Release Notes

Automation Controller Version 4.1

Introduced

  • Connected Receptor nodes to form a control plane and execution mesh configurations

  • The special controlplane instance group to allow for the task manager code to target an OpenShift Controller node to run the project update

  • The ability to render a configured mesh topology in a graph in the installer

  • Controller 4.1 execution nodes can be remote

  • Node types for Controller 4.1 (control, hybrid, execution, hop, control, hybrid, execution, hop) installed for different sets of services and provide different capabilities, allowing for scaling nodes that provide the desired capability such as job execution or serving of web requests to the API/UI.

Added

  • The ability for the platform installer to allow users to install execution nodes and express receptor mesh topology in the inventory file. The platform installer will also be responsible for deprovisioning nodes.

  • Work signing to the receptor mesh so that control plane nodes have the exclusive authority to submit receptor work to execution nodes over the mesh

  • Support for pre-population of execution environment name, description, and image from query parameters when adding a new execution environment in the Controller User Interface

  • Ability to trigger a reload of the topology configuration in Receptor without interrupting work execution

  • Using Public Key Infrastructure (PKI) for securing the Receptor mesh

  • Added importing execution environments from Automation Hub into the controller to improve the platform experience

Updated

  • The controller to support new controller control plane and execution mesh

  • Task manager will only run project updates and system jobs on nodes with node_type of “control” or “hybrid”

  • Task manager will only run jobs, inventory updates, and ad hoc commands on nodes with node_type of “hybrid” or “execution”

  • Heartbeat and capacity check to work with Receptor execution nodes

  • Reaper to work with the addition of execution nodes

  • Controller User Interface to not show control instances as an option to associate with instance groups

  • The Associate pop-up screen to display host names when adding an existing host to a group

  • Validators for editing miscellaneous authentication parameters

  • Advanced search key options to be grouped

  • SAML variables default values

  • Survey validation on Prompt on Launch

  • Login redirect
