![]() ![]() You can troubleshoot the upgrade process at any time. On the device, start the IoT Edge using sudo iotedge config apply. In IoT Hub, update the module deployment to reference the newest system modules. If you're importing an old configuration using iotedge config import, then modify the image of the generated /etc/aziot/config.toml file to use the 1.4 image for edgeAgent.įor more information, see Configure IoT Edge device settings. On the device, upgrade your container engine, either Docker or Moby. On the device, stop IoT Edge using the command sudo systemctl stop iotedge and uninstall. To update between major or minor product releases: Before a release, we test the security subsystem and the runtime container version combination. When you upgrade between major or minor releases, for example from 1.1 to 1.4, update both the security subsystem and the runtime containers. You can upgrade the security subsystem or the runtime containers before or after the other. When you upgrade between patch releases, for example 1.4.1 to 1.4.2, the update order isn't important. Use the sections of this article to update both the security subsystem and runtime containers on a device. Depending on how you structure your deployment, the runtime can be updated from either the device or remotely. IoT Edge runtime - The IoT Edge runtime is made up of the IoT Edge hub ( edgeHub) and IoT Edge agent ( edgeAgent) modules. The security subsystem can only be updated from the device itself. It runs on the device, handles security-based tasks, and starts the modules when the device starts. Security subsystem - Although the architecture of the security subsystem changed between version 1.1 and 1.2, its responsibilities remained the same. Two logical components of an IoT Edge device need to be updated if you want to move to a newer version. This article provides information about how to update your IoT Edge devices when a new version is available. If you are on an earlier release, see Update IoT Edge.Īs the IoT Edge service releases new versions, update your IoT Edge devices for the latest features and security improvements. ![]()
