Today, we are announcing the availability of GCS (Gluster Container
Storage) 0.1. This initial release is designed to provide a platform for
community members to try out and provide feedback on the new Gluster
container storage stack. This new stack is a collaboration across a number
of repositories, currently including the main GCS repository , core
glusterfs , glusterd2 , and gluster-csi-driver .
== Getting started
The GCS repository provides a VM-based (Vagrant) environment that makes it
easy to install and take GCS for a test-drive. See
for a set of instructions to bring up a multi-node cluster with GCS
installed. The Ansible-based deploy scripts create a Kubernetes cluster
using kubespray, then deploy the GCS components. These playbooks can also
be used to bring up GCS on other Kubernetes clusters as well.
== Current features
This is the initial release of the GCS stack. It allows dynamic
provisioning of persistent volumes using the CSI interface. Supported
1x3 (3-way replicated) volumes
GCS should be able to recover from restarts of any individual
GCS-related pod. Since this is the initial version, bugs or feedback on
improvements will be appreciated in a form of github issue in the
== Next steps
Adding e2e testing for nightly validation of entire system
Will be adding gluster-prometheus for metrics. The work under this can
be tracked at the gluster-prometheus repo 
Starting work on operator to deploy and manage the stack through anthill
Bi-weekly update to the community on the progress made on GCS.
== GCS project management
GCS and the other associated repos are coordinated via waffle.io for
planning and tracking deliverables over sprints.
Cross-repo coordination of milestones and sprints will be tracked
through a common set of labels, prefixed with “GCS/”. For example, we
already have labels for major milestones defined like ‘GCS/alpha1’ ,
‘GCS/beta0’. Additional labels like 'GCS/0.2'/'GCS/0.3'/... will be created
for each sprints/releases so that the respective teams can tag planned
deliverables in a common way.
== Collaboration opportunities
Improving install experience
Helping w/ E2E testing framework
Testing and opening bug reports
== Relationship to Heketi and glusterd (the legacy stack)
While GCS is shaping the future stack for Gluster in containers, the
traditional method for deploying container-based storage with Gluster (and
current GlusterD) and Heketi is still available, and it remains the
preferred method for production usage. To find out more about Heketi and
this production-ready stack, visit the gluster-kubernetes repo .
