Deploying a web application with a few clicks

This topic describes how to deploy a web application with a few clicks via the veFaaS application center.

Background information

Application introduction

Based on the Node.js runtime, quickly deploy a web application accessible over the public network for users. After successful deployment, access can be made through the domain name provided by the API Gateway trigger.

Runtime

Node.js runtime

Associated cloud services

veFaaS: Uses the corresponding runtime template to build a web application.

API Gateway: Uses the gateway service to expose the public domain name of the web application.

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 pane, click App.

On the My app page, click Create app.

On the Create application page, select the volcano-webserver-node14 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. The volcano-webserver-node14 is used in this scenario.
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.

Validating results

After the application is successfully deployed, click the access address under API Gateway in the cloud resources list to view the "Hello Serverless!" message returned by the web application.
