Using IAM Identity Policies to Grant Access to LTS

System-defined permissions in "Identity Policy-based Authorization" provided by Identity and Access Management (IAM) let you control access to LTS. With IAM, you can:

  • Create IAM users or user groups for personnel based on your enterprise's organizational structure. Each IAM user has their own identity credentials for accessing LTS resources.
  • Grant users only the permissions required to perform a given task based on their job responsibilities.
  • Entrust a Huawei Cloud account or a cloud service to perform efficient O&M on your LTS resources.

If your Huawei Cloud account meets your permissions requirements, you can skip this section.

Figure 1 shows the process flow of identity policy-based authorization.

Prerequisites

Before granting permissions, learn about system-defined permissions in Identity Policy-based Authorization for LTS. To grant permissions for other services, learn about all system-defined permissions supported by IAM.

Process Flow

Figure 1 Process of granting LTS permissions using identity policy-based authorization
  1. On the IAM console, create an IAM user or create a user group.
  2. Attach a system-defined identity policy (LTS ReadOnlyAccess as an example) to the user or user group.

    Assign the permissions defined in the system-defined identity policy LTS ReadOnlyAccess to the user or group, or attach the system-defined identity policy to it.

  3. Log in as the IAM user and verify permissions.

    In the authorized region, perform the following operations:

    • Choose Service List > Log Tank Service. On the Log Management page displayed, if you can view LTS data but cannot create log groups, the LTS ReadOnlyAccess policy is in effect.
    • Choose another service from Service List. If a message appears indicating that you have insufficient permissions to access the service, the LTS ReadOnlyAccess policy is in effect.

Example Custom Identity Policies

You can create custom identity policies to supplement the system-defined identity policies of LTS. For details about actions supported in custom identity policies, see Log Tank Service API Reference > "Permissions and Supported Actions" > "Actions Supported by identity Policy-based Authorization."

To create a custom identity policy, choose either visual editor or JSON.

  • Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy grammar.
  • JSON: Create a JSON policy or edit an existing one.

For details, see Creating a Custom Identity Policy and Attaching It to a Principal.

The following lists examples of common LTS custom identity policies.

  • Example 1: Grant permission to create and delete log groups. 
    {
    "Version": "5.0",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "lts:logGroup:createLogGroup",
                "lts:logGroup:deleteLogGroup"
            ]
        }
    ]
}
  • Example 2: Create a custom identity policy containing multiple actions.

    A custom identity policy can contain the actions of one or more services. Example identity policy containing multiple actions:

    {
    "Version": "5.0",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "lts:logGroup:createLogGroup",
                "lts:logGroup:deleteLogGroup"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "ecs:cloudServers:listServersDetails"
            ]
        }
    ]
}
