在 Raspberry Pi 4 上运行的 Azure Edge 中的 Node-RED 模块提示“退避”错误

Question

我正在尝试让noderededgemodule 在 Raspberry Pi 4 上的 Azure Edge 上运行。我还有一些其他模块运行良好，但这个会提示“退避”错误。我不确定这意味着什么，以及如何解决它。我目前正在使用 AMD64 模块，但尝试过 ARM32

pi@raspberrypi:~ $ sudo iotedge check

Configuration checks
--------------------
√ config.yaml is well-formed - OK
√ config.yaml has well-formed connection string - OK
√ container engine is installed and functional - OK
√ config.yaml has correct hostname - OK
√ config.yaml has correct URIs for daemon mgmt endpoint - OK
√ latest security daemon - OK
√ host time is close to real time - OK
× container time is close to host time - Error
    Detected time drift between host and container
‼ DNS server - Warning
    Container engine is not configured with DNS server setting, which may impact connectivity to IoT Hub.
    Please see https://aka.ms/iotedge-prod-checklist-dns for best practices.
    You can ignore this warning if you are setting DNS server per module in the Edge deployment.
‼ production readiness: certificates - Warning
    The Edge device is using self-signed automatically-generated development certificates.
    They will expire in 77 days (at 2020-07-27 15:36:55 UTC) causing module-to-module and downstream device communication to fail on an active deployment.
    After the certs have expired, restarting the IoT Edge daemon will trigger it to generate new development certs.
    Please consider using production certificates instead. See https://aka.ms/iotedge-prod-checklist-certs for best practices.
√ production readiness: container engine - OK
‼ production readiness: logs policy - Warning
    Container engine is not configured to rotate module logs which may cause it run out of disk space.
    Please see https://aka.ms/iotedge-prod-checklist-logs for best practices.
    You can ignore this warning if you are setting log policy per module in the Edge deployment.
‼ production readiness: Edge Agent's storage directory is persisted on the host filesystem - Warning
    The edgeAgent module is not configured to persist its /tmp/edgeAgent directory on the host filesystem.
    Data might be lost if the module is deleted or updated.
    Please see https://aka.ms/iotedge-storage-host for best practices.
‼ production readiness: Edge Hub's storage directory is persisted on the host filesystem - Warning
    The edgeHub module is not configured to persist its /tmp/edgeHub directory on the host filesystem.
    Data might be lost if the module is deleted or updated.
    Please see https://aka.ms/iotedge-storage-host for best practices.

Connectivity checks
-------------------
√ host can connect to and perform TLS handshake with IoT Hub AMQP port - OK
√ host can connect to and perform TLS handshake with IoT Hub HTTPS / WebSockets port - OK
√ host can connect to and perform TLS handshake with IoT Hub MQTT port - OK
√ container on the default network can connect to IoT Hub AMQP port - OK
√ container on the default network can connect to IoT Hub HTTPS / WebSockets port - OK
√ container on the default network can connect to IoT Hub MQTT port - OK
√ container on the IoT Edge module network can connect to IoT Hub AMQP port - OK
√ container on the IoT Edge module network can connect to IoT Hub HTTPS / WebSockets port - OK
√ container on the IoT Edge module network can connect to IoT Hub MQTT port - OK

Answer 1

exec format error 是因为您试图在 Raspberry Pi 的 ARM 处理器上运行 x86_64 (AMD64) 编译的二进制文件。

这行不通，您只能在 ARM CPU 上运行 ARM 二进制文件。
