Hey all, Yeah, I'd be interested to see the Helm pre-upgrade hook setup, though I'd agree with you, Alexey, that it does not provide enough control to be a stable solution.
@Pedro Silva <pedro.cl...@gmail.com> I don't know if there are talks for an official operator yet, but Kubernetes support is important to the community and has heavy investment, as seen on the Roadmap[1], so it will only get better! Currently, the recommended way to get started on Kubernetes is with the "Native Kubernetes" resource manager[2], which allows running Flink Applications on Kubernetes from the command line and might work for you. Hope that helps!
