Deploying AI painting Stable Diffusion applications with a few clicks

This topic describes how to deploy an AI painting Stable Diffusion application with a few clicks by using the Application Center of veFaaS.

tip

[Beta - apply for trial] This application requires GPU computing power support. Serverless GPU is currently in beta. Contact your account manager to apply for a trial.

Background information

Application introduction

This application provides the Serverless deployment capability of the stable-diffusion-webui project. After deployment, you can use the Stable Diffusion WebUI through the domain name provided by API Gateway Trigger, including text-to-image, image-to-image, and advanced features such as Lora and ControlNet.

Runtime

Native runtime

Associated cloud services

veFaaS: Performs GPU inference computation on AIGC.

APIG: Sends requests for AIGC image generation.

Prerequisites

All the cloud services associated with the application have been activated.

The VeFaaSFullAccess, APIGFullAccess, and STSAssumeRoleAccess policies have been attached to Identity and Access Management (IAM) users. If one of the preceding policies is not attached, contact the root user or the administrator for authorization. For specific operations, refer to Creating user and authorize.

An APIG instance has been created in APIG. For detailed operations, see Creating instances.

If you use veFaaS for the first time, make sure that the cross-service authorization is complete. If the authorization is not complete, the cross-service authorization page will appear, which provides guidance on authorization.

Procedure

In the top navigation bar, select the target region.

In the left navigation bar, click App.

On the My app page, click Create app.

On the Create app page, find the volcano-stable-diffusion template and click Create.

On the Create App page, specify the following information as required.

Basic information

Parameter	Description
Selected template	Displays the selected template. In this scenario, the template is volcano-stable-diffusion.
Name	Specify a custom name for the application.
Description	Enter the description of the application. This parameter can be left empty.
IAM role	The Application Center provides the system default role ServerlessApplicationRole, which is granted permissions on some cloud resources that the Application Center needs to access. If your user roles do not contain this role, this role will be automatically added. If your user roles contain this role, the system will automatically detect whether all the policies required for the application are attached to this role. If a required policy is not attached, the console will display the name of the policy. You can click Add policy to add the policy. warning Make sure that the IAMReadOnlyAccess policy is attached to IAM users. Otherwise, they will not be authorized to obtain information about the ServerlessApplicationRole role. If IAM users need to attach policies to the ServerlessApplicationRole role, make sure that the IAMFullAccess policy is attached to the IAM users.
Associated cloud services	Displays the names, activation status, and activation purposes of all the cloud services that the current application needs to use.

Advanced settings

Parameter	Description
Region	The region where the application and its associated cloud resources are located.
Function name	Specify a custom name for the function.
API Gateway instance	Select the target API Gateway instance. The resources related to the API Gateway trigger, including services, Upstream, and routes, will be automatically created for this API Gateway instance.

Click Confirm to create and deploy the application.

You will be automatically redirected to the application details page, which displays the application deployment logs in real time.

Result validation

After the application is deployed, click the access address under API Gateway in the cloud resources list to open the Stable Diffusion WebUI page.

In the text box on the txt2img tab, enter the prompt and click Generate to generate an image that matches the prompt.
