Heya team, Over here at $dayjob, we have an increasing reliance on Kubernetes for both development and production workloads. Our tools are maturing and we're hoping that they might be of interest to the wider community. I'd like to see if there's community interest in receiving some/any of them as a contribution. I think we'll also need a plan from ASF Infra that makes kubernetes available to us as a project.
We have implemented a basic stack of tools for orchestrating ZK + HDFS + HBase on Kubernetes. We use this for running a small local dev cluster via MiniKube/KIND ; for ITBLL on smallish distributed clusters in a public cloud ; and in production for running clusters of ~100 Data Nodes/Region Servers in a public cloud. There was an earlier discussion about using our donation of test hardware for running more thorough tests in our CI, but one of the limiting factors is full cluster deployment. I hope that the community might be interested in receiving this tooling as a foundation for more rigorous correctness and maybe even performance tests in the open. Furthermore, perhaps the wider community has interest in an Apache licensed cluster orchestration tool for other uses. Now for some details: The implementation is built on Kustomize, so it's fundamentally transparent resource specification with yaml patches for composability; this is in contrast to a solution using templates with defined capabilities and interfaces. There is no operator ; it's all coordinated via init/bootstrap containers, shell scripts, shared volumes for state, &c. For now. Such a donation will amount to a code drop, which will have its challenges. I'm motivated via internal processes to carve it into smaller pieces, and I think that will benefit community review as well. Perhaps this approach could be used to make the contribution via a feature branch. Is there community interest in adding such a capability to our maintained responsibilities? I'd hope that we have several volunteers to work with me through the contribution process, and who are reasonably confident that they'll be able to help maintain such a capability going forward. We'll also need someone who can work with Infra to get us access to Kubernetes cluster(s), via whatever means. What do you think? Thanks, Nick & the HBase team at Apple
