Serverless App Engine:Deploy a PHP application by using an image in the SAE console

(Optional) Configure image synchronization in the Container Registry console

If the Alibaba Cloud image repository that you want to use does not reside in the same region as your application, you must use the image synchronization feature of Container Registry to synchronize the image repository to the region where the application resides before you deploy the application.

1. Log on to the Container Registry console.

2. In the top navigation bar, select a region.

3. On the Instances page, click Instance of Personal Edition to go to the Instance of Personal Edition page.

4. In the left-side navigation pane, choose Repository > Repositories. On the Repositories page, click the name of the repository that you want to manage.

5. In the left-side navigation pane, click Image Replication. On the Image Replication page, click Create.

6. In the Sync dialog box, configure the following parameters and click Confirm.

   

   • Tag: the version of the current image.

   • Target: Specify the region, namespace, repository name, and version number of the destination repository in sequence.

   After the image synchronization is completed, the image repository that you selected in the Container Registry console is synchronized to the specified destination repository. Then, you can select the image in the Deployment Configurations step when you deploy an application in the SAE console.

Deploy an application

1. Log on to the SAE console.

2. In the left-side navigation pane, click Applications. In the top navigation bar, select a region. Then, click Create Application.

3. In the Basic Information step, configure the parameters and click Next: Application Deployment Configurations.

   Parameter	Description
   Application Name	Enter a custom application name.
   VPC	Select a configuration method for the VPC. Valid values: Custom Configuration: If you select this option, you must manually specify the namespace, VPC, vSwitch, and security group for the application that you want to create. Automatic Configuration: If you select this option, SAE automatically specifies the namespace, VPC, vSwitch, and security group for the application.
   Namespace	This parameter is required if you set the VPC parameter to Custom Configuration. Select an existing namespace from the drop-down list. Namespaces and VPCs are in one-to-one mapping relationships. For information about how to modify a VPC, see Create and manage a VPC.
   vSwitch	This parameter is required if you set the VPC parameter to Custom Configuration. Click Select vSwitch. In the Select vSwitch dialog box, select the required vSwitches. You must specify at least one vSwitch. We recommend that you specify no more than three vSwitches. Each vSwitch must match at least one application instance.
   Security Group	This parameter is required if you set the VPC parameter to Custom Configuration. Select a security group from the drop-down list. If you have not created a security group in your VPC, click Create Security Group to create a security group as prompted. For more information, see Create a security group.
   Application Instances	Select the number of instances that you want to create.
   VCPU	Select a CPU specification for the instances that you want to create.
   Memory	Select a memory specification for the instances that you want to create.
   Application Description	Enter a description for the application.

4. In the Deployment Configurations step, configure the parameters.

   1. Configure the parameters that are used to deploy an application.

      Parameter	Description
      Technology Stack Programming Language	Select PHP.
      Technology Stack Version	This parameter is required if you set the Technology Stack Programming Language parameter to PHP. Select the language version of the PHP application. Important You must set the Technology Stack Version parameter to a valid value. An invalid value may cause an exception when the PHP application runs.
      Application Deployment Method	Select Image.
      Configure Image	Select the type of image that you want to use.

   2. Optional. Configure the advanced settings based on your business requirements.

      Advanced setting	References
      Modify php.ini Configuration File	Configure a configuration file for a PHP application
      Startup Command Settings	Configure a startup command
      Environment Variable Settings	Configure environment variables
      Service Registration and Discovery	Configure application access based on Kubernetes Service names Use the SAE built-in Nacos registry
      Hosts Binding Settings	Configure hosts binding
      Application Health Check	Configure application health checks
      Application Outbound/Inbound Internet Access	Bind an EIP to a NAT gateway Enable Internet access for SAE instances based on EIPs
      Application Lifecycle Management	Configure application lifecycle management
      Log Collection Service	Configure log collection to Simple Log Service Configure log collection to ApsaraMQ for Kafka
      Persistent Storage	Configure NAS storage
      Configuration Management	Inject configurations

5. Click Next: Confirm Specifications.

6. In the Specification Confirmation step, view the details of the application and the fee for the selected specifications. Then, click Confirm.

   The Creation Completed step appears. You can click Application Details to go to the Basic Information page of the application.

Verify the deployment result

After an application is deployed, you can use one of the following methods to verify the deployment result for the application.

• View the running status of application instances.

  1. Log on to the SAE console.

  2. In the left-side navigation pane, click Applications. On the Applications page, click the name of the application that you want to manage.

  3. On the Basic Information page, click the Instance Deployment Information tab to view the running status of the instances.

     If Running or Completed is displayed in the Status column, the application is deployed.

• Add an Internet-facing Server Load Balancer (SLB) instance to the application.

  After an application is deployed, you can configure an SLB instance to allow access to the application within a specified period of time for other applications.

  SLB instances are classified into the following types:

  • Internal-facing SLB instance: provides an access portal in the VPC where the application resides to ensure that the application can be accessed by other applications in the same VPC.

  • Internet-facing SLB instance: SAE can automatically purchase an Internet-facing SLB instance for an application, or you can use an Internet-facing SLB instance that you purchased in the SLB console. This helps ensure that the application can be accessed by other applications over the Internet.

  Note

  You can allow access to an application by using an Internet-facing SLB instance the same way you allow access to an application by using an internal-facing SLB instance. For more information, see Bind an SLB instance to an application. After an SLB instance is bound to an application, you can enter a URL that consists of the IP address, port, and access path of the SLB instance in the address bar of your browser to access the application. Example: 192.168.XX.XX:80/image.

View application metrics

After an application is deployed, you can view the key performance metrics of the application in the Application Monitoring module.

1. Log on to the SAE console.

2. In the left-side navigation pane, click Applications. In the top navigation bar, select a region. Then, click the name of the application that you want to manage.

3. In the left-side navigation pane, view application monitoring data based on your business requirements.

   • Application Overview: Choose Application Monitoring > Application Overview. The Application Overview page displays the key performance metrics of the application, such as the total number of requests and the average response time.

   • Application Details: Choose Application Monitoring > Application Details. The Application Details page displays more comprehensive application monitoring data, such as the data for JVM monitoring and exception analysis.

   • API Operation Calls: Choose Application Monitoring > API Operation Calls. The API Operation Calls page displays the monitoring data by API operation, such as the call topology, upstream and downstream links.

   • Advanced Monitoring: Choose Application Monitoring > Advanced Monitoring. The Advanced Monitoring page displays higher-performance monitoring and management data, such as global application topology, data of SQL exception analysis, and local call stack.
