# Connect a cluster to GitLab **(FREE)**
2021-12-11 22:18:48 +05:30
The [certificate-based Kubernetes integration with GitLab ](../index.md )
was [deprecated ](https://gitlab.com/groups/gitlab-org/configure/-/epics/8 )
2022-05-07 20:08:51 +05:30
in GitLab 14.5. To connect your clusters, use the [GitLab agent ](../../../clusters/agent/index.md ).

## Cluster levels (DEPRECATED)
> [Deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5.
WARNING:
The [concept of cluster levels was deprecated ](../index.md#cluster-levels )
in GitLab 14.5.
2021-11-18 22:05:49 +05:30
Choose your cluster's level according to its purpose:
| Level | Purpose |
|--|--|
| [Project level ](../../../project/clusters/index.md ) | Use your cluster for a single project. |
| [Group level ](../../../group/clusters/index.md ) | Use the same cluster across multiple projects within your group. |
| [Instance level ](../../../instance/clusters/index.md ) | Use the same cluster across groups and projects within your instance. |
### View your clusters
2021-11-11 11:23:49 +05:30
To view the Kubernetes clusters connected to your project,
2021-11-18 22:05:49 +05:30

## Security implications for clusters connected with certificates
2021-12-11 22:18:48 +05:30
> Connecting clusters to GitLab through cluster certificates was [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5.
2021-11-11 11:23:49 +05:30
WARNING:
The whole cluster security is based on a model where [developers ](../../../permissions.md )
are trusted, so **only trusted users should be allowed to control your clusters** .
The use of cluster certificates to connect your cluster grants
access to a wide set of functionalities needed to successfully
build and deploy a containerized application. Bear in mind that
the same credentials are used for all the applications running
on the cluster.
