New features in this version¶
The list below provides a detailed list of new features and links to the associated user guides (if applicable).
StarlingX release 7.0 inherits the 5.10 kernel version from the Yocto project introduced in StarlingX release 6.0, i.e. the Debian 5.10 kernel is replaced with the Yocto project 5.10.x kernel (linux-yocto).
StarlingX release 7.0 is a Technology Preview Release of Debian StarlingX for evaluation purposes.
StarlingX release 7.0 release runs Debian Bullseye (11.3). It is limited in scope to the AIO-SX configuration, Duplex, and standard configurations are not available.. It is also limited in scope to Kubernetes apps and does not yet support running OpenStack on Debian.
Istio Service Mesh Application¶
The Istio Service Mesh application is integrated into StarlingX as a system application.
Istio provides traffic management, observability as well as security as a Kubernetes service mesh. For more information, see https://istio.io/.
StarlingX includes istio-operator container to manage the life cycle management of the Istio components.
Pod Security Admission Controller¶
The Beta release of Pod Security Admission (PSA) controller is available in StarlingX release 7.0 as a Technology Preview feature. It will replace Pod Security Policies in a future release.
PSA controller acts on creation and modification of the pod and determines if it should be admitted based on the requested security context and the policies defined. It provides a more usable k8s-native solution to enforce Pod Security Standards.
Platform Application Components Revision¶
The following applications have been updated to a new version in StarlingX Release 7.0.
The upgrade of cert-manager from 0.15.0 to 1.7.1 deprecated support for cert manager API versions cert-manager.io/v1alpha2 and cert-manager.io/v1alpha3. When creating cert-manager CRDs (certificates, issuers, etc) with StarlingX, Release 7.0, use API version of cert-manager.io/v1.
Cert manager resources that are already deployed on the system will be automatically converted to API version of cert-manager.io/v1. Anything created using automation or previous StarlingX releases should be converted with the cert-manager kubectl plugin using the instructions documented in https://cert-manager.io/docs/installation/upgrading/upgrading-0.16-1.0/#converting-resources before being deployed to the new release.
In StarlingX Release 7.0 the Metrics Server will NOT be automatically updated. To update the Metrics Server, see Install Metrics Server
StarlingX Release 7.0 supports helm-overrides of oidc-auth-apps application.
The recommended and legacy example Helm overrides of
oidc-auth-apps are supported for upgrades, as described in StarlingX
documentation User Authentication Using Windows Active Directory.
Bond CNI plugin¶
The Bond CNI plugin v1.0.1 is now supported in StarlingX Release 7.0.
The Bond CNI plugin provides a method for aggregating multiple network interfaces into a single logical “bonded” interface.
To add a bonded interface to a container, a network attachment definition of
bond must be created and added as a network annotation in the pod
specification. The bonded interfaces can either be taken from the host or
container based on the value of the
linksInContainer parameter in the
network attachment definition. It provides transparent link aggregation for
containerized applications via K8s configuration for improved redundancy and
PTP GNSS and Time SyncE Support for 5G Solutions¶
Intel’s E810 Westport Channel and Logan Beach NICs support a built-in GNSS
module and the ability to distribute clock via Synchronous Ethernet (SyncE).
This feature allows a PPS signal to be taken in via the GNSS module and
redistributed to additional NICs on the same host or on different hosts.
This behavior is configured on StarlingX using the
clock instance type in
the PTP configuration.
These parameters are used to enable the UFL/SMA ports, recovered clock syncE etc. Refer to the user’s guide for the Westport Channel or Logan Beach NIC for additional details on how to operate these cards.
PTP Clock TAI Support¶
A special ptp4l instance level parameter is provided to allow a PTP node to set the currentUtcOffsetValid flag in its announce messages and to correctly set the CLOCK_TAI on the system.
PTP Multiple NIC Boundary Clock Configuration StarlingX 7.0 provides support for PTP multiple NIC Boundary Clock configuration. Multiple instances of ptp4l, phc2sys and ts2phc can now be configured on each host to support a variety of configurations including Telecom Boundary clock (T-BC), Telecom Grand Primary clock (T-GM) and Ordinary clock (OC).
Enhanced Parallel Operations for Distributed Cloud¶
The following operations can now be performed on a larger number of subclouds in parallel. The supported maximum parallel number ranges from 100 to 500 depending on the type of operation.
