[!warning] The concept of cluster levels was deprecated in GitLab 14.5.
Choose your cluster's level according to its purpose:
| Level | Purpose |
|---|---|
| Project level | Use your cluster for a single project. |
| Group level | Use the same cluster across multiple projects within your group. |
| Instance level | Use the same cluster across groups and projects within your instance. |
To view the Kubernetes clusters connected to your project, group, or instance, open the cluster's page according to your cluster's level.
Project-level clusters:
Group-level clusters:
Instance-level clusters:

[!warning] The whole cluster security is based on a model where developers 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.
