Cumulocity IoT Edge Appliance VM

Upgrade of Rocky Linux operating system version to 8.10

This release upgrades the Rocky Linux operating system from version 8.9 to 8.10. For details on updating Edge from version 10.18.0.0 to 10.18.0.1, refer to Updating Edge. Due to the inclusion of the new Rocky Linux version in the 10.18.0.1 update archive, the archive size has significantly increased, resulting in a longer update process compared to previous versions. For instructions on upgrading Edge from version 10.17, see Migrating Edge 10.17 to 10.18.

Fixes

Known issues

Cumulocity IoT Edge on Kubernetes

Cumulocity IoT Edge on Kubernetes has reached General Availability (GA) and is now ready for deployment in production environments.

Offline installation

Edge installation on Kubernetes now offers support for installation in an offline or air-gapped environment. This ensures that the required software, Helm charts and Docker images, are available in the disconnected environment through an Open Container Initiative (OCI) compliant private registry.

For more information, refer to Installing the Edge operator (offline).

Metrics monitoring port

The Edge operator’s Prometheus-compatible metrics port has been changed from 8443 to 3443 due to a conflict with another core component.

For detailed instructions, refer to Monitoring.

Cumulocity IoT Edge Appliance VM

Rocky Linux 8

As CentOS 7 will reach its end-of-life on June 30th, 2024, we are transitioning our support to an alternative Operating System for Edge Appliance users. Starting with this release, the Edge Appliance VM is equipped with Rocky Linux 8. Since the Operating System is changed, the upgrade from earlier versions of Edge entails a side-by-side installation accompanied by data migration. For information on upgrading Edge version 10.18, see Migrating Edge 10.17 to 10.18.

Cumulocity IoT Edge on Kubernetes

Cumulocity IoT Edge on Kubernetes has reached General Availability (GA) and is now ready for deployment in production environments.

Remote software management

Using the Cumulocity IoT software management feature, users can now remotely manage applications, microservices, and extensions installed on Edge.

For detailed instructions, refer to Managing software remotely.

Metrics monitoring

Edge deployments on Kubernetes can be monitored utilizing Prometheus, an open-source tool designed for monitoring application states. The Edge operator provides a Prometheus-compatible metrics endpoint, allowing you to track a diverse range of resource usage and availability metrics.

For detailed instructions, refer to Monitoring.

Offline installation

Edge installation on Kubernetes now offers support for installation in an air-gapped environment. This ensures that all dependencies are accessible locally, eliminating the need for internet access during the installation process.

For more information, refer to Installing the Edge operator (offline).

Important announcements

Deprecation of Cumulocity Linux Agent in Cumulocity IoT Edge

With the release of Cumulocity IoT Edge version 10.18, we are announcing the deprecation of the Cumulocity Linux Agent included in the Cumulocity IoT Edge offering. Version 10.18 will mark the final release to feature the Cumulocity Linux Agent.

Previously, Cumulocity IoT Edge utilized the Cumulocity Linux Agent to support protocols such as Modbus and CANopen, as well as to collect and publish resource consumption metrics. Moving forward, Edge will internally manage the collection and publication of resource consumption metrics.

If your use case involves Modbus-TCP or Modbus-RTU, we recommend migrating to the thin-edge.io connectors for Cumulocity IoT. For users of CANopen, we suggest considering migration to one of our partner-supported solutions or deploying Cumulocity Linux Agent as an additional component.

We are fully committed to assisting and guiding you through this transition. Should you have any questions or require further assistance, reach out to our support team.

We sincerely appreciate your understanding and cooperation as we strive to improve and expand our product offerings.
