Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8) 
This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Where:

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 handling.

leverages its existing relationships with the Yocto Project to enhance development, bug fixes and other activities in the Yocto Project kernel to drive 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, , etc., as well as some services from OpenStack such as the OpenStack Horizon Web interface, Keystone and Barbican.

StarlingX

Hardware and software infrastructure management.

  • Manages installation, maintenance and fault monitoring of dedicated bare metal servers running the 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.
Kubernetes
  • Kubernetes Container Orchestration Engine
  • Native Docker Runtime
  • Calico Container Networking
  • Accelerated Container Networking with multus and
  • Persistent Volume Claims backed by Ceph
  • Local Docker Registry
  • Helm / Tiller – Kubernetes Package Manager, and
  • FluxCD
OpenStack
  • Keystone - Identity management
  • Nova - compute management
  • Neutron - network management
  • Glance - image management
