使用 AWS Panorama 管理设备 API

您可以使用 AWS Panorama 自动执行设备管理任务API。

查看设备

要获取带有设备的设备列表IDs，请使用ListDevicesAPI。

$ aws panorama list-devices
    "Devices": [
        {
            "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere",
            "Name": "my-appliance",
            "CreatedTime": 1652409973.613,
            "ProvisioningStatus": "SUCCEEDED",
            "LastUpdatedTime": 1652410973.052,
            "LeaseExpirationTime": 1652842940.0
        }
    ]
}

要获取有关设备的更多详细信息，请使用DescribeDeviceAPI。

$ aws panorama describe-device --device-id device-4tafxmplhtmzabv5lsacba4ere
{
    "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere",
    "Name": "my-appliance",
    "Arn": "arn:aws:panorama:us-west-2:123456789012:device/device-4tafxmplhtmzabv5lsacba4ere",
    "Type": "PANORAMA_APPLIANCE",
    "DeviceConnectionStatus": "ONLINE",
    "CreatedTime": 1648232043.421,
    "ProvisioningStatus": "SUCCEEDED",
    "LatestSoftware": "4.3.55",
    "CurrentSoftware": "4.3.45",
    "SerialNumber": "GFXMPL0013023708",
    "Tags": {},
    "CurrentNetworkingStatus": {
        "Ethernet0Status": {
            "IpAddress": "192.168.0.1/24",
            "ConnectionStatus": "CONNECTED",
            "HwAddress": "8C:XM:PL:60:C5:88"
        },
        "Ethernet1Status": {
            "IpAddress": "--",
            "ConnectionStatus": "NOT_CONNECTED",
            "HwAddress": "8C:XM:PL:60:C5:89"
        }
    },
    "LeaseExpirationTime": 1652746098.0
}

升级设备软件

如果 LatestSoftware 版本比 CurrentSoftware 版本新，您可以升级设备。CreateJobForDevicesAPI使用创建 over-the-air (OTA) 更新任务。

注意

任何超过 8.0.29 的更新都将意味着 Sagemaker Neo 模型节点无法运行。如果您当前使用的是模型节点，GPU则建议使用直接硬件访问来直接在上运行模型，或者选择不升级。更新 8.0. AWS 29 之后使用 Panorama有关更新后如何处理应用程序的更多信息，请参阅。

$ aws panorama create-job-for-devices --device-ids device-4tafxmplhtmzabv5lsacba4ere \
  --device-job-config '{"OTAJobConfig": {"ImageVersion": "4.3.55"}}' --job-type OTA
{
    "Jobs": [
        {
            "JobId": "device-4tafxmplhtmzabv5lsacba4ere-0",
            "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere"
        }
    ]
}

在脚本中，可以使用 Bash 字符串操作填充作业配置文件中的映像版本字段。

例 check-updates.sh

apply_update() {
    DEVICE_ID=$1
    NEW_VERSION=$2
    CONFIG='{"OTAJobConfig": {"ImageVersion": "NEW_VERSION"}}'
    CONFIG=${CONFIG/NEW_VERSION/$NEW_VERSION}
    aws panorama create-job-for-devices --device-ids ${DEVICE_ID} --device-job-config "${CONFIG}" --job-type OTA
}

设备将下载指定的软件版本并自行更新。使用观看更新进度DescribeDeviceJobAPI。

$ aws panorama describe-device-job --job-id device-4tafxmplhtmzabv5lsacba4ere-0
{
    "JobId": "device-4tafxmplhtmzabv5lsacba4ere-0",
    "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere",
    "DeviceArn": "arn:aws:panorama:us-west-2:559823168634:device/device-4tafxmplhtmzabv5lsacba4ere",
    "DeviceName": "my-appliance",
    "DeviceType": "PANORAMA_APPLIANCE",
    "ImageVersion": "4.3.55",
    "Status": "REBOOTING",
    "CreatedTime": 1652410232.465
}

要获取所有正在运行的作业的列表，请使用ListDevicesJobs。

$ aws panorama list-devices-jobs
{
    "DeviceJobs": [
        {
            "DeviceName": "my-appliance",
            "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere",
            "JobId": "device-4tafxmplhtmzabv5lsacba4ere-0",
            "CreatedTime": 1652410232.465
        }
    ]
}

有关检查和应用更新的示例脚本，请参阅本指南 GitHub 存储库中的 check-updates.sh。

重新启动设备

要重新启动设备，请使用CreateJobForDevicesAPI。

$ aws panorama create-job-for-devices --device-ids device-4tafxmplhtmzabv5lsacba4ere --job-type REBOOT
{
    "Jobs": [
        {
            "JobId": "device-4tafxmplhtmzabv5lsacba4ere-0",
            "DeviceId": "device-4tafxmplhtmzabv5lsacba4ere"
        }
    ]
}

在脚本中，您可以获取设备列表，并选择一个设备以交互方式重新启动。

例 reboot-device.sh – 用法

$ ./reboot-device.sh
Getting devices...
0: device-53amxmplyn3gmj72epzanacniy     my-se70-1
1: device-6talxmpl5mmik6qh5moba6jium     my-manh-24
Choose a device
1
Reboot device device-6talxmpl5mmik6qh5moba6jium? (y/n)y
{
    "Jobs": [
        {
            "DeviceId": "device-6talxmpl5mmik6qh5moba6jium",
            "JobId": "device-6talxmpl5mmik6qh5moba6jium-8"
        }
    ]
}
