scaling Mysql Database in kubernetes

[Montassar Dridi]

Besides Vitess, what is a recommended way for production to scale database pods in kubernetes 

[Prashanth B]

What do you mean by "scale", simply add more instances or deploy pods in some scalable topology (i.e scale group membership)? 

RCs/deployments are the fastest way to scale up, but not necessarily the best or safest when it comes to protecting state (eg: https://github.com/kubernetes/kubernetes/tree/master/examples/mysql-wordpress-pd). In comparison, StatefulSets are slower to scale but make it easier to deploy interesting topologies (eg: https://github.com/kubernetes/kubernetes/blob/master/test/e2e/testing-manifests/petset/mysql-galera/petset.yaml). 

Don't deploy either example to production without prior testing.

thanks for your help 
both solutions requires a lot of testing and maintenance, in comparison with scaling and deploying an application in kubernetes.

I was just looking for another straight forward and easy way to deploy and scale a database before testing the solutions you mentioned

There's also a charts repo, if you're looking for easy templated deployment: https://github.com/kubernetes/charts/tree/master/stable

Hello I tried to test with StatefulSets but I get this error

 API version "apps/v1beta1" isn't supported

I think is not been release yet but Is there a way to enable on my GKE and play with it

Kubernetes 1.5 is not released yet. So, you can't use StatefulSet on GKE yet.
