Creating a Custom Policy

Custom policies can be created as a supplement to the system policies of ServiceStage.

You can create custom policies in either of the following ways:

  • Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
  • JSON: Create a policy in the JSON format from scratch or based on an existing policy.

For details, see Creating a Custom Policy. The following section contains examples of common ServiceStage custom policies.

Example Custom Policy

This procedure creates a policy that an IAM user is prohibited to create and delete a microservice engine.
        "Version": "1.1",
        "Statement": [
                        "Action": [
                        "Effect": "Allow"
                        "Action": [
                        "Effect": "Deny"

A deny policy must be used in conjunction with other policies to take effect. If the permissions assigned to a user contain both "Allow" and "Deny", the "Deny" permissions take precedence over the "Allow" permissions.

After authorization, users in the group can verify their permissions using the console or REST APIs.

The following uses the custom policy as an example to describe how to log in to the ServiceStage console to verify that a user is not allowed to create microservice engines.

  1. Log in to Huawei Cloud as an IAM user.
    • Tenant name: Name of the Huawei Cloud account used to create the IAM user
    • IAM username and password: Username and password specified during the IAM user creation using the tenant name
  2. On the Cloud Service Engines page, create a microservice engine. If error 403 is returned, the permissions are correct and have taken effect.
