yum Cookbook

The Yum cookbook exposes the yum_globalconfig and yum_repository resources that allows a user to both control global behavior and make individual Yum repositories available for use. These resources aim to allow the user to configure all options listed in the yum.conf man page, found at http://linux.die.net/man/5/yum.conf

NOTES

WARNING: Yum cookbook version 3.0.0 and above contain non-backwards compatible breaking changes and will not work with cookbooks written against the 2.x and 1.x series. Changes have been made to the yum_repository resource, and the yum_key resource has been eliminated entirely. Recipes have been eliminated and moved into their own cookbooks. Please lock yum to the 2.x series in your Chef environments until all dependent cookbooks have been ported.

Requirements

  • Chef 11 or higher
  • Ruby 1.9 (preferably from the Chef full-stack installer)
  • RHEL5, RHEL6, or other platforms within the family

Resources/Providers

yum_repository

This resource manages a yum repository configuration file at /etc/yum.repos.d/repositoryid.repo. When the file needs to be repaired, it calls yum-makecache so packages in the repo become available to the next resource.

Example

# add the Zenoss repository
yum_repository 'zenoss' do
  description "Zenoss Stable repo"
  baseurl "http://dev.zenoss.com/yum/stable/"
  gpgkey 'http://dev.zenoss.com/yum/RPM-GPG-KEY-zenoss'
  action :create
end

# add the EPEL repo
yum_repository 'epel' do
  description 'Extra Packages for Enterprise Linux'
  mirrorlist 'http://mirrors.fedoraproject.org/mirrorlist?repo=epel-6&arch=$basearch'
  gpgkey 'http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6'
  action :create
end
# delete CentOS-Media repo
yum_repository 'CentOS-Media' do
  action :delete
end

Actions

  • :create - creates a repository file and builds the repository listing
  • :delete - deletes the repository file

Parameters

  • baseurl - Must be a URL to the directory where the yum repository's 'repodata' directory lives. Can be an http://, ftp:// or file:// URL. You can specify multiple URLs in one baseurl statement.
  • cost - relative cost of accessing this repository. Useful for weighing one repo's packages as greater/less than any other. defaults to 1000
  • description - Maps to the 'name' parameter in a repository .conf. Descriptive name for the repository channel. This directive must be specified.
  • enabled - Either true or false. This tells yum whether or not use this repository.
  • enablegroups - Either true or false. Determines whether yum will allow the use of package groups for this repository. Default is true (package groups are allowed).
  • exclude - List of packages to exclude from updates or installs. This should be a space separated list in a single string. Shell globs using wildcards (eg. * and ?) are allowed.
  • failovermethod - Either 'roundrobin' or 'priority'.
  • fastestmirror_enabled - Either true or false
  • gpgcheck - Either true or false. This tells yum whether or not it should perform a GPG signature check on packages. When this is set in the [main] section it sets the default for all repositories. The default is true.
  • gpgkey - A URL pointing to the ASCII-armored GPG key file for the repository. This option is used if yum needs a public key to verify a package and the required key hasn't been imported into the RPM database. If this option is set, yum will automatically import the key from the specified URL.
  • http_caching - Either 'all', 'packages', or 'none'. Determines how upstream HTTP caches are instructed to handle any HTTP downloads that Yum does. Defaults to 'all'
  • includepkgs - Inverse of exclude. This is a list of packages you want to use from a repository. If this option lists only one package then that is all yum will ever see from the repository. Defaults to an empty list.
  • keepalive - Either true or false. This tells yum whether or not HTTP/1.1 keepalive should be used with this repository.
  • max_retries - Set the number of times any attempt to retrieve a file should retry before returning an error. Setting this to '0' makes yum try forever. Default is '10'.
  • metadata_expire - Time (in seconds) after which the metadata will expire. So that if the current metadata downloaded is less than this many seconds old then yum will not update the metadata against the repository. If you find that yum is not downloading information on updates as often as you would like lower the value of this option. You can also change from the default of using seconds to using days, hours or minutes by appending a d, h or m respectively. The default is 6 hours, to compliment yum-updatesd running once an hour. It's also possible to use the word "never", meaning that the metadata will never expire. Note that when using a metalink file the metalink must always be newer than the metadata for the repository, due to the validation, so this timeout also applies to the metalink file.
  • mirrorlist - Specifies a URL to a file containing a list of baseurls. This can be used instead of or with the baseurl option. Substitution variables, described below, can be used with this option. As a special hack is the mirrorlist URL contains the word "metalink" then the value of mirrorlist is copied to metalink (if metalink is not set)
  • mirror_expire - Time (in seconds) after which the mirrorlist locally cached will expire. If the current mirrorlist is less than this many seconds old then yum will not download another copy of the mirrorlist, it has the same extra format as metadata_expire. If you find that yum is not downloading the mirrorlists as often as you would like lower the value of this option.
  • mirrorlist_expire - alias for mirror_expire
  • priority - When the yum-priorities plug-in is enabled, you set priorities on repository entries, where N is an integer from 1 to 99. The default priority for repositories is 99.
  • proxy - URL to the proxy server that yum should use.
  • proxy_username - username to use for proxy
  • proxy_password - password for this proxy
  • report_instanceid - Report instance ID when using Amazon Linux AMIs and repositories
  • repositoryid - Must be a unique name for each repository, one word. Defaults to name attribute.
  • source - Use a custom template source instead of the default one in the yum cookbook
  • sslcacert - Path to the directory containing the databases of the certificate authorities yum should use to verify SSL certificates. Defaults to none - uses system default
  • sslclientcert - Path to the SSL client certificate yum should use to connect to repos/remote sites Defaults to none.
  • sslclientkey - Path to the SSL client key yum should use to connect to repos/remote sites Defaults to none.
  • sslverify - Either true or false. Determines if yum will verify SSL certificates/hosts. Defaults to true
  • timeout - Number of seconds to wait for a connection before timing out. Defaults to 30 seconds. This may be too short of a time for extremely overloaded sites.

