Hey Gluster Community, As you might be aware, there is an effort in the kubernetes community to remove in-tree storage plugins to reduce external dependencies and security concerns in the core Kubernetes. Thus, we are in a process to gradually deprecate all the in-tree external storage plugins and eventually remove them from the core Kubernetes codebase. GlusterFS is one of the very first dynamic provisioners which was made into kubernetes v1.4 ( 2016 ) release via https://github.com/kubernetes/kubernetes/pull/30888 . From then on many deployments were/are making use of this driver to consume GlusterFS volumes in Kubernetes/Openshift clusters.
As part of this effort, we are planning to deprecate GlusterFS intree plugin in 1.25 release and planning to take out Heketi code from Kubernetes Code base in subsequent release. This code removal will not be following kubernetes' normal deprecation policy [1] and will be treated as an exception [2]. The main reason for this exception is that, Heketi is in "Deep Maintenance" [3], also please see [4] for the latest push back from the Heketi team on changes we would need to keep vendoring heketi into kubernetes/kubernetes. We cannot keep heketi in the kubernetes code base as heketi itself is literally going away. The current plan is to start declaring the deprecation in kubernetes v1.25 and code removal in v1.26. If you are using GlusterFS driver in your cluster setup, please reply with below info before 16-Aug-2022 to d...@kubernetes.io ML on thread ( Deprecation of intree GlusterFS driver in 1.25) or to this thread which can help us to make a decision on when to completely remove this code base from the repo. - what version of kubernetes are you running in your setup ? - how often do you upgrade your cluster? - what vendor or distro you are using ? Is it any (downstream) product offering or upstream GlusterFS driver directly used in your setup? Awaiting your feedback.
