The new plugin ecosystem in RUDDER 5.0

The latest major version of the solution has brought a major new feature to the Rudder solution: a plugin ecosystem.

The Rudder software architect will present the reasons for this new feature, how it works, and what are the different plugins available.

  1. The new plugin ecosystem in RUDDER 5.0 CONTINUOUS AUDITING &

  2. PLUGINS 1. What are plugins 2. How plugins work a.

    Package, Install remove b. Compatibility c. Licences 2
  3. PLUGINS what • An extension of Rudder • Put into

    a package (and RPKG file) • Installable on the server or on relays ◦ All plugins are for the server currently ◦ If something is needed on the agent, it will be installed by the server • Can extend anything 3
  4. 4 4 Root Server Relay Server SERVER & AGENT Node

    AGENT Node AGENT Node AGENT Private network Integration plugin Package.rpkg Third party Webapp Feature plugin Feature plugin Integration plugin
  5. PLUGINS Under the hood A bit like deb files: ar

    file containing everything • The metadata contains package information • A script.txz files that contains script for pre and post install • All files in a files.txz archive We use this for seamless installation We make plugins that do not break everything when they are disabled. 5
  6. PLUGINS Under the hood Packages are generated from our plugin

    repo, but you can write your own Packages are installed with “rudder-pkg install-file” command Dependencies are not automatically installed (at the moment) but are displayed so the user can do it 6
  7. PLUGINS Versioning Plugin versions : <rudder_makor>-<major>.<minor> Example: myplugin 5.0-1.1 ▪

    The first part indicates the compatibility of the plugin with Rudder ▪ The second part is the real version of the plugin. Plugin version does not change with rudder version, example: • centreon 4.3-1.0 • centreon 5.0-1.0 Same plugin, different build. 7
  8. PLUGINS Licences Some plugins are completely free (GPLv2) • Integration

    plugins for free software are free • Rudder common features stay free Some plugins are not • Integration plugin with proprietary tools • Support for proprietary OS • Plugins that extend Rudder in a way that only big players may consider 8
  9. PLUGINS Licenses Plugins that are not free need a license

    to work properly. To install a license • Get a subscription from Rudder • We provide you with the binary package for the plugin • We provide you the license and doc to install it Come and see us! 9
  10. PLUGINS A note about the repository Base URl is now

    https://repository.rudder.io/ It contains everything that can be downloaded: ▪ Packages ▪ Plugins ▪ Sources ▪ Build dependencies 10
  11. PLUGINS Feature plugins 1. Reporting 2. Customization 3. Access right

    management (web + api) 4. Validation workflow 5. Datasource 6. Relay 7. External authentication 11
  12. PLUGINS Reporting Reporting plugin : • Reports on past data

    • Keep history of the compliance of your fleet • Create archive reports • Reports that can be exported to PDF • Reports based on your needs 12

  16. PLUGINS Access Rights Splitted in 2 plugins : • Give

    access rights to people • Give access rights to scripts • Rights for using the interface • Rights for calling the API 16
  17. PLUGINS Workflow AKA change requests: ▪ Validate change before they

    go into production ▪ For having two pairs of eyes ▪ For new people in the team 17
