Assign a Cluster to Multiple Workspaces (Tenants)¶

Cluster resources are typically managed by operations personnel. When allocating resources, they need to create namespaces to isolate resources and set resource quotas. This method has a drawback: if the business volume of the enterprise is large, manually allocating resources requires a significant amount of work, and flexibly adjusting resource quotas can also be challenging.

To address this, DCE introduces the concept of workspaces. By sharing resources, workspaces can provide higher-dimensional resource quota capabilities, allowing workspaces (tenants) to self-create Kubernetes namespaces under resource quotas.

For example, if you want several departments to share different clusters:

You can follow the process below to share clusters with multiple departments/workspaces/tenants:

graph TB

preparews[Prepare Workspace] --> preparecs[Prepare Cluster]
--> share[Share Cluster to Workspace]
--> judge([Judge Workspace Remaining Quota])
judge -.Greater than remaining quota.->modifyns[Modify Namespace Quota]
judge -.Less than remaining quota.->createns[Create Namespace]

Prepare a Workspace¶

Workspaces are designed to meet multi-tenant usage scenarios, forming isolated resource environments based on clusters, cluster namespaces, meshes, mesh namespaces, multicloud, multicloud namespaces, and other resources. Workspaces can be mapped to various concepts such as projects, tenants, enterprises, and suppliers.

1. Log in to DCE 5.0 with a user having the admin/folder admin role and click Global Management at the bottom of the left navigation bar.

   

2. Click Workspaces and Folders in the left navigation bar, then click the Create Workspace button at the top right.

   

3. Fill in the workspace name, folder, and other information, then click OK to complete the creation of the workspace.

   

Prepare a Cluster¶

Workspaces are designed to meet multi-tenant usage scenarios, forming isolated resource environments based on clusters, cluster namespaces, meshes, mesh namespaces, multicloud, multicloud namespaces, and other resources. Workspaces can be mapped to various concepts such as projects, tenants, enterprises, and suppliers.

Follow these steps to prepare a cluster.

1. Click Container Management at the bottom of the left navigation bar, then select Clusters .

   

2. Click Create Cluster to create a cluster or click Integrate Cluster to integrate a cluster.

Add Cluster to Workspace¶

Return to Global Management to add clusters to the workspace.

1. Click Global Management -> Workspaces and Folders -> Shared Resources, then click a workspace name and click the New Shared Resource button.

   

2. Select the cluster, fill in the resource quota, and click OK .

   

Next Step: After allocating cluster resources to multiple workspaces, users can go to Workbench to create namespaces and deploy applications in these workspaces.
