GitLab Clusters API
> [!warning] > These certificate-based cluster endpoints are [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/work_items/8). Use this API to manage and discover the certificate-based Kubernetes clusters of an [instance](https://docs.gitlab.com/user/instance/clusters/), a [group](https://docs.gitlab.com/user/group/clusters/), or a [project](https://docs.gitlab.com/user/project/clusters/). Connecting a cluster to a group or an instance lets you use the same cluster across multiple projects. Instance endpoints require administrator access. Group and project endpoints require the Maintainer or Owner role.
