ServiceStage
User Guide	2 Permissions Management

2Permissions Management

Creating a User and Granting Permissions

Creating a Custom Policy

Assigning Permissions on Services that ServiceStage Depends On

2.1 Creating a User and Granting Permissions

This section describes how to use IAM to implement fin	n permissions
control for your ServiceStage resources. With IAM, you can:

●Create IAM users for employees based on the organizational structure of your enterprise. Each IAM user has their own security credentials, providing access to ServiceStage resources.

●Grant only the permissions required for users to perform a task.

● Entrust a HUAWEI CLOUD account or cloud service to perform ffic n O&M on your ServiceStage resources.

If your HUAWEI CLOUD account does not require individual IAM users, skip this section.

This section describes the procedure for granting permissions (see Figure 2-1).

Prerequisites

Before assigning permissions to user groups, you should learn about the ServiceStage permissions listed in Permissions Management. For the system policies of other services, see System Permissions.

Issue 01 (2021-04-06)

ServiceStage
User Guide	2 Permissions Management

Process Flow

Figure 2-1 Process for granting ServiceStage permissions

1.Create a user group and grant permissions to it.

Create a user group on the IAM console, and assign the ServiceStage ReadOnlyAccess policy to the group.

2.Create a user.

Create a user on the IAM console and add the user to the group created in 1.

3.Log in and verify permissions.

– Select ServiceStage from Service List. Choose Application Management

> Application List from the navigation tree. On the page that is

displayed, click Create Application. If a message appears indicating

nffic n permissions to access the service, the ServiceStage

ReadOnlyAccess policy has already taken ff c

–Choose any other service in the Service List. If a message appears

indicating n ffic n permissions to access the service, the ServiceStage ReadOnlyAccess policy has already taken ff c

2.2 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.

Issue 01 (2021-04-06)

ServiceStage
User Guide	2 Permissions Management
	● JSON: Edit JSON policies 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 modify a microservice engine.

{

"Version": "1.1", "Statement": [

{

"Action": [ "cse:*:*"

ff c "Allow"

{

"Action": [ "cse:engine:create", "cse:engine:delete"

ff c "Deny"

}

]

}

A deny policy must be used in conjunction with other policies to take ff c 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 are the steps to be performed on the console.

1.Log in to HUAWEI CLOUD as an IAM user.

– Account name: Name of the account used to create the IAM user

– Username and password: Username and password	c fi for the IAM
user

2.On the ServiceStage console, choose Infrastructure > Cloud Service Engines, and buy a microservice engine. If error 403 is returned, the permissions are correct and have already taken ff c

2.3Assigning Permissions on Services that ServiceStage Depends On

Granting CCE Namespace Permissions

You can grant only common operation permissions on CCE cluster resources to the ServiceStage user group using IAM, excluding the namespace permissions of the clusters with Kubernetes RBAC authentication enabled. Therefore, you need to separately grant the namespace permissions for the clusters.

Issue 01 (2021-04-06)

ServiceStage
User Guide	2 Permissions Management
	For details about how to set CCE namespace permissions, see Permissions
	Management.

Granting CTS Permissions

Currently, Cloud Trace Service (CTS) does not support fin n authorization. After the permissions are set for ServiceStage using IAM, they do not take ff c for the CTS service on which ServiceStage depends. You need to set the CTS service permissions separately.

For details about how to set CTS namespace permissions, see Permissions Management.

3.1 Creating an Application

An application is a service system with functions and consists of one or more application components.

For example, the weather forecast is an application that contains the weather and forecast components. ServiceStage organizes multiple components by application, and supports dark launch and quick cloning of applications in ff n environments.

Creating an Application

Step 1 Log in to ServiceStage and choose Application Management > Application List.

Step 2 Click Create Application and set basic application information.

1.Name: Enter an application name. This name cannot be changed after the application is created.

2.Enterprise Project: Set an enterprise project.

Enterprise projects provide a cloud resource management mode, in which cloud resources and members are centrally managed by project.

It is available after the enterprise center is enabled.

Adding Environment Variables

An environment is a collection of infrastructures, covering computing, storage, and networks, used for application deployment and running. ServiceStage combines basic resources (such as CCE and ECS) and optional resources (such as ELB, RDS, and DCS) in the same VPC into an environment, such as the development environment, testing environment, pre-production environment, and production environment. Networks in an environment can communicate with each other. You can manage resources and deploy services by environment, simplifying infrastructure O&M.

Environment variables are parameters set in the system or user applications. You can obtain the values of environment variables by calling APIs. During deployment, parameters are c fi through environment variables instead of in the code, which makes the deployment fl x b

Step 1 Log in to ServiceStage and choose Application Management > Application List.

Step 2 Click the application name. The Overview page is displayed.

Step 3 Click Environment Variables and select a created environment from the Environment drop-down list.

Step 4 Click Add Environment Variable and enter the values in Key and Value.

Key indicates the name of the environment variable, and Value indicates the value of the environment variable. Click Submit.

For example, set Key to User and Value to admin. That is, when the program code reads the User environment variable, admin is obtained. For example, you can start subprocesses as the admin user and read fi as the admin user. The actual execution ff c depends on the code.

----End

3.2 Creating Application Components

3.2.1 Application Components

An application component implements a service feature of an application. It is in the form of code or software packages and can be deployed independently.

After creating an application on ServiceStage, you can add components to the application. Currently, microservice, web, and common application components are supported.

You can create a static component by setting the component type, framework, runtime system, and component source, and then deploy this component.

Issue 01 (2021-04-06)
