How to create an NGINX application by using OSS and ROS - Object Storage Service

You can compile stack templates to describe cloud computing resources, such as Elastic Compute Service (ECS) and ApsaraDB RDS instances, and the dependencies between resources in the stack templates by using Resource Orchestration Service (ROS). The orchestration engine of ROS automatically creates and configures all resources based on templates to implement automated deployment and O&M. This topic describes how to create an NGINX application by using Object Storage Service (OSS) and ROS.

Prerequisites

An OSS bucket whose access control list (ACL) is private is created. For more information about how to create a bucket, see Create buckets.
The NGINX installation package is downloaded.

Step 1: Upload the NGINX installation package to the bucket

Log on to the OSS console.
In the left-side navigation pane, click Buckets. On the Buckets page, find and click the desired bucket.
In the left-side navigation tree, choose Object Management > Objects.
Upload the downloaded NGINX installation package.
Set the access control list (ACL) of the NGINX installation package to public-read and keep the default settings for other parameters. For more information about how to upload an object, see Upload objects.
Obtain the object URL.
Click View Details on the right side of the NGINX installation package, and then click Copy Object URL.

Step 2: Create a stack by using ROS

Select the template that you want to use to create a stack.

Log on to the ROS console.
In the left-side navigation pane, click Stacks.
In the top navigation bar, select China (Hangzhou) from the region drop-down list.
On the Stacks page, click Create Stack and select Use ROS from the drop-down list.

In the Select Template step, set Specify Template to Select an Existing Template and Template Import Method to Enter Template Content. In the Template Content section, click ROS and JSON, enter the following template content in the code editor, and then click Next.

Configure the parameters.

In the Configure Parameters step, specify the Stack Name parameter.

In the Configure Template Parameters section, configure the following parameters.

Section	Parameter	Description
Infrastructure Configuration	Existing VPC Instance ID	Select a virtual private cloud (VPC) from the drop-down list.
	VSwitch ID	Select a vSwitch from the drop-down list.
	Security Group ID	Select a security group from the drop-down list.
ECS Configuration	VSwitch Availability Zone	Select a vSwitch zone based on your business requirements, such as Zone G.
	Image	Enter centos_7.
	Instance Type	Select an instance type based on your business requirements.
	System Disk Type	Select cloud_ssd.
	Instance Password	Enter the custom logon password of the ECS instance.
	Nginx Download Url	Enter the object URL of the NGINX installation package that you obtained in Step 1.

In the Configure Stack Settings section, retain the default settings.
Click Create.

Visit the homepage of NGINX in a browser.
1. Click the stack that you created.
2. Click Outputs and then click the URL of NGINX.
  After you click the URL of NGINX, you are redirected to the homepage of NGINX.
  If you cannot access the homepage of NGINX, add the default port HTTP(80) to the current security group. For more information, see Add a security group rule.
