cfsystem

Description

Configure a bare minimal production system regardless of its purpose. It depends on more specific cfnetwork, cfauth and cffirehol modules.

What it does:

  • Whatever cfnetwork does
  • Whatever cfauth does
  • Whatever cffirehol does
  • Setups APT for Debian and Ubuntu
  • Setups timezone
  • Setups hostname based on certname
  • Adds firewall rules as required
  • Setups special location/pool facts for hiera lookup (see cfsystem::hierapool below)
  • Setups email system
  • Setups NTP daemon and command line client for large gap sync
  • Setup all locales and the default locale (configurable)
  • Manages /etc/profile.d/ & adds allowed bin paths to sudo search_paths
  • Installs many handy system tools which almost any admin would expect
  • Forces noop scheduler on SSDs and virtual devices (in guests)
  • Forces custom I/O scheduler for real spinning HDDs (deadline by default)
  • Adds custom rc.local commands, if needed
  • Adds cron job to check if running kernel version matches the latest installed (reboot reminder)
  • Auto-detect hardware nodes with IPMI
    • Install generic IPMI tools
    • Install Dell-specific tools
    • Other vendors - TODO
  • Ruby framework for other cf* modules

    • cf_clear_frozen_emails - clear only frozen emails in exim queue
    • cf_send_test_email - send test email to admin address
    • cf_kernel_version_check - check if kernel version mismatch the latest installed one
    • cf_auto_block_scheduler - setup auto-detected I/O scheduler per block device
    • cf_apt_key_updater <key_id> - run GPG key re-import, if expired
    • cf_ntpdate - run pre-configured ntpdate
  • Public API for Puppet parser:

    • cfsystem::add_group($user, $group) >> Resource - make sure user is part of the group
    • cfsystem::gen_key(name, params, forced_key) - generate or save persistent SSH key
    • cfsystem::gen_pass(name, length, forced_pass) - generate or save persistent password
    • cfsystem::gen_port(name, forced_port) - allocate or save persistent network port
    • cfsystem::pretty_json(data) - return pretty formatted JSON string
    • cf_notify - replacement of standard notify to avoid refresh side-effects

Technical Support

Setup

Up to date installation instructions are available in Puppet Forge: https://forge.puppet.com/codingfuture/cfsystem

Please use librarian-puppet or cfpuppetserver module to deal with dependencies.

There is a known r10k issue RK-3 which prevents automatic dependencies of dependencies installation.

Examples

Please check codingufuture/puppet-test for example of a complete infrastructure configuration and Vagrant provisioning.

    ---
    :backends:
    - yaml
    :hierarchy:
    - "%{::trusted.domain}/%{::trusted.hostname}"

    :datadir:
  • location = undef - if set, saved into /etc/cflocation
  • pool = undef - if set, aved into /etc/cflocationpool

  • copy_key = true - if true then private keys of local machine are copied as well
  • pki_dir = undef - override the default destination folder

cfsystem::haproxy class

cfsystem::sshdir type

Create a basic ~/.ssh/ directory for unattended user account.

  • $user = $title - system user with 'home' parameter

cfsystem::clusterssh type

This feature is trade-off between SSH setup in cluster and security. This functionality creates a single SSH client key and shares across all nodes in cluster. It helps to get rid of puppet facts processing for target-generated secrets.

Besides shared private key, another problem is clear-text private key getting into puppet catalog (which should be secured as well).

  • $namespace - cluster namespace, e.g. 'cfdb'

cfsystem::hwm::generic class

Just a placeholder for generic IPMI system.

cfsystem::hwm::dell class

Support for Dell PowerEdge family.

  • $community_repo = 'http://linux.dell.com/repo/community'

cfsystem::hwm::smc class

Placeholder for SuperMicro support. Not implemented yet.

cfsystem::pip class

Setup latest pip for Python 2&3 into /usr/local.

cfsystem::metric type

Mostly for internal purposes to declare items for cfmetrics monitoring.

cf_notify type

The standard notify type has a side effect - it generates refresh event what may harm automation which expects 0 exit code on no resource changes. Therefore, this drop-in replacement has been provided.

  • message = $title - message to show
  • loglevel = info - log level to use for the message

cfsystem_service type

Helper type to create cfsystem-integrated services.

cfsystem_timer type

Helper type to create cfsystem-integrated cron-like services.
