This document describes several authorization methods of Serverless Cloud Framework and demonstrates actual operations by configuring sub-account permissions.
Prerequisites
Serverless Cloud Framework enables you to quickly deploy your project to Serverless Application Center (SAC). Before the deployment, please make sure that you have registered a Tencent Cloud account.
Authorization Method
Authorizing by scanning code
When you perform deployment by running scf deploy, you can scan the QR code for quick authorization and deployment. After you grant the authorization by scanning the code, temporary key information (which will expire in 60 minutes) will be generated and written to the .env file in the current directory.
TENCENT_APP_ID=xxxxxx # `AppId` of authorizing account
TENCENT_SECRET_ID=xxxxxx # `SecretId` of authorizing account
TENCENT_SECRET_KEY=xxxxxx # `SecretKey` of authorizing account
If your account is a Tencent Cloud sub-account, policy authorization needs to be first configured by using the root account. For more information about the configuration, see Sub-account Permission Configuration.
Authorizing with local key
To eliminate the need for repeated authorization due to information expiration in case of authorization by scanning the code, you can authorize with a key. Create an .env file in the root directory of the project to be deployed and configure the Tencent Cloud SecretId and SecretKey information:
# .env
TENCENT_SECRET_ID=xxxxxxxxxx # `SecretId` of your account
TENCENT_SECRET_KEY=xxxxxxxx # `SecretKey` of your account
To ensure the account security, we recommend you use a sub-account key for authorization. The sub-account can be used to deploy the project only after being granted the relevant permissions. For more information about the configuration, see Sub-account Permission Configuration.
Configuring with permanent key
You can run the scf credentials command to quickly set the persistent storage of the global key information. This command must be configured under the created SCF project. Make sure that you have created a project with serverless.yml by using scf init or manually.
Below are all the commands:
scf credentials Manage global user authorization information
set Store user authorization information
--secretId / -i (Required)`secretId` of the Tencent Cloud CAM account
--secretKey / -k (Required)`secretKey` of the Tencent Cloud CAM account
--profile / -n {name} Authorization name, which is `default` by default
--overwrite / -o Overwrite the key with an existing authorization name
remove Remove user authorization information
--profile / -n {name}(Required) Authorization name
list View user authorization information
Configure global authorization information:
# Configure authorization information through the default profile name
$ scf credentials set --secretId xxx --secretKey xxx
# Configure authorization information through the specified profile name
$ scf credentials set --secretId xxx --secretKey xxx --profile profileName1
# Update the authorization information in the specified profile name
Perform deployment by using the global authorization information:
# Deploy through the default profile
$ scf deploy
# Deploy through the specified profile
$ scf deploy --profile newP
# Ignore global variables and scan the QR code for deployment
$ scf deploy --login
Sub-account Permission Configuration
Directions
If you use a Tencent Cloud sub-account, it does not have the operation permissions by default; therefore, it needs to be authorized by the root account (or a sub-account with the authorization permission) in the following steps:
1. On the CAM User List page, select the target sub-account and click Authorize in the Action column.
2. Search for and select QcloudscfFullAccess in the pop-up window and click OK to grant the sub-account the permission to manipulate all Serverless Cloud Framework resources.
3. On the CAM User List page, select the target sub-account and click the username to go to the user details page.
4. Click Associate Policy. On the policy adding page, click the Select policies from the policy list tab, and then click Create Custom Policy.
Policy association page:
Policy creation page:
5. Choose Create by Policy Syntax > Blank Template and enter the following content. Make sure to replace the role parameter with the UIN of your root account:
{
"version":"2.0",
"statement":[
{
"action":[
"cam:PassRole"
],
"resource":[
"qcs::cam::uin/${Enter the UIN of your account}:roleName/scf_QcsRole"
],
"effect":"allow"
},
{
"resource":[
"*"
],
"action":[
"name/sts:AssumeRole"
],
"effect":"allow"
}
]
}
6. After completing the custom policy configuration, go back to the authorization page in step 4, search for the custom policy just created, click Next, and then click OK to grant the sub-account the operation permissions of scf_QcsRole. At this point, your sub-account should have a custom policy and a preset policy QcloudscfFullAccess and can use Serverless Cloud Framework normally.
Note
In addition to the permission to call the default scf_QcsRole role, you can also grant the sub-account the permission to call a custom role and control the sub-account permissions with refined permission policies in the custom role. For more information, see Configuring Role for Specified Operation.
