flink on kubernetes

[祁明良 <mq...@xiaohongshu.com>]

Hi all,


We are trying to build our flink cluster on k8s, but there seems to be not enough materials about details.

Firstly, we learned how to build a standalone cluster on k8s and run all the jobs inside it.

The question is like are we building a cluster for all the jobs or one job per cluster?

To us, a cluster for all the jobs leads to bad isolation and some job may require different configurations. But we don't find any material talking about how to build like one job per cluster on k8s, something like running one flink job on yarn. Do we have to wrap the things by ourself or there's something we missed?


Best,

Mingliang

Hi Mingliang,

I'm currently writing the updated documentation for Flink's job cluster
container entrypoint. It should be ready later today. In the meantime, you
can checkout the `flink-container` module and its subdirectories. They
already contain some information in the README.md on how to create a job
cluster container image and run it via docker swarm and on K8s.

Cheers,
Till

Hi mingliang,

Yes, you are right, the information that Flink on Kubernetes' current
documentation can provide is not very detailed.
However, considering that Kubernetes is so popular, the Flink community is
currently refining it, this work is mainly done by Till, and you can follow
this issue [1] to get the latest progress, or you can ask Till if you
summarize your list of questions. Regarding the mode of Session mode or
single job, I personally recommend that you use the mode of Single Job
because it provides better isolation guarantee.

Thanks, vino.
