# Cluster management project (deprecated)
DETAILS:
**Tier:** Free, Premium, Ultimate
**Offering:** GitLab.com, Self-managed, GitLab Dedicated
> - [Disabled on self-managed](https://gitlab.com/gitlab-org/gitlab/-/issues/353410) in GitLab 15.0.
WARNING:
The cluster management project was [deprecated](https://gitlab.com/groups/gitlab-org/configure/-/epics/8) in GitLab 14.5.
To manage cluster applications, use the [GitLab agent](agent/index.md)
with the [Cluster Management Project Template](management_project_template.md).
FLAG:
On self-managed GitLab, by default this feature is not available. To make it available, an administrator can [enable the feature flag](../../administration/feature_flags.md) named `certificate_based_clusters`.
A project can be designated as the management project for a cluster.
A management project can be used to run deployment jobs with
Kubernetes
[`cluster-admin`](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#user-facing-roles)
privileges.
This can be useful for:
- Creating pipelines to install cluster-wide applications into your cluster, see [management project template](management_project_template.md) for details.
- Any jobs that require `cluster-admin` privileges.
## Permissions
Only the management project receives `cluster-admin` privileges. All
other projects continue to receive [namespace scoped `edit` level privileges](../project/clusters/cluster_access.md#rbac-cluster-resources).
Management projects are restricted to the following:
- For project-level clusters, the management project must be in the same
namespace (or descendants) as the cluster's project.
- For group-level clusters, the management project must be in the same
group (or descendants) as the cluster's group.
- For instance-level clusters, there are no such restrictions.
## How to create and configure a cluster management project
To use a cluster management project to manage your cluster:
1. Create a new project to serve as the cluster management project
for your cluster.
1. [Associate the cluster with the management project](#associate-the-cluster-management-project-with-the-cluster).
1. [Configure your cluster's pipelines](#configuring-your-pipeline).
1. [Set the environment scope](#setting-the-environment-scope).
### Associate the cluster management project with the cluster
To associate a cluster management project with your cluster:
1. Go to the appropriate configuration page. For a:
- [Project-level cluster](../project/clusters/index.md), go to your project's
**Operate > Kubernetes clusters** page.
- [Group-level cluster](../group/clusters/index.md), go to your group's **Kubernetes**
page.
- [Instance-level cluster](../instance/clusters/index.md):
1. On the left sidebar, at the bottom, select **Admin**.
1. Select **Kubernetes**.
1. Expand **Advanced settings**.
1. From the **Cluster management project** dropdown list, select the cluster management project
you created in the previous step.
### Configuring your pipeline
After designating a project as the management project for the cluster,
add a `.gitlab-ci.yml` file in that project. For example:
```yaml
configure cluster:
stage: deploy
script: kubectl get namespaces
environment:
name: production
```
### Setting the environment scope
[Environment scopes](../project/clusters/multiple_kubernetes_clusters.md#setting-the-environment-scope)
are usable when associating multiple clusters to the same management
project.
Each scope can only be used by a single cluster for a management project.
For example, let's say the following Kubernetes clusters are associated
to a management project:
| Cluster | Environment scope |
| ----------- | ----------------- |
| Development | `*` |
| Staging | `staging` |
| Production | `production` |
The environments set in the `.gitlab-ci.yml` file deploy to the
Development, Staging, and Production cluster.
```yaml
stages:
- deploy
configure development cluster:
stage: deploy
script: kubectl get namespaces
environment:
name: development
configure staging cluster:
stage: deploy
script: kubectl get namespaces
environment:
name: staging
configure production cluster:
stage: deploy
script: kubectl get namespaces
environment:
name: production
```