Subcloud Deployment (bootstrap and deploy)
Subcloud Manage and Sync
Subcloud Application Deployment/Update
Firmware Update Orchestration
Kubernetes Upgrade Orchestration
Kubernetes Root CA Orchestration
--force option has been added to the dcmanager upgrade-strategy create
command. This option upgrades both online and offline subclouds for a single
subcloud or a group of subclouds.
Subcloud Local Installation Enhancements¶
Error preventive mechanisms have been implemented for subcloud local installation.
Pre-check to avoid overwriting installed systems
Unified ISO image for multiple systems and disk configurations
Prestage execution optimization
Effective handling of resized docker and docker-distribution filesystems over subcloud upgrade
Distributed Cloud Horizon Orchestration Updates¶
You can use the Horizon Web interface to upgrade Kubernetes across the Distributed Cloud system by applying the Kubernetes upgrade strategy for Distributed Cloud Orchestration.
You can use Horizon to update the device/firmware image across the Distributed Cloud system by applying the firmware update strategy for Distributed Cloud Update Orchestration.
You can upgrade the platform software across the Distributed Cloud system by applying the upgrade strategy for Distributed Cloud Upgrade Orchestration.

Security Audit Logging for Platform Commands¶
StarlingX logs all StarlingX REST API operator commands, except commands that use
only GET requests. StarlingX also logs all SNMP commands, including
Security Audit Logging for K8s API¶
Kubernetes API Logging can be enabled and configured in StarlingX, and can be fully configured and enabled at bootstrap time. Post-bootstrap, Kubernetes API logging can only be enabled or disabled. Kubernetes auditing provides a security-relevant, chronological set of records documenting the sequence of actions in a cluster.
Playbook for managing local LDAP Admin User¶
The purpose of this playbook is to simplify and automate the management of
composite Local LDAP accounts across multiple DC systems or standalone
systems. A composite Local LDAP account is defined as a Local LDAP account
that also has a unique keystone account with admin role credentials and access
to a K8S serviceAccount with
cluster-admin role credentials.
Kubernetes Custom Configuration¶
Kubernetes configuration can be customized during deployment by specifying
bootstrap overrides in the
localhost.yml file during the Ansible bootstrap
process. Additionally, you can also override the extraVolumes section in the
apiserver to add new configuration files that may be needed by the server.
Configuring Host CPU MHz Parameters¶
Some hosts support setting a maximum frequency for their CPU cores (application cores and platform cores). You may need to configure a maximum scaled frequency to avoid variability due to power and thermal issues when configured for maximum performance. For these hosts, the parameters control the maximum frequency of their CPU cores.
Enable support for power saving modes available on Intel processors to facilitate a balance between latency and power consumption.
StarlingX permits the CPU “p-states” and “c-states” control via the BIOS
Introduce a new starlingx-realtime tuned profile, specifically configured for the low latency profile to align with Intel recommendations for maximum performance while enabling support for higher c-states.
vRAN Intel Tool Enablement¶
The following open-source vRAN tools are delivered in the following container
OPAE Tools (Open Programmable Acceleration Engine,
ACPICA Tools (
PCM Tools (https://github.com/opcm/pcm, pcm, pcm-core, etc.)
See: vRAN Tools
Coredump Configuration Support¶
You can change the default core dump configuration used to create core files. These are images of the system’s working memory used to debug crashes or abnormal exits.
FluxCD replaces Airship Armada¶
StarlingX application management provides a wrapper around FluxCD and Kubernetes Helm (see https://github.com/helm/helm) for managing containerized applications. FluxCD is a tool for managing multiple Helm charts with dependencies by centralizing all configurations in a single FluxCD YAML definition and providing life-cycle hooks for all Helm releases.
See: StarlingX Application Package Manager. See: FluxCD Limitation note applicable to StarlingX Release 7.0.
Kubernetes has now been upgraded to k8s 1.23.1 and is the default version for StarlingX Release 7.0.
NetApp Trident Version Upgrade¶
StarlingX 6.0 contains the installer for Trident 22.01
If you are using NetApp Trident in StarlingX 6.0 and have upgraded from the StarlingX previous version, ensure that your NetApp backend version is compatible with Trident 22.01.
You need to upgrade the NetApp Trident driver to 22.01 before upgrading Kubernetes to 1.22.
