# Cluster management project (alpha)
CAUTION: **Warning:**
This is an _alpha_ feature, and it is subject to change at any time without
prior notice.
> [Introduced](https://gitlab.com/gitlab-org/gitlab/issues/32810) in GitLab 12.5
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.
- Any jobs that require `cluster-admin` privileges.
## Permissions
Only the management project will receive `cluster-admin` privileges. All
other projects will continue to receive [namespace scoped `edit` level privileges](../project/clusters/add_remove_clusters.md#rbac-cluster-resources).
Management projects are restricted to the following:
- For project-level clusters, the management project must in the same
namespace (or descendants) as the cluster's project.
- For group-level clusters, the management project must in the same
group (or descendants) as as the cluster's group.
- For instance-level clusters, there are no such restrictions.
## Usage
To use a cluster management project for a cluster:
1. Select the project.
1. Configure your pipelines.
1. Set an environment scope.
### Selecting a cluster management project
To select a cluster management project to use:
1. Navigate to the appropriate configuration page. For a:
- [Project-level cluster](../project/clusters/index.md), navigate to your project's
**Operations > Kubernetes** page.
- [Group-level cluster](../group/clusters/index.md), navigate to your group's **Kubernetes**
page.
1. Select the project using **Cluster management project field** in the **Advanced settings**
section.
### Configuring your pipeline
After designating a project as the management project for the cluster,
write a [`.gitlab-ci,yml`](../../ci/yaml/README.md) in that project. For example:
```yaml
configure cluster:
stage: deploy
script: kubectl get namespaces
environment:
name: production
```
### Setting the environment scope **(PREMIUM)**
[Environment
scopes](../project/clusters/index.md#setting-the-environment-scope-premium)
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 following environments set in
[`.gitlab-ci.yml`](../../ci/yaml/README.md) will deploy to the
Development, Staging, and Production cluster respectively.
```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
```
