Release Notes for SCS Release 0

(Release Date: 2021-07-15)

Scope

The main focus of R0 is to demonstrate the viability of our approach to a much broader audience by providing a well-documented testbed. This will allow anyone interested to study the system in real-life, test, contribute, compare, ... it.

Also we learn performing the release process.

Features

Fully automated virtual (testbed setup) with ansible (terraform bootstrap to create storage, networking and VM resources for bootstrapping via cloud-init injected scripts that call ansible).)

The infrastructure, management and openstack services are all deployed in containers.

Included tools for Operations: ARA, Netbox, Cockpit, Netdata, Skydive (opt-in), Patchman, phpMyAdmin, Elasticsearch (b/f license change), Kibana, Grafana, influxdb

Validation: Rally, Refstack

Infrastructure: Linux, KVM, ceph (pacific), OpenVSwitch, OVN, MariaDB, RabbitMQ, Redis, Etcd, HAproxy, Keepalived, Memcached, Keycloak

IaaS (OpenStack - Wallaby): keystone, nova, glance, cinder, neutron, octavia, horizon

Optional OpenStack services: designate, heat, gnocchi, ceilometer, aodh, panko, senlin, barbican, manila, magnum

See testbed SBOM for a complete list. The exact versions of the contained components can be retrieved from the release repo of OSISM.

Technical Previews

While already in productive use (on bare metal) by two providers, the bare metal setup currently has a few more manual steps than we would like. This will improve with the next releases.

We have worked hard on supporting identity federation (OIDC and SAML) during the last few months. We have also spent significant effort on getting the k8s stack with k8s cluster API into a good shape. However, we have determined that we do not yet consider those two key pieces as production-ready. The goal is to change that for R1 (see below).

For now, you can use the software to see where SCS is going and test our technical preview code. We really appreciate feedback we get on these pieces as well. However keep in mind that we do not guarantee to ship technical previews from a Release as production-ready software in one of the next releases. We certainly hope to do so.

To test how our k8s aaS platform will look like, have a look at https://github.com/SovereignCloudStack/k8s-cluster-api-provider You can follow the documentation to set up the k8s cluster API on an SCS cloud (or other well configured OpenStack clouds that support octavia).

The openstack-health-monitor is used by us to monitor that the API works and successfully creates working resources in finite time. We plan to integrate it with a dashboard and an alarming mechanism in the next releases.

Release tagging

See Release Numbering scheme. The containers have version number v1.0.0 for R0.

Updates

Updating the software can conveniently be done from the manager node by running the ansible playbooks again. Details are in the OSISM testbed documentation.
