Cluster levels (deprecated)

History

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:

  1. On the left sidebar, select Search or go to and find your project.
  2. Select Operate > Kubernetes clusters.

Group-level clusters:

  1. On the left sidebar, select Search or go to and find your group.
  2. Select Operate > Kubernetes clusters.

Instance-level clusters:

  2. Select Kubernetes.

Security implications for clusters connected with certificates

History

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.
