I think it should be possible to use Helm pre-upgrade hook to take savepoint and stop currently running job and then Helm will upgrade image tags. The problem is that if you hit timeout while taking savepoint, it is not clear how to recover from this situation

It would be relatively easy to create a chart for simply deploying standalone Flink resources via the Kubernetes manifests described here[1], though it would leave out the ability to upgrade your Flink application via Helm. If you need upgrade capabilities (which most people do) and need to use Helm, the Kubernetes Operator approach is the only option for an "all-in-one" experience. In addition to the GCP Operator you mentioned, there's also a Helm chart for Lyft's Operator by lightbend[2] as well as an operator for the Ververica Platform with support for Helm that I've built here[3]. Are you already running Flink on Kubernetes, or just looking to get started easily? Best, Austin [1]: https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/resource-providers/standalone/kubernetes/ [2]: https://github.com/lightbend/flink-operator [3]: https://github.com/fintechstudios/ververica-platform-k8s-operator/blob/master/docs/guides/deployment.md On Mon, May 17, 2021 at 11:01 AM Pedro Silva <pedro.cl...@gmail.com<mailto:pedro.cl...@gmail.com>> wrote: Hello, Forwarding this question from the dev mailing list in case this is a more appropriate list. Does flink have an official Helm Chart? I haven't been able to find any, the closest most up-to-date one seems to be https://github.com/GoogleCloudPlatform/flink-on-k8s-operator. Is this correct or is there a more mature and/or recommeded helm chart to use? Thank you.
