Foreman plugin adds Proxmox VE compute resource using fog-proxmox. It is compatible with Foreman 1.22+



 Project Readme


CI Maintainability Test Coverage Gem Version


Foreman plugin that adds Proxmox compute resource: managing virtual machines and containers using the fog-proxmox module.

It is intended to satisfy this feature.

If you like it and need more features you can contribute or simply support it:


You can support the plugin development via the following methods:

From OS packages (required)

Please see the Foreman manual for complete instructions:

Install from package is the easiest way to install the plugin. Choose the latest release plugins repository. If you don't find it in the same foreman release repository, get it from the nightly repository.

Then you can install it with the package manager, in Debian/Ubuntu:

sudo apt-get install ruby-foreman-fog-proxmox

and in Fedora/Redhat Linux:

sudo dnf install rubygem-foreman_fog_proxmox

Redhat, CentOS or Fedora users should also setup Selinux to allow foreman and all its plugins to work.

From gem

See complete details in plugin installation from gem

Here is a Debian sample:

sudo apt install -y foreman foreman-pgsql
  • Use only foreman user (not root!) sudo -u foreman ...
  • In /usr/share/foreman/bundler.d directory, add Gemfile.local.rb file and add this line in it:
echo "gem 'foreman_fog_proxmox'" | sudo -u foreman tee /usr/share/foreman/bundler.d/Gemfile.local.rb
  • Install the gem plugin:
sudo -u foreman /usr/bin/foreman-ruby /usr/bin/bundle install
  • Precompile plugin assets:

You need nodejs installed in order to use foreman-assets package.

/usr/bin/foreman-ruby /usr/bin/bundle exec bin/rake plugin:assets:precompile[foreman_fog_proxmox]
  • Compile plugin translations if (french) needed :
/usr/bin/foreman-ruby /usr/bin/bundle exec bin/rake plugin:gettext[foreman_fog_proxmox]
  • Complete installation of foreman 1.22 with foreman-installer:
sudo apt install -y foreman-installer
sudo foreman-installer

If you don't want to have HTTP 503 errors when apt is trying to install puppetserver, then add this before launching foreman-installer:

echo 'Acquire::http::User-agent "Mozilla/5.0 (Linux)";' | sudo tee /etc/apt/apt.conf.d/96useragent

See complete details in plugin installation from gem

Then you can check plugin installation after login into your new foreman server seeing the about foreman page:

Dev prerequisites

See Foreman dev setup

  • You need a Proxmox VE 6.2+ server running.
  • You need ruby 2.7. You can install it with asdf-vm.
  • You also need nodejs 14 in your dev machine to run webpack-dev-server. You can install it with asdf-vm.


  • Fork this github repo.
  • Clone it on your local machine
  • Install foreman v2.5+ on your machine:
git clone https://github.com/theforeman/foreman -b develop
  • Create a Gemfile.local.rb file in foreman/bundler.d/
  • Add this line:
gem 'foreman_fog_proxmox', :path => '../../theforeman/foreman_fog_proxmox'
gem 'fog-proxmox', :path => '../../fog/fog-proxmox' # optional if you need to modify fog-proxmox code too
gem 'ruby-debug-ide' # dev
gem 'debase' # dev
gem 'solargraph' # dev
gem 'simplecov' # test
  • In foreman directory, install dependencies:
gem install bundler
# prerequisites libraries on Ubuntu OS:
# sudo apt install postgresql-client-13 libpq-dev libsystemd-dev
bundle config set without 'libvirt ovirt'
bundle install
npm install
  • Configure foreman settings:
cp config/settings.yaml.test config/settings.yaml

add these lines to config/settings.yml:

    :webpack_dev_server: true
    :destroy_vm_on_host_delete: true # optional, could be set on UI
      :level: debug
       :enabled: false
  • SQLite is no more default rails dev or test database, instead add:
  • (Optional) test and dev with postgresql database:
cp config/database.yml.example config/database.yml

add these lines to each environment in config/database.yml:

    host: localhost
    username: foreman
    password: foreman
cp config/ignored_environments.yml.sample config/ignored_environments.yml
docker run --name foreman-db -v foreman_data:/var/lib/postgresql/data -e POSTGRES_DB=foreman -e POSTGRES_USER=foreman -e POSTGRES_PASSWORD=foreman -p 5432:5432 -d postgres:13
bundle exec bin/rake db:migrate
RAILS_ENV=development bundle exec bin/rake db:seed assets:precompile locale:pack webpack:compile
  • You can reset and change your admin password if needed:
RAILS_ENV=development bundle exec bin/rake permissions:reset password=changeme
  • You should write tests and you can execute those specific to this plugin:

first, create database foreman-test:

RAILS_ENV=test bundle exec rake db:create

then add test schema and seeds:

RAILS_ENV=test bundle exec bin/rake db:migrate
RAILS_ENV=test bundle exec bin/rake db:seed

Finally you can test all:

export DISABLE_SPRING=true
bundle exec bin/rake test:foreman_fog_proxmox

or just one:

export DISABLE_SPRING=true
bundle exec bin/rake test TEST=../foreman_fog_proxmox/test/functional/compute_resources_controller_test.rb DATABASE_URL=nulldb://nohost
  • In foreman_fog_proxmox source directory, check code syntax with rubocop and foreman rules:
bundle exec rubocop

safe autocorrect:

bundle exec rubocop -a

Temporary ignore offenses:

bundle exec rubocop --auto-gen-config
  • See deface overrides result:
bundle exec bin/rake deface:get_result['hosts/_compute_detail']
  • In foreman directory, after you modify foreman_fog_proxmox specific assets (proxmox.js, etc) you have to precompile it:
bundle exec bin/rake plugin:assets:precompile[foreman_fog_proxmox]
  • In foreman directory, after you modify foreman_fog_proxmox translations (language, texts in new files, etc) you have to compile it:

Prerequisites: Transifex CLI

bundle exec bin/rake plugin:gettext\[foreman_fog_proxmox\]
  • In foreman directory, run in a new terminal the webpack-dev-server:
./node_modules/.bin/webpack-dev-server-without-h2 --config config/webpack.config.js
  • Or without webpack-dev-server, add this line in config/settings.yml:
:webpack_dev_server: false

then compile webpack assets:

bundle exec bin/rake webpack:compile
  • In foreman directory, run rails server:
bundle exec bin/rails server
  • Or you can launch all together:
bundle exec foreman start
