chef-ark

Overview

An ''ark'' is like an archive but ''Kewler''

Does the fetch-unpack-configure-build-install dance. This is a modified verion of Infochimps awesome install_from cookbook [http://github.com/infochimps-cookbooks/install_from]. It has been heavily refactored and extended to meet different use cases.

Given a simple project archive available at a url:

ark 'pig' do
  url 'http://apache.org/pig/pig-0.8.0.tar.gz'
end

this provider will

• fetch it to to /var/cache/chef/
• unpack it to the default path (/usr/local/pig-0.8.0)
• create a symlink for :home_dir (/usr/local/pig) pointing to path
• add specified binary commands to the enviroment PATH variable

By default, the ark will not run again if the :path is not empty. Ark provides many actions to accommodate different use cases, such as :dump, :cherry_pick, :put, and :install_with_make.

At this time ark only handles files available from URLs. It does not handle local files.

Attributes

Customize the attributes to suit site specific conventions and defaults.

• node['ark']['apache_mirror'] - if the URL is an apache mirror, use the attribute as the default.
• node['ark']['prefix_root'] - default base location if the prefix_root is not passed into the resource.
• node['ark']['prefix_bin'] - default binary location if the prefix_bin is not passed into the resource.
• node['ark']['prefix_home'] - default home location if the prefix_home is not passed into the resource.

Resources/Providers

• ark - does the extract/build/configure dance

Actions

• :install: extracts the file and creates a 'friendly' symbolic link to the extracted directory path
• :configure: configure ahead of the install action
• :install_with_make: extracts the archive to a path, runs make, and make install. It does not run the configure step at this time
• :dump: strips all directories from the archive and dumps the contained files into a specified path
• :cherry_pick: extract a specified file from an archive and places in specified path
• :put: extract the archive to a specified path, does not create any symbolic links
• :remove: removes the extracted directory and related symlink #TODO
• :setup_py_build: runs the command "python setup.py build" in the extracted directory
• :setup_py_install: runs the comand "python setup.py install" in the extracted directory

:put

Extract the archive to a specified path, does not create any symbolic links.

Attribute Parameters for :put

• path: path to extract to.
  • Default: /usr/local
• has_binaries: array of binary commands to symlink into /usr/local/bin/, you must specify the relative path.
  • Example: [ 'bin/java', 'bin/javaws' ]
• append_env_path: boolean, if true, append the ./bin directory of the extracted directory to the global PATH variable for all users.

:dump

Strips all directories from the archive and dumps the contained files into a specified path.

NOTE: This currently only works for zip archives

Attribute Parameters for :dump

• path: path to dump files to.
• mode: file mode for app_home, as an integer.
  • Example: 0775
• creates: if you are appending files to a given directory, ark needs a condition to test whether the file has already been extracted. You can specify with creates, a file whose existence indicates the ark has previously been extracted and does not need to be extracted again.

:cherry_pick

Extract a specified file from an archive and places in specified path.

Relevant Attribute Parameters for :cherry_pick

• path: directory to place file in.
• creates: specific file to cherry-pick.

Attribute Parameters

• name: name of the package, defaults to the resource name.
• url: url for tarball, .tar.gz, .bin (oracle-specific), .war, and .zip currently supported. Also supports special syntax :name:version:apache_mirror: that will auto-magically construct download url from the apache mirrors site.
• version: software version, defaults to 1.
• checksum: sha256 checksum, used for security .
• mode: file mode for app_home, is an integer.
• prefix_root: default prefix_root, for use with :install* actions.
• prefix_home: default directory prefix for a friendly symlink to the path.
  • Example: /usr/local/maven -> /usr/local/maven-2.2.1
• prefix_bin: default directory to place a symlink to a binary command.
  • Example: /opt/bin/mvn -> /opt/maven-2.2.1/bin/mvn, where the prefix_bin is /opt/bin
• path: path to extract the ark to. The :install* actions overwrite any user-provided values for :path.
  • Default: /usr/local/<name>-<version> for the :install, :install_with_make actions
• home_dir: symbolic link to the path :prefix_root/:name-:version, does not apply to :dump, :put, or :cherry_pick actions.
  • Default: :prefix_root/:name
• has_binaries: array of binary commands to symlink into /usr/local/bin/, you must specify the relative path.
  • Example: [ 'bin/java', 'bin/javaws' ]
• append_env_path: boolean, similar to has_binaries but less granular. If true, append the ./bin directory of the extracted directory to. the PATH environment variable for all users, by placing a file in /etc/profile.d/. The commands are symbolically linked into /usr/bin/*. This option provides more granularity than the boolean option.
  • Example: mvn, java, javac, etc.
• environment: hash of environment variables to pass to invoked shell commands like tar, unzip, configure, and make.
• strip_leading_dir: by default, ark strips the leading directory from an archive, which is the default for both unzip and tar commands
• autoconf_opts: an array of command line options for use with the GNU autoconf script.
  • Example: [ '--include=/opt/local/include', '--force' ]
• make_opts: an array of command line options for use with make.
  • Example: [ '--warn-undefined-variables', '--load-average=2' ]
• owner: owner of extracted directory.
  • Default: root

