Foreman Datacenter Plugin

This plugin lets you document your physical servers across multiple datacenters. It documents racks, devices, interfaces, connections between machines (servers or switches).

Foreman Datacenter plugin documents following:

  • Sites - contains all physical locations (datacenters) where servers are stored
  • Racks - contains all racks across all datacenters
  • Rack groups - group of racks, e.g. one room where this group of racks is stored
  • Devices - contains all devices (switches, servers, etc.)
  • Device types - contains all device types (e.g. HP ProLiant DL180 G6)
  • Device roles - e.g. server, switch, etc.
  • Manufacturers - contains all manufacturers (HP, Dell, etc.)
  • Platforms - e.g. ipmi, mgmt interface, etc.
  • Console connections - lists all e.g. RS232 connections
  • Power connections - lists all connections of power cables
  • Interface connections - lists all connections between interfaces

Installation by package

See Plugins Installation for how to install Foreman plugins.

Ubuntu/Debian instructions

apt-get install ruby-foreman-datacenter

Redhat/Centos instructions

Note the package hasn't actually been created yet.

yum install tfm-rubygem-foreman_datacenter

Installation by gem

Redhat/Centos instructions (confirmed on Katello 3.4/Foreman 1.15.6 and 1.16)

You may need to install additional Gems and feed db:

# Install some required gems for precompile assets
gem install --ignore-dependencies sprockets
gem install --ignore-dependencies sass
gem install --ignore-dependencies sass-listen
gem install --ignore-dependencies rb-fsevent
gem install --ignore-dependencies rb-inotify
gem install --ignore-dependencies ffi

# Add repo cause ffi needs ruby22-ruby-devel
cat > /etc/yum.repos.d/CentOS-SCLo-scl.repo << EOF
name=CentOS-7 - SCLo sclo ruby22

# Install ruby22-ruby-devel for ruby gem ffi
yum install rh-ruby22-ruby-devel
gem install --ignore-dependencies ffi

# Precompile assets should work now
foreman-rake assets:precompile

# Now feed database
RAILS_ENV=production rake db:migrate

# If it fails
cd /opt/rh/rh-ruby22/root/usr/local/share/gems/gems/foreman_datacenter-0.1.49/db/migrate
for F in `ls`;do  sed -i ${F} -e 's/\[4.2\]//';done;


Create a device type

Here you can create a particular device type, for example a model of switch and then create all interfaces only here, so when you create a particular switch, it will have all the desired interfaces. Just click on Device types -> New device type, fill in information and save. Then click on the desired device type and you can add all the interfaces here.

Create a device

You can either just create a device - then you have to create first Manufacturer, Device Type, Device Role, Platform; or you can import device from Puppet facts (this feature is still in development phase) - you just click Devices -> Import from host and then will search your host and click Import to device. Then you will get a page with additional information about the machine to be filled like location, position in rack, etc. Once device is created, you can list it in Devices section and when you click on this device, you can fill in additional information, e.g. connect its interfaces to a switch, etc.


Sometimes you may encounter a problem that does not work dropdown select field(like this #12 or this #9)

Please make assets precompilation manually as following in foreman installation dir:

foreman-rake assets:precompile

We are working on this problem
