     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 GitLab SaaS customer, on new namespaces, you will no longer be able to integrate GitLab and your cluster using the certificate-based approach as of GitLab 15.0. The integration for current users will be enabled per namespace. The integrations are expected to be switched off completely on GitLab SaaS around 2022 November 22.
