SUSE releases beta for container as a service platform

Germany-based open source company SUSE Linux has released a beta image for the container as a service platform that it first disclosed at its annual company conference last year.

According to a statement from the company, SUSE's CaaS is an application development and hosting platform for container applications and services.

It enables the user "to provision, manage, and scale container-based applications and services, so you can focus on development of container applications and meet your business goals faster while saving costs in developing & maintaining container infrastructure".

According to the release timetable, the first stable release is expected to come out on 19 July. Prior to that, there will be a third beta on 27 April, a release candidate on 24 May and an internal general maintenance release on 29 June.

The beta comes ready to run out of the box and has the following features:

  • Btrfs with snapshots and rollback for transactional updates;
  • Read-only file system with OverlayFS for /etc;
  • cloud-init for initial configuration (Network, Accounts, Salt);
  • Salt for full system configuration; and
  • Controller node with dashboard to manage cluster.

The base operating system and snapshots are read-only while sub-volumes for data storage are read-write.

Detailing the CaaS to iTWire last year, developer Simone Arsene said there were three components: a microOS which was derived from SUSE's enterprise Linux distribution, Kubernetes, which handles the management or orchestration of the containers, and the container engine Docker plus the management utility Salt which was used for setting up all the components.

"MicroOS has a new mechanism for updates which is known as transactional updates. We use functionalities from SLES 12 service pack 2, which was announced this week, and a set of updates are put together and shipped to machines that then update on their own," she said at the time.
