Enable KAS
I am trying to connect a GitLab agent in my K8s cluster to my instance, but it appears that KAS is not enabled.

How can this be enabled?
At least now (v14.6.3), you cannot. We have to add configuration support for GitLab KAS (set necessary variables to /assets/runtime/config/gitlabhq/gitlab.yml and /assets/runtime/env-defaults, add description to README.md) . Pull request is welcome :)
Is it safe to update 14->15? How can I enable the certificate_based_clusters feature flag?
Worked fine :)
su - git && cd gitlab
bundle exec rails console -e production
Feature.enable(:certificate_based_clusters)
As #2917 merged, sameersbn/gitlab:16.10.1 or later contains the feature. You may be set GITLAB_FEATURE_FLAGS_DISABLE_TARGETS=certificate_based_clusters.
