Foreman is a free open source project that gives you the power to easily automate repetitive tasks, quickly deploy applications, and proactively manage your servers lifecyle, on-premises or in the cloud.

From provisioning and configuration to orchestration and monitoring, Foreman integrates with your existing infrastructure to make operations easier.

Using Puppet, Ansible, Chef, Salt and Foreman's smart proxy architecture, you can easily automate repetitive tasks, quickly deploy applications, and proactively manage change, both on-premise with VMs and bare-metal or in the cloud.

Foreman provides comprehensive, interaction facilities including a web frontend, CLI and RESTful API which enables you to build higher level business logic on top of a solid foundation.

Foreman is a mature project, deployed in many organizations, managing from 10s to 10000s of servers. It is used in distributions such as RDO and RHOS (Red Hat OpenStack distribution) and has an extensive library of plugins.


  • Automate your mixed infrastructure to make operations enjoyable
  • Discover, provision and upgrade your entire bare-metal infrastructure
  • Create and manage instances across private and public clouds
  • Group your hosts and manage them in bulk, regardless of location
  • Review historical changes for auditing or troubleshooting
  • Extend as needed via a robust plugin architecture
  • Automatically build images (on each platform) per system definition to optimize deployment
  • LDAP authentication and RBAC authorization to your infrastructure
  • and so much more

Read the quickstart section of the manual. If you know your setup has some specific needs, read the installation scenarios section.


Our main documentation reference is the Foreman manual. If you find some gaps you would like to fill in the manual, please contribute in this repo.


We document our API using apipie.The API chapter has more information about accessing the API and the layout of requests and responses. Also see the reference documentation available on our website, or via your own Foreman installation by appending /apidoc to the URL to see the API routes available.


Plugins are tools to extend and modify the functionality of Foreman. They are implemented as Rails engines that are packaged as gems and thus easily installed into Foreman.

The plugins page lists all available plugins and has more information about how to install and develop them.
