The certificate-based integration with Kubernetes [will be deprecated and removed](https://about.gitlab.com/blog/2021/11/15/deprecating-the-cert-based-kubernetes-integration/).
As a self-managed customer, we are introducing the [feature flag](../administration/feature_flags.md#enable-or-disable-the-feature) `certificate_based_clusters` in GitLab 15.0 so you can keep your certificate-based integration enabled. However, the feature flag will be disabled by default, so this change is a **breaking change**.
In GitLab 17.0 we will remove both the feature and its related code. Until the final removal in 17.0, features built on this integration will continue to work, if you enable the feature flag. Until the feature is removed, GitLab will continue to fix security and critical issues as they arise.
