Autoscaled gl runners vs prefixed authentication token

Hi,

Current setup:

  1. gitlab-runner (config.toml) + docker-machine for provisioning GitLab group runners
  2. I am currently using the registration token for all group GitLab runners

As we know, the registration token will be deprecated on May 22, 2024. I have read this documentation, but I’m not sure how to register new GitLab runners after May 22, 2024, and what kind of token I should use. Our GitLab runners aren’t created manually, so how can I obtain authentication tokens?

Please let me know if there is any documentation that explains how to update the configuration for gitlab-runner.

Thank you!
