Install Func¶

It is recommended to enable Guance integration - extension - DataFlux Func (Automata): All prerequisites are automatically installed, please continue with the script installation.

If you deploy Func yourself, refer to Self-deployed Func

Installation Script¶

5. In the 【Cloud Account Management】 list, you can see the added cloud account. Click the corresponding cloud account to enter the details page.
6. On the cloud account details page, click the 【Integration】 button. In the Not Installed list, find AWS DynamoDB DAX, click the 【Install】 button, and follow the prompts to install.

Manual Script for Enabling¶

1. Log in to the Func console, click 【Script Market】, go to the official script market, and search for guance_aws_dynamodb_dax.

2. After clicking 【Install】, input the corresponding parameters: AWS AK ID, AK Secret, and account name.
