[Question] Kubernetes

Hello,

I would like to know if someone tried with Kubernetes (init with kubeadm).
Because, I'm truly thinking about stopping with docker swarm since I'm not sure about the future with this.

And, this software is really what I'm looking for backing up my data.

Thanks you !

I have to admit I don't know anything about Kubernetes, so I might not be a good reference here. My gut feeling tells me this image probably won't work well with Kubernetes as soon as you rely on functionality that requires interaction with the Docker Daemon (starting and stopping containers, executing commands) as Kubernetes will have a different API than Docker. If you just create and upload archives it should work just as well though. All of this might be wrong and is just a guess.

I have no idea how hard it would be to make it work, but if anyone has feedback on this I am happy to learn about it.

Hello,
Thank you for your answer.

Okay, I see ! That's true docker is quite easy to use and a backup feature like that could be very useful in k8s.
If someone tried already ?

I run this image on Kubernetes using a CronJob and it works great:

apiVersion: batch/v1
kind: CronJob

  schedule: "@weekly"
