Rudder 6.1 release notes

What’s new?

Rudder 6.1 improves and refines the new Rudder 6 features, but also provides major improvements for policy modelization by introducing a new hierarchic property system, extending node properties to global and group properties.

Security-oriented features have been polished, with new operating systems supported in the CIS plugin, redesigned interface for the OpenSCAP plugin and better CVE fetching.

Plugins for IT security

  • CIS policy pack: Allows to apply pre-made CIS policies in one click using Rudder. Now supports Debian 9 and Ubuntu 18.04 LTS in addition to RHEL/CentOS7.

  • CVE management: Reports CVEs affecting installed packages.

  • OpenSCAP: Runs OpenSCAP audits, collects and exposes them in the web interface. The UI has been been redesigned for easier use.

Policy design: Hierarchic properties and improved technique editor

  • In addition to existing node properties, we added group properties, and improved global parameters. This allows powerful hierarchic variable definition, with easy overrides.

  • Several improvements for techniques created with the technique editor:

    • Technique description is now rendered as markdown in the directive form, allowing to document the technique for its users.

    • The technique parameter now have a description field, to help the user fill the form, like already existed for build-in techniques.

    • You can chose the category you put your techniques in directly from the editor.

  • New generic methods for file edition using Augeas.

User experience improvements

  • The groups page has been redesigned with a much cleaner interface.

  • In node details, the system policies have moved from the "Compliance" to a a new "System status" tab for improved readability.

  • The resource manager in the technique editor has been improved.

  • New useful commands:

    • rudder server create-user to create admin users,

    • rudder agent policy-server to manage an agent’s policy server.


  • The API documentation has been migrated to OpenAPI and its content was updated and improved.

  • The navigation of the documentation has been improved to provide easier access to Rudder resources.

  • A brand new page for variables management.


  • The local passwords are now hashed with bcrypt by default.

  • There is now no default admin account after installation (but a new rudder server create-user command allows easily creating local users).

  • HTTPS reporting is now available in changes-only mode, and for Windows agents. Syslog reporting mechanism is now deprecated, and will be removed in a future major release.

  • The first part of the Rudder language infrastructure is added to 6.1, but not visible to users for now. Our goal is to test existing configuration parsing and migration to prepare the future switch of configuration format.

  • jq is now available on all agents to allow easy JSON manipulation.

  • The technique editor is not a separate application anymore, but becomes a part of the main web application.
