Why Is "Error from server (Forbidden)" Displayed When I Use kubectl?

Symptom

When you use kubectl to create or query Kubernetes resources, the following output is returned:

# kubectl get deploy Error from server (Forbidden): deployments.apps is forbidden: User "0c97ac3cb280f4d91fa7c0096739e1f8" cannot list resource "deployments" in API group "apps" in the namespace "default"

Possible Cause

This user has no permissions to operate Kubernetes resources.

Solution

Assign permissions to the user.

1. Log in to the CCE console. In the navigation pane, choose Permissions.
2. Select a cluster for which you want to add permissions from the drop-down list on the right.
3. Click Add Permissions in the upper right corner.
4. Confirm the cluster name and select the namespace to assign permissions for. For example, select All namespaces, the target user or user group, and select the permissions.
   

   If you do not have IAM permissions, you cannot select users or user groups when configuring permissions for other users or user groups. In this case, you can enter a user ID or user group ID.

   Permissions can be customized as required. After selecting Custom for Permission Type, click Add Custom Role on the right of the Custom parameter. In the dialog box displayed, enter a name and select a rule. After the custom rule is created, you can select a value from the Custom drop-down list box.

   Custom permissions are classified into ClusterRole and Role. Each ClusterRole or Role contains a group of rules that represent related permissions. For details, see Using RBAC Authorization.

   • A ClusterRole is a cluster-level resource that can be used to configure cluster access permissions.
   • A Role is used to configure access permissions in a namespace. When creating a Role, specify the namespace to which the Role belongs.

5. Click OK.