Examples

 # install Apache Ivy dependency resolution tool
 ark "ivy" do
   url 'http://someurl.example.com/ivy.tar.gz'
   version '2.2.0'
   checksum '89ba5fde0c596db388c3bbd265b63007a9cc3df3a8e6d79a46780c1a39408cb5'
   action :install
 end

This example copies ivy.tar.gz to /var/cache/chef/ivy-2.2.0.tar.gz, unpacks its contents to /usr/local/ivy-2.2.0/ -- stripping the leading directory, and symlinks /usr/local/ivy to /usr/local/ivy-2.2.0

 ark 'jdk' do
   url 'http://download.example.com/jdk-7u2-linux-x64.tar.gz'
   version '7.2'
   path "/usr/local/jvm/"
   home_dir "/usr/local/jvm/default"
   checksum  '89ba5fde0c596db388c3bbd265b63007a9cc3df3a8e6d79a46780c1a39408cb5'
   append_env_path true
   owner 'foobar'
 end

This example copies jdk-7u2-linux-x64.tar.gz to /var/cache/chef/jdk-7.2.tar.gz, unpacks its contents to /usr/local/jvm/jdk-7.2/ -- stripping the leading directory, symlinks /usr/local/jvm/default to /usr/local/jvm/jdk-7.2, and adds /usr/local/jvm/jdk-7.2/bin/ to the global PATH for all users. The user 'foobar' is the owner of the /usr/local/jvm/jdk-7.2 directory

 # install Apache Ivy dependency resolution tool
 # in <path>/resource_name in this case
 # /usr/local/ivy, no symlink created
 # it strips any leading directory if one exists in the tarball

 ark "ivy" do
    url 'http://someurl.example.com/ivy.tar.gz'
    checksum '89ba5fde0c596db388c3bbd265b63007a9cc3df3a8e6d79a46780c1a39408cb5'
    action :put
 end

 # install Apache Ivy dependency resolution tool
 # in /home/foobar/ivy
 # it does strip any leading directory if one exists

 ark "ivy" do
   path "/home/foobar
   url 'http://someurl.example.com/ivy.tar.gz'
   checksum '89ba5fde0c596db388c3bbd265b63007a9cc3df3a8e6d79a46780c1a39408cb5'
   action :put
 end

# strip all directories and dump files into path specified by
 # the path attribute, you must specify the `creates` attribute
 # in order to keep the extraction from running every time
 # the directory path will be created if it doesn't already exist

 ark "my_jars" do
   url  "http://example.com/bunch_of_jars.zip"
   path "/usr/local/tomcat/lib"
   creates "mysql.jar"
   owner "tomcat"
   action :dump
 end

 # extract specific files from a tarball, currently only handles
 # one named file

 ark 'mysql-connector-java' do
   url 'http://oracle.com/mysql-connector.zip'
   creates 'mysql-connector-java-5.0.8-bin.jar'
   path '/usr/local/tomcat/lib'
   action :cherry_pick
 end

 # build and install haproxy and use alternave values for
 # prefix_root, prefix_home, and prefix_bin

 ark "haproxy" do
   url  "http://haproxy.1wt.eu/download/1.5/src/snapshot/haproxy-ss-20120403.tar.gz"
   version "1.5"
   checksum 'ba0424bf7d23b3a607ee24bbb855bb0ea347d7ffde0bec0cb12a89623cbaf911'
   make_opts [ 'TARGET=linux26' ]
   prefix_root '/opt'
   prefix_home '/opt'
   prefix_bin  '/opt/bin'
   action :install_with_make
 end

 # you can also pass multiple actions to ark and supply the file extension
 # in case the file extension can not be determined by the URL

 ark "test_autogen" do
   url 'https://github.com/zeromq/libzmq/tarball/master'
   extension "tar.gz"
   action [ :configure, :build_with_make ]
 end

 # you can also pass multiple actions to ark and supply the file extension
