt"
  ssl_key         "ssl-cert-example.com.key"
end

A PHP Application

Here is a questionable PHP site that needs to be taken diabled and taken offline. It also answers to multiple host names and www.* prefixes.

webapp_site_skel "wp" do
  profile         "php"
  host_name       "blog.example.com"
  host_aliases    [ "therealdeal.example.com", "example.com" ]
  user            "php_hack"
  action          :disable
end

Note: Disabling the web application will not delete it but de-register it from the web server's enabled virtual hosts.