yum_globalconfig

This renders a template with global yum configuration parameters. The default recipe uses it to render /etc/yum.conf. It is flexible enough to be used in other scenarios, such as building RPMs in isolation by modifying installroot.

Example

yum_globalconfig '/my/chroot/etc/yum.conf' do
  cachedir '/my/chroot/etc/yum.conf'
  keepcache 'yes'
  debuglevel '2'
  installroot '/my/chroot'
  action :create
end

Parameters

yum_globalconfig can take most of the same parameters as a yum_repository, plus more, too numerous to describe here. Below are a few of the more commonly used ones. For a complete list, please consult the yum.conf man page, found here: http://linux.die.net/man/5/yum.conf

  • cachedir - Directory where yum should store its cache and db files. The default is '/var/cache/yum'.
  • keepcache - Either true or false. Determines whether or not yum keeps the cache of headers and packages after successful installation. Default is true (keep files)
  • debuglevel - Debug message output level. Practical range is 0-10. Default is '2'.
  • exclude - List of packages to exclude from updates or installs. This should be a space separated list. Shell globs using wildcards (eg. * and ?) are allowed.
  • installonlypkgs = List of package provides that should only ever be installed, never updated. Kernels in particular fall into this category. Defaults to kernel, kernel-bigmem, kernel-enterprise, kernel-smp, kernel-debug, kernel-unsupported, kernel-source, kernel-devel, kernel-PAE, kernel-PAE-debug.
  • logfile - Full directory and file name for where yum should write its log file.
  • exactarch - Either true or false. Set to true to make 'yum update' only update the architectures of packages that you have installed. ie: with this enabled yum will not install an i686 package to update an x86_64 package. Default is true
  • gpgcheck - Either true or false. This tells yum whether or not it should perform a GPG signature check on the packages gotten from this repository.

Recipes

  • default - Configures yum_globalconfig[/etc/yum.conf] with values found in node attributes at node['yum']['main']

Attributes

The following attributes are set by default

default['yum']['main']['cachedir'] = '/var/cache/yum/$basearch/$releasever'
default['yum']['main']['keepcache'] = false
default['yum']['main']['debuglevel'] = nil
default['yum']['main']['exclude'] = nil
default['yum']['main']['logfile'] = '/var/log/yum.log'
default['yum']['main']['exactarch'] = nil
default['yum']['main']['obsoletes'] = nil
default['yum']['main']['installonly_limit'] = nil
default['yum']['main']['installonlypkgs'] = nil
default['yum']['main']['installroot'] = nil
