A Gem that contains a lot of facts for a lot of Operating Systems.

facterdb 'facterversion=/^2.4\./ and (operatingsystem=Debian and operatingsystemrelease>=7 or operatingsystem=RedHat and operatingsystemrelease=/^7/)'

Will return a JSON containing the facts for Debian 7, Debian 8 and RedHat 7 generated by Facter 2.4.

require 'facterdb'
FacterDB::get_facts()

Returns an Array of Hash containing the whole facts database.

require 'facterdb'

FacterDB.get_facts([{:osfamily => 'Debian'}])

require 'facterdb'

FacterDB.get_facts({:osfamily => 'Debian'})

require 'facterdb'

FacterDB::get_facts('osfamily=Debian')

Where the number (1, 2 etc.) are the number of factsets for that OS and facter combination (e.g., x86_64 and i386 architectures)

There is Vagrantfile to automagically populate facts directory by spawning a new VM and launches a provisioning scripts.

$ cd facts
$ vagrant up --provision

Create i386 facts from x86_64's ones

for file in facts/*/*-x86_64.facts; do cat $file | sed -e 's/x86_64/i386/' -e 's/amd64/i386/' > $(echo $file | sed 's/x86_64/i386/'); done

Create RedHat, Scientific, OracleLinux facts from CentOS's ones

for file in facts/*/centos-*.facts; do cat $file | sed -e 's/CentOS/RedHat/' > $(echo $file | sed 's/centos/redhat/'); done
for file in facts/*/centos-*.facts; do cat $file | sed -e 's/CentOS/Scientific/' > $(echo $file | sed 's/centos/scientific/'); done
for file in facts/*/centos-*.facts; do cat $file | sed -e 's/CentOS/OracleLinux/' > $(echo $file | sed 's/centos/oraclelinux/'); done

The default facts are great for many things but there will be times when you need to have facterdb search custom fact sets that only make sense in your environment or might contain sensitive information.

This can be useful when combined with rspec_puppet_facts or the puppet-debugger which both use this gem.

To supply external facts to facterdb just set the FACTERDB_SEARCH_PATHS environment variable with one or more paths to your facts. Do this any time facterdb is used directly or indirectly.

When separating paths please use the default path separator character supported by your OS.

• Unix/Linux/OSX = :
• Windows = ;

Each fact set you create must meet the following requirements:

1. A JSON serialized file containing a single Hash of all the facts.
2. The facts file must end in .facts
3. Must be placed inside some directory. You can organize this directory however you like.

Facterdb is smart enough the search your supplied directories for files ending with '.facts'. You can even supply multiple directories.

Example:

FACTERDB_SEARCH_PATHS="/var/opt/lib/custom_facts"

or

FACTERDB_SEARCH_PATHS="/var/opt/lib/custom_facts:/tmp/custom_facts:/home/user1/custom_facts"

We still highly encourage you to create pull requests with new fact sets over of using external facts.

You can create these files via many methods.

• puppet facts | jq '.values' > /tmp/custom_facts/datacenter_a/2.4/os_x.facts # must have jq command
• Via puppetdb queries
• hand crafted

Additionally you can skip the default FacterDB facts completely by setting the environment variable FACTERDB_SKIP_DEFAULTDB. This will instruct facterdb to not look at its built-in facts which can be useful should you need to completely replace which facts are used.

Setting the variable FACTERDB_SKIP_DEFAULTDB to anything will disable the internal facts used by facterdb. You would most likely use this in combination with the FACTERDB_SEARCH_PATHS environment variable.

Example:

FACTERDB_SEARCH_PATHS="/var/opt/lib/custom_facts:/tmp/custom_facts:/home/user1/custom_facts"
FACTERDB_SKIP_DEFAULTDB='yes'

By setting the environment variable FACTERDB_INJECT_SOURCE the following facts are injected into all fact sets:

_facterdb_path : The base name of the file used to load this fact set e.g. centos-5-i386.facts

_facterdb_filename : The full path of the file used to load this fact set e.g. /project/facter-db/centos-5-i386.facts

{
  "_facterdb_path": "centos-5-i386.facts",
  "_facterdb_filename": "/project/facter-db/centos-5-i386.facts",
  "aio_agent_version": "1.8.3",
  "architecture": "i386",
  "augeas": {
    "version": "1.4.0"
  },
  "augeasversion": "1.4.0",
  "bios_release_date": "07/30/2013",
  "bios_vendor": "Phoenix Technologies LTD",
  "bios_version": "6.00",
  "blockdevice_fd0_size": 4096,
  "blockdevice_hdc_size": 4294965248,
  "blockdevice_sda_model": "Virtual disk",
  ...

To set the environment variable use;

bash> FACTERDB_INJECT_SOURCE='true'

or on Windows

powershell> $ENV:FACTERDB_INJECT_SOURCE = 'true'
