Re: Cannot upgrade helm chart
Hello, And if you want to go for a deployment, consider using a statefulset instead. This way you are certain that, on upgrade, it will let the old version exit before it starts the new version.

If you are only running long lived streaming jobs, this may be acceptable for you, but makes it difficult to stop the job with a final savepoint (since it will exit after completion). What you could look into with the Job approach is building an upgrade procedure that takes the final savepoint, allows the Job to exit, then deploys a new helm release with the upgraded image and savepoint path. It is more expensive, but may be more flexible.

Cannot upgrade helm chart
Hello flink community, I am deploying a flink application cluster using a helm chart , the problem is that the jobmanager component type is a "Job" , and with helm i can't do an upgrade of the chart in order to change the application image version because helm is unable to upgrade the docker image of the kind "Job" so i am wondering if i can change the jobmanager kind to a "deployment" and if there are any drawbacks in doing do. Thanks.
