Creating a Custom Policy
You can create custom policies to supplement system-defined policies and implement more refined access control.
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 JSON policy or edit an existing one.
Creating a Custom Policy in the Visual Editor
- Log in to the IAM console.
- On the IAM console, choose Permissions > Policies/Roles from the navigation pane, and click Create Custom Policy in the upper right corner.
- Enter a policy name.
- Select Visual editor for Policy View.
- Set the policy content.
- Select Allow or Deny.
- Select a cloud service.
NOTE:
- Only one cloud service can be selected for each permission block. To configure permissions for multiple cloud services, click Add Permissions, or switch to the JSON view (see Creating a Custom Policy in JSON View).
- A custom policy can contain permissions for either global or project-level services. To define permissions required to access both global and project-level services, enclose the permissions in two separate custom policies for refined authorization.
- Select actions.
- (Optional) Select all resources, or select specific resources by specifying their paths.
Table 1 Resource type Parameter
Description
Specific
Permissions for specific resources. For example, to define permissions for buckets whose names start with TestBucket, specify the bucket resource path as OBS:*:*:bucket:TestBucket*.
NOTE:- Specifying bucket resources
Format: "OBS:*:*:bucket:Bucket name".
For bucket resources, IAM automatically generates the prefix of the resource path: obs:*:*:bucket:. For the path of a specific bucket, add the bucket name to the end. You can also use a wildcard character (*) to indicate any bucket. For example, obs:*:*:bucket:* indicates any OBS bucket.
- Specifying object resources
Format: "OBS:*:*:object:Bucket name/object name".
For object resources, IAM automatically generates the prefix of the resource path: obs:*:*:object:. For the path of a specific object, add the bucket name/object name to the end of the resource path. You can also use a wildcard character (*) to indicate any object in a bucket. For example, obs:*:*:object:my-bucket/my-object/* indicates any object in the my-object directory of the my-bucket bucket.
All
Permissions for all resources.
- (Optional) Add request conditions by specifying condition keys, operators, and values.
Table 2 Condition parameters Name
Description
Condition Key
A key in the Condition element of a statement. There are global and service-specific condition keys. Global condition keys (starting with g:) are available for operations of all services, whereas service-specific condition keys (starting with a service abbreviation name such as obs:) are available only for operations of the corresponding service. For details, see the user guide of the corresponding cloud service.
Operator
Used together with a condition key and condition value to form a complete condition statement.
Value
Used together with a condition key and an operator that requires a keyword, to form a complete condition statement.
Table 3 Global condition keys Global Condition Key
Type
Description
g:CurrentTime
Time
Time when an authentication request is received. The time is in ISO 8601 format, for example, 2012-11-11T23:59:59Z.
g:DomainName
String
Account name.
g:MFAPresent
Boolean
Whether to obtain a token through MFA authentication.
g:MFAAge
Number
Validity period of a token obtained through MFA authentication. This condition must be used together with g:MFAPresent.
g:ProjectName
String
Project name.
g:ServiceName
String
Service name.
g:UserId
String
IAM user ID.
g:UserName
String
IAM user name.
- (Optional) Switch to the JSON view and modify the policy content in JSON format.
NOTE:
If the modified policy content is incorrect, check and modify the content again, or click Reset to cancel the modifications.
- (Optional) To add another permission block for the policy, click Add Permissions. Alternatively, click the plus (+) icon on the right of an existing permission block to clone its permissions.
- (Optional) Enter a brief description for the policy.
- Click OK.
- Attach the policy to a user group. Users in the group then inherit the permissions defined in this policy.
NOTE:
You can attach custom policies to a user group in the same way as you attach system-defined policies. For details, see Creating a User Group and Assigning Permissions.
Creating a Custom Policy in JSON View
- Log in to the IAM console.
- On the IAM console, choose Permissions > Policies/Roles from the navigation pane, and click Create Custom Policy in the upper right corner.
- Enter a policy name.
- Select JSON for Policy View.
- (Optional) Click Select Existing Policy/Role and select a policy/role to use it as a template, for example, select EVS Admin.
NOTE:
If you select multiple policies, all of them must have the same scope, that is, either Global services or Project-level services. To define permissions required to access both global and project-level services, enclose the permissions in two separate custom policies for refined authorization.
- Click OK.
- Modify the statement in the template.
- Effect: Set it to Allow or Deny.
- Action: Enter the actions listed in the API actions table of the EVS service, for example, evs:volumes:create.
NOTE:
The version of each custom policy is fixed at 1.1.
- (Optional) Enter a brief description for the policy.
- Click OK. If the policy list is displayed, the policy is created successfully. If a message indicating incorrect policy content is displayed, modify the policy.
- Attach the policy to a user group. Users in the group then inherit the permissions defined in this policy.
NOTE:
You can attach custom policies to a user group in the same way as you attach system-defined policies. For details, see Creating a User Group and Assigning Permissions.
