Assign the cluster to multiple workspaces (tenants)¶

Cluster resources are usually managed by operation and maintenance personnel. When assigning resource allocations, they need to create namespaces to isolate resources, and set resource quotas. This method has a disadvantage. If the business volume of the enterprise is large, manual allocation of resources requires a large workload, and it is not a small difficulty to flexibly allocate resource quotas.

DCE introduces the concept of workspace for this purpose. Workspaces can provide higher-dimensional resource quota capabilities through shared resources, enabling workspaces (tenants) to self-create Kubernetes namespaces under resource quotas.

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

You can share the cluster with multiple departments/workspace/tenants by following the process:

graph TB

preparews[Prepare workspace] --> preparecs[Prepare cluster]
--> share[Share cluster with workspace]
--> judge([Judge remained quota of workspace])
judge -.More than remained quota.->modifyns[Modify namespace quota]
judge -.Less than remained quota.->createns[Create namespace]

Prepare a workspace¶

In order to meet the multi-tenant use cases, the workspace forms an isolated resource environment based on multiple resources such as clusters, cluster namespaces, meshs, mesh namespaces, multicloud, and multicloud namespaces. Workspaces can be mapped to various concepts such as projects, tenants, enterprises, and suppliers.

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

2. Click Workspace and Folder in the left navigation bar, and click the Create Workspace button in the upper right corner.

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

Prepare a cluster¶

The workspace is to meet the multi-tenant use cases. It forms an isolated resource environment based on multiple resources such as clusters, cluster namespaces, meshs, mesh namespaces, multiclouds, and multicloud namespaces. Workspaces can be mapped to projects and tenants., business, supplier and many other concepts.

Follow the steps below to prepare a cluster.

1. Click Container Management at the bottom of the left navigation bar, and select Cluster List .

2. Click Create Cluster Create a Cluster, or click Join Cluster Join a Cluster.

Add a cluster to the workspace¶

Return to Global Management to add clusters for the workspace.

1. Click Global Management -> Workspace and Folder -> Shared Resources , click a workspace name, and click the New Shared Resource button.

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

Next step: After allocating cluster resources to multiple workspaces, users can go to Workbench under these workspaces create namespace and deploy application.
