StarlingX includes a rich functionality set from open source projects.
The high-level functional diagram of StarlingX is shown in the diagram below:
- Hardened Linux
Linux 5.10 Yocto-based kernel ( https://www.yoctoproject.org/ )
The Yocto Project Kernel:
tracks stable kernel updates very closely; staying very current with the stable kernel,
provides a reliable implementation of the pre-empt-rt patchset (see: https://rt.wiki.kernel.org/index.php/Main_Page), and
provides predictable and searchable CVE handling.
StarlingX leverages its existing relationships with the Yocto Project to enhance development, bug fixes and other activities in the Yocto Project kernel to drive StarlingX quality and feature content.
Debian Bullseye (11.3)
Debian is a well-established Linux Distribution supported by a large and mature open-source community.
OSTree ( https://ostree.readthedocs.io/en/stable/manual/introduction/ )
OSTree provides for robust and efficient versioning, packaging and upgrading of Linux-based systems.
An updated Installer to seamlessly adapt to Debian and OSTree
Updated software patching and upgrades for Debian and OSTree.
- Variety of open-source software supporting StarlingX and/or Kubernetes
This includes packages such as Apache, Ceph, PostgreSql, Etcd, IPMI, etc., as well as some services from OpenStack such as the OpenStack Horizon Web interface, Keystone and Barbican.
Hardware and software infrastructure management.
Manages installation, maintenance and fault monitoring of dedicated bare metal servers running the StarlingX solution.
Manages the configuration of hardware and software services running on the host servers.
Provides the cluster management for services running on the HA master/control nodes cluster, as well critical software monitoring and recovery of services running on all nodes within the cluster.
Monitoring and reporting of faults and logs of both hardware and software services.
Support for managing software updates to all layers of software in the solution; this includes kernel, operating system, open-source packages, StarlingX and Kubernetes.
