Host deployment and management

Prerequisites

An edge device has been activated. For more information, see Activate an edge device.

What is a deployment

Deployment is the process of synchronizing resources or configuration information from the cloud to an edge device. The Deploy button in the console lets you perform a one-click synchronization of resources and configurations between the cloud and the edge. After you deploy, you can view the deployment progress and review deployment logs.

In IoT Edge, the following resources take effect only after they are deployed:

• In Terminal Device Management, driver and device configurations for general-purpose devices.

• In Application Management, deployments and configuration changes for process-based applications.

Deploy a host

1. Log on to the IoT Edge console.

2. From the drop-down list in the navigation pane on the left, select your instance.

3. In the navigation pane on the left, choose Node Management > Host Management.

4. In the Actions column for the target host, click Deploy Host.

Manage a host

On the Host Management and Host Details pages, you can use the buttons to manage the host.

• The following table describes the buttons on the Host Management page:

  Operation	Description
  Host Details	View and manage the basic information, monitoring information, and application instances assigned to the host. For more information, see the "Function buttons on the Host Details page" table below.
  Deploy Host	Perform a one-click deployment of cloud resources to the edge device.
  O&M Alerting	Click O&M Alerting. The system navigates to the O&M Alerting page of the host to view all alert information. For more information, see O&M Alerting.
  System Events	Click System Events. The system navigates to the System Events page of the host to view all system events. For more information, see System Events.
  Activate Application	Some models of edge devices support pre-installed applications. See the user manual that came with your purchased edge device to confirm the supported pre-installed applications. Click Activate Application. In the dialog box that appears, select the target application and click Activate to the right of the application name. The activation process varies by application. Follow the system prompts to complete the configuration.
  Terminal Device Management	Manage the terminal devices associated with the host. For more information, see Terminal Device Management.
  Algorithm Task Management	Manage algorithm applications, algorithm services, and algorithm tasks for the host. For more information, see Algorithm Task Management.
  Disable Alerting	Disable all alerts for software and hardware resources associated with the host. Use this feature with caution.
  Request After-sales Support	On the Request After-sales Support panel, upload a photo of the host's nameplate and describe the hardware issue to request after-sales service and support for the edge device.
  Remote Access Host	Click Remote Access Host, Share Remote Terminal, or More Remote Services to remotely control the edge device. For details and instructions, see Remote O&M Management.
  Share Remote Terminal
  More Remote Services
  Remove	Delete all cloud configurations for the edge device. Use this feature with caution. When the host is in the Removing state, the Force Remove button appears. Use it to forcibly remove the host if it cannot be removed normally. Warning The Remove or Force Remove operation only deletes the cloud configurations of your edge device. To delete local configurations, log on to the edge device management console and restore the edge device to its factory settings. For more information, see System Administration.
  Force Remove
  Replace Host	This button is displayed when the host is in the Offline state. Seamlessly migrate the configuration of an old edge device to a new one. Important Host replacement is only supported between edge devices of the same model. Follow the system prompts and scan the QR code on the new edge device to complete the host replacement. After scanning the QR code on the new edge device, use your Alibaba Cloud account to log on to the activation page. (Optional) If your Alibaba Cloud account has not been granted product permissions or cloud resource access permissions, click the authorization button as prompted by the system to grant them. On the Host Activation Process page, click Replace Host, select the host to be replaced, and then click Continue to start the replacement. Warning The host replacement process takes 10 to 15 minutes. Once started, the process cannot be canceled, and the host being replaced cannot be used. Confirm whether you need to back up data before starting the replacement.
  Shutdown	Remotely shut down the power of the edge device, take it offline from the cloud, and stop associated services. When the device is powered on again using its power switch or power plug, the associated services automatically restart.
  Restart	Restart the host corresponding to the edge device without affecting its configuration. Warning The restart process interrupts the services associated with the host. After the restart is complete, the associated services automatically resume. Avoid restarting during peak business hours.

• The following sections describe the tabs on the Host Details page:

  • Basic Information tab

    Operation	Description
    Host Name	The host name you set when activating the edge device. Click Modify to change the host name. The name can contain Chinese characters, uppercase and lowercase English letters, and numbers. The following special characters are supported: _ () -. The name must be 1 to 60 characters in length. A Chinese character counts as two characters.
    Log Upload to Cloud	IoT Edge provides a log service. Turn on the switch to enable the log service. Important Enabling the log service generates additional traffic and consumes storage space in your Alibaba Cloud Simple Log Service. For details and billing information about Alibaba Cloud Simple Log Service, see the Simple Log Service documentation.
    Version	The base version of the current edge device. Click Version Details to view information about this version and available upgrades. For information about version upgrades, see Version Upgrade.
    Deployment Address	Displays the deployment address of the current edge device. Click Modify to automatically detect the deployment address or manually change it.
    Monitoring	IoT Edge provides a host monitoring feature for edge devices. After you turn on the switch, you can view the current host monitoring information on the Host Monitoring tab.
    Node Autonomy	IoT Edge provides node autonomy features for edge devices that have container management capabilities and have the cluster management service enabled. Turn on the Node Autonomy switch. This means that if this edge device goes offline, another edge device in a primary/secondary relationship with it does not need to be started to run the applications or algorithms on this edge device. Note For information about edge devices with container management capabilities, contact your business representative for the edge device. If you do not have an edge device with container management capabilities, you can contact us and leave a message for consultation.
    High-performance Mode	IoT Edge provides a CPU high-performance mode. Turn on the CPU high-performance mode to enhance the computing power of the edge device. Important Turning on high-performance mode increases the heat generation and power consumption of the edge device.
    Local Password Management	Click Modify Local Password to change the logon password for the edge device. There are two Modification Types: Host root account logon password This is the logon password for the SSH terminal of the edge device. You can log on to the SSH terminal of the edge device directly or remotely. For information about remote logon, see Remote Service Access. Follow the system prompts, enter your current password, new password, and confirm the new password, then click OK. Edge device management console logon password Follow the system prompts, enter your current password, new password, and confirm the new password, then click OK. For information about the console, see Introduction to the edge device management console.

  • Host Monitoring tab

    This tab displays monitoring information, such as the host status and resource usage of the current edge device.

  • Application Instances tab

    On this tab, you can assign containerized or process-based applications to the current edge device. For more information about application management, see Application Management.
