ansible-role-red_hat_utility_modules

An Ansible role that contains re-useable miscellaneous utility modules for various Red Hat tools and products.

These are modules that are not currently shipped with Ansible but others may find useful. They are distributed in a role for easier consumption so the user does not need to copy paste the module files into their own repositories and rather can do a dynamic role requirement to pull in these modules.

Modules

redhat_check_rpms.py

This module checks a list of RPMs against a target systems RPMs. The idea is that using this module you can verify if a set of RPMs either exists or are absent from a target system. Some of our customers use this to ensure that a system, after it has been provisioned, contains the exact RPM set that was expected.

EXAMPLES:

  - name: Check RPMs are present
    redhat_check_rpms:
      rpms: ['iwl1000-firmware-39.31.5.1-69.el7.noarch','pygpgme-0.3-9.el7.x86_64','iwl3160-firmware-22.0.7.0-69.el7.noarch','yum-rhn-plugin-2.0.1-10.el7.noarch','python-chardet-2.2.1-1.el7_1.noarch','setools-libs-3.3.8-4.el7.x86_64','ncurses-libs-5.9-14.20130511.el7_4.x86_64','libcgroup-0.41-20.el7.x86_64']
       state: present
    register: response
 
  - debug: var=response
 
  - name: Check that RPMs are absent
    redhat_check_rpms:
      rpms: ['iwl1000-firmware-39.31.5.1-69.el7.noarch','pygpgme-0.3-9.el7.x86_64','iwl3160-firmware-22.0.7.0-69.el7.noarch','yum-rhn-plugin-2.0.1-10.el7.noarch','python-chardet-2.2.1-1.el7_1.noarch','setools-libs-3.3.8-4.el7.x86_64','ncurses-libs-5.9-14.20130511.el7_4.x86_64','libcgroup-0.41-20.el7.x86_64']
      state: absent
    register: response
 
  - debug: var=response

redhat_check_yum_pkgs.py

This module s not much different than the redhat_check_rpms module. The difference is that it uses the Yum DB to check a list of RPM packagess against a target systems installed RPMs. This is supposed to be faster than using the standard yum command to check for installed packages. You can use this module in the case you want to check if packges are already installed ('present') on a system before installing them using the Ansible 'package' mpdule. Some of our customers use this to ensure that a system, after it has been provisioned, contains the exact RPM set that were expected.

Also notice that we don't pass use the full rpm package name that normally includes the version.

EXAMPLES:

  - name: Check that RPM packages are present
    redhat_check_yum_pkgs:
      pkgs: ['pygpgme','yum-rhn-plugin','setools-libs','ncurses-libs','libcgroup']
      state: present
    register: response
 
  - debug: var=response

redhat_check_repo_status.py

This module checks that the repositories on a target system are either enabled or disabled. The idea is that using this module you can verify the repositories that are enabled without having to run subscription-manager on each target system. This module checks the "redhat.repo" file in the /etc/yum.repos.d directory by default but a different repo file can be speficied using the repofile: argument.

EXAMPLES:

  - name: Checking Repositories are enabled
    redhat_check_repo_status:
      repos: ['rhel-7-server-extras-rpms']
      status: 1
    register: response

  - name: Debug
    debug:
      var: response.repostat

  - name: Checking Repositories are enabled
    redhat_check_repo_status:
      repos: ['rhel-7-server-extras-rpms']
      repofile: /etc/yum.repos.d/myrepofile.repo
      status: 1
    register: response

  - name: Debug
    debug:
      var: response.repostat
