What is Management Mode?

Runner management mode is a standalone process that is deployed first in an install’s runner VM. Once it has started, it is responsible for configuring, starting, monitoring, and updating a child runner process for the install itself. This install runner process then carries out all of the day to day runner operations. This allows for an additional degree of flexibility when managing updates and paves the way for future runner features. This release introduces runner management mode into GA as an opt-in feature which can be enabled by configuring the init_script_url attribute in runner.toml in the app config. We recommend all new installs make use of it from day-1.

​
Migrating an existing Install

  1. Update runner.toml to use the management mode init script.
runner.toml
init_script_url = "https://raw.githubusercontent.com/nuonco/runner/refs/heads/main/scripts/aws/init-mng.sh"
  1. Update stack.toml to use the 1.6 version of the Runner ASG nested CF stack runner_nested_template_url.
stack.toml
runner_nested_template_url = "https://nuon-artifacts.s3.us-west-2.amazonaws.com/aws-cloudformation-templates/v0.1.6/runner/asg/stack.yaml"
  1. Sync the app config with nuon apps sync
  2. Reprovision the install and apply the new stack as a CF change-set.
