5.2.6. HOWTO Generate a Puppetfile

This section describes how to create a Puppetfile to be used by r10k or code manager to deploy SIMP and site modules. It assumes the user is on the puppetserver. It covers building from Local Repositories or using the Internet repositories


Any module not listed in the Puppetfile will be deleted from the target environment’s modules directory, when you use r10k to deploy the modules. Generate the Puppetfile skeleton

simp puppetfile generate -s > Puppetfile Edit the Puppetfile to include non-simp site modules

Make sure the Puppetfile used to deploy from includes the following:

  • A line that includes the Puppetfile.simp which should look like:

  • A line for each of your own modules.

    The SIMP CLI can help identify local modules in an environment that need to be listed in the Puppetfile, because they may not be under Git source control and, when removed by r10k, may not be able to be readily restored.

    To generate a list of local modules in an environment (production in this example) do the following:

    simp puppetfile generate --skeleton --local-modules production  > /tmp/Puppetfile

    This will generate /tmp/Puppetfile which has

    • a directive to include the file Puppetfile.simp

    • a local entry for each module presently in the production environment, that does not have a local, SIMP-managed Git repository and does not appear to be managed by Git.

    The local entries will look like the following:

    mod 'module name', :local => true

    Verify that all modules with a local entry in /tmp/Puppetfile are in your environment’s Puppetfile in one of the following forms:

    # a module that is not a Git repository and resides in the ``modules`` directory
    mod 'site',
      :local => true
    # a Git repository that resides in a directory on the Puppet server
    mod 'mymodule',
     :git => 'file:///usr/share/mymodules/mymodule',
     :tag => '1.1.1'
    #  a Git repository on a remote server
    mod 'mysrvmod',
      :git => 'https://gitserver.my.domain/mygitproject/mysrvmod.git',
      :tag => '1.0.1'


    Any modules on the local system (ones that use the :local => true directive), should be converted to a Git repository. This will ensure that if r10k removes them because of an error in the Puppetfile they can easily be restored from the Git repository. Generate the Puppetfile.simp file Using local SIMP git repositories

Make sure all the SIMP module RPMs are installed using yum that you want to use and then run:

simp puppetfile generate > Puppetfile.simp Using SIMP internet repositories

  • Download the Puppetfile used to create a SIMP ISO for a specific release from the SIMP simp-core repository. This example uses the SIMP 6.4.0-0 release.

    curl -o Puppetfile.simp https://github.com/simp/simp-core/blob/6.4.0-0/Puppetfile.pinned
  • Manually edit the Puppetfile.simp to remove components that are not Puppet modules, by deleting all lines up to and including moduledir 'src/puppet/modules'.

  • Optionally, edit the Puppetfile.simp to remove any non-core SIMP modules that are packaged with the simp-extras RPM, that are not needed. The list of the SIMP extra modules can be obtained by examining the RPM requirements of the simp-extras RPM as follows:

    yum deplist simp-extras

Copy the Puppetfile and Puppetfile.simp to top level of the environment directory or the top level of the control repo.
