How to hide "failed dependencies" logs on puppet

  • 772

I would like to avoid (or hide at least) "failed dependencies" logs on puppet.

I want to deploy files only if exec requirement are true. It's working but puppet shows a lot of err/warning logs :

Error: /usr/bin/test -e /home/USER returned 1 instead of one of [0]
Error: /Stage[main]/Users::Config/Exec[/usr/bin/test -e /home/USER]/returns: change from notrun to 0 failed: /usr/bin/test -e /home/USER returned 1 instead of one of [0]

Warning: /Stage[main]/Users::Config/File[/home/USER/.ssh/authorized_keys]: Skipping because of failed dependencies

Here is my config.pp :

class users::config ($user) {

    exec {"/usr/bin/test -e /home/${user}":
    }

    exec {"check_ssh_dir":
        command => '/bin/true',
        onlyif => "/usr/bin/test -e /home/${user}/.ssh",
        require => Exec["/usr/bin/test -e /home/${user}"],
    }

    file {"/home/${user}/.ssh":
        ensure => directory,
        owner   => "${user}",
        group   => "domain users",
        mode    => "700",
        require => Exec['check_ssh_dir'],
    }

    file {"/home/${user}/.bashrc":
        source => [ "puppet:///modules/users/${user}/bashrc", "puppet:///modules/users/basics/bashrc"],
        owner   => "${user}",
        group   => "domain users",
        mode    => "640",
        require => Exec["/usr/bin/test -e /home/${user}"],
    }

    file {"/home/${user}/.bash_profile":
        source => [ "puppet:///modules/users/${user}/bash_profile", "puppet:///modules/users/basics/bash_profile"],
        owner   => "${user}",
        group   => "domain users",
        mode    => "640",
        require => Exec["/usr/bin/test -e /home/${user}"],
    }

    file {"/home/${user}/.ssh/authorized_keys":
        source => [ "puppet:///modules/users/${user}/ssh/authorized_keys", "puppet:///modules/users/basics/ssh/authorized_keys"],
        owner   => "${user}",
        group   => "domain users",
        mode    => "600",
        require => Exec["check_ssh_dir"],
    }
}

I'm using puppet 4.3.

Thanks for helping.

  1. This is not really possible without using facts or implementing a custom provider. To be sure, with exec resources you can do something like this:

    exec { 'test-user-exists:
    command => '/bin/true',
    onlyif  => "/usr/bin/test -e /home/${user}"
} ~>
exec { 'conditional-command':
    command     => '/usr/bin/my-command',
    refreshonly => true,
}

    But you won't be able to have conditional file resources on the result of the a command. The easiest option is to create a fact. Something like:

    Facter.add(:avail_users) do
  setcode do
    IO.
      readlines('/etc/passwd').
      map { |x| x.split(':')[0] }
  end
end

    Then you could check if $user was in the array $::avail_users in an if block. Make sure you don't have stringify_facts on.

    I have found how to solve my issue thanks to @Artefacto :

    I have created a new fact which just list homes :

    Facter.add(:list_home) do
    setcode do
        Facter::Core::Execution.exec('/bin/ls /home/').split("\n")
    end
end

    And I have modified my manifest to iterate on each home :

    class users::config {

    $::list_home.each |String $user| {
        exec {"check_ssh_dir_${user}":
            command => '/bin/true',
            onlyif => "/usr/bin/test -e /home/${user}/.ssh",
        }

        file {"/home/${user}/.ssh":
            ensure => directory,
            owner   => "${user}",
                    group   => "domain users",
                    mode    => "700",
            require => Exec["check_ssh_dir_${user}"],
        }

        file {"/home/${user}/.bashrc":
            source => [ "puppet:///modules/users/${user}/bashrc", "puppet:///modules/users/basics/bashrc"],
            owner   => "${user}",
            group   => "domain users",
            mode    => "640",
        }

        file {"/home/${user}/.bash_profile":
            source => [ "puppet:///modules/users/${user}/bash_profile", "puppet:///modules/users/basics/bash_profile"],
            owner   => "${user}",
            group   => "domain users",
            mode    => "640",
        }

        file {"/home/${user}/.ssh/authorized_keys":
            source => [ "puppet:///modules/users/${user}/ssh/authorized_keys", "puppet:///modules/users/basics/ssh/authorized_keys"],
            owner   => "${user}",
            group   => "domain users",
            mode    => "600",
        }
    }
}

    Now I have no failed due to dependencies.
